Gwen speeds out to the top of the tower and lands opposite of Nine. They growl and go to tackle each other. A shockwave bursts from the tower, blowing them both back, but they stay standing on the tower.

"Nine, enough. We can still end this. Together." Gwen said.

She dodges a series of bullets.

"Together?" Nine asked, annoyed.

Nine floats up while Gwen speeds around the tower.

"You only care about getting back to your precious Green Hill. And you even hurt my feelings by yellimg at me."

Nine fires more bullets down to the edge on the tower, causing Gwen to halt.

"I care about all of this. You, the Shatterverse, and everyone inside of it. I know you do too. And that Prism power--" Gwen started.

"Is my ticket to protecting my new world. Once I take the remaining Prism energy that's in your brother, the Grim will be saved. Look around. You've already lost and you don't even know it. Your so-called friends won't be doing any more fighting. Meanwhile, my army has one purpose: To get your brother's energy." Nine interrupted, Gwen turning back to look around the Grim.

Grim Birdies fly up towards the tower and tries to grab Gwen. She leaps off part of the structure, spin attacks one of them and lands on another, looking at Nine.

"It's gonna take more than just a few knockoff robots to slow me down."

Gwen jumps off at the opportune moment to defeat a Grim Birdie using its own bullet.

It spin attacks three more of them. Nine grunts as Gwen lands back on the tower. Nine points its mechanical tails and gathers energy from the Paradox energy beam.

"Need... more... power!"

The dome fluctuates, with purple rocks appearing in the starry sky.

Inside the tower, the Paradox Prism starts shaking. On the ground, grim robots flicker and restore power as Sonic looks around.

"It's working. They're losing power." Sonic said.

Alpha Grim Sonic's eyes open. Gwen watches on and Nine continues generating prism energy. The dome starts shrinking, with battlefield crystals disappearing through the dome's edge.

"Sure you can handle all that juice, pal?"

Nine turns to Gwen, with its mechanical tails glowing white. It shoots at Gwen, causing her to fall off the tower. She screams as she heads towards the spiky crystals at the bottom of the citadel.

"Catch her before she hits the spire. I need to her safe from being hurt and need Sonic's energy." Nine ordered to the Grim birdies as they swoop down.

Sonic sees Gwen falling and runs to save her as his shoes start glowing. He jumps, catches her and lands on appearing panel tiles to avoid the spikes.

"Huh?" Sonic questioned as he appear when he puts his foot down.

"Sonic, what happens to your shoes?" Gwen asked.

"I was wondering what these puppies do in this place."

"Then, take me back to the tower"

"On it. Get ready for some fancy footwork."

Sonic speeds out along the tiles while carrying his sister to take recovering before using her wind power. Grim Birdies attack him. He ducks under to dodge one of them and jumps over the other one. He starts spinning along the tiles and Homing Attacks both of them. He peels around towards the tower at the top of the citadel and looks at Nine.

"I never should have given you those Regulators." Nine grunted.

Nine shoots back at Sonic, who peels around the sky in various directions, missing the target.

"More power!"

Nine generates more power from the Paradox Energy beam.

He shoots a series of bullets at Sonic, hitting the target, but a tile pops up as Sonic puts both of his hands out, acting as a shield. Sonic holds the shield and tries to hang on. Another tile appears as Sonic stretches his back leg out. As soon as the bullets disappear, Sonic lets go, and the shield disappears. He looks at his gloves.

"Huh? Even better!" Sonic chuckled, flexing his muscle at Nine.

"Now that's some power, bro!" Gwen said, fully recovered herself and used her wind power to float around.

"No!" Nine grunts and fires again.

Sonic and Gwen peels along the sky in a loop-de-loop. They sticks their arms out and holds a shield and bubble to block incoming bullets. Nine unleashes a powerful beam at Sonic. Sonic falls upon impact and starts screaming and Gwen goes after him. Behind the confused Nine, Sonic is standing on an invisible tile portraying a screaming voice beside Gwen.

"Splat!"

Nine turns, but Sonic and Gwen quickly Spin attacks him as they travel around the energy beam. They let go. Nine fires green lasers at Sonic, holding a shield to block the attack. Gwen runs with the shield of bubble and gets closer to Nine. Nine groans and holds his head. Having run out of energy, he drops onto the tower. Sonic, caught out by the velocity, drops the shield and falls onto the tower as well with a thud, holding his head for a brief moment before kneeling.

"You're looking pretty tired. Sure you're not ready to give up?" Gwen asked, floating down to safety.

"Give up? I can't. You're the one who put me in this position." Nine moaned, dropping his mechanical tails, frowns and scowls as he starts hovering.

He lapses, clenches his fists and sets up his mechanical tails to generate power from the paradox energy beam. Sonic and Gwen flinches and covers their eyes while they looks up. The lighting on the Grim Robots flicker, along with the dome fluctuating in appearance. On the ground, Rebel stirs and eventually gets up.

"Now!" Rebel punches a Grim robot.

Other allies get ready to battle. Dr. Babble grabs Alpha Grim Rouge and throws it towards Prim Rouge, who throws it over to Rebel, who kicks it down to the ground. Dread punches away a Grim Knuckles.

"Ha ha har, yeah!"

He swings another Grim Bot away with his sword.

Knucks, standing on a crystal, punches two more Grim robots. Shadow spin attacks a Grim robot, causing it to collide with a Grim Birdie. A Grim Amy heads towards Thorn Rose and Birdie, but they dodge. Thorn and Grim Amy go head-to-head. She hammers the robot away. Birdie swoops down, carrying Thorn, and takes off and T'Challa attacks the grim robots by using jaws to break it into pieces. Sonic and Gwen looking down from the tower, delighted.

"It worked. The plan worked!"

They starts looking back nervously as Nine generates more energy from the paradox beam. His mechanical tails glow white but stops and pants.

"Fully charged. Now you will feel the full force of my..."

Nine hears a rumbling in the distance and turns to where it's coming from.

"Huh?"

Tensing his hand and frowns in fury.

"What?"

Nine looks down from the tower. Sonic tries to sneak in a spin attack towards him but is forced to use the shield as Nine lasers back at him. Sonic and Gwen pushes Nine down to the top of the tower as they continue straining.

"You tricked me. Clever. But betrayal comes easy to you. How did you two do it?" Nine said.

"One, sneaky great plan." Sonic explained.

"Two, 'cause they trusted us." Gwen added.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~ FLASHBACK ~

"We're running out of time. I need you, all of you, to listen to us." Gwen said.

"Why should anyone listen to you?" Dr. Deep asked

"Because we know how we can win." Sonic said.

"And how do you propose we do that?" Rebel asked.

"By letting him think he's won." Gwen answered with a smile.

~ FLASHBACK ENDS ~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Sonic, Gwen and Nine continue to struggle.

"You can't protect your world, fight us and power your army." Gwen said.

Nine yells as he powers up, forcing Sonic and Gwen up in the air. The Shield where Sonic is starts disappearing.

"Whoa, whoa, whoa, whoa. Ah!"

Sonic and Gwen jumps off and falls.

Meanwhile, on the ground, Gnarly punches his Grim counterpart on the head. Black Rose, standing next to Rusty Rose, jumps and swings her sword at Alpha Grim Amy. After two slashes she kicks the robot into the wall. Rusty flips and smacks the robot down with her legs, losing its hammer. Dr. Babble grabs Alpha Grim Rouge and slams it down to the ground, creating a plume of dust. Shadow grunts and goes after Alpha Grim Sonic. He kicks it in the air, causing it to fall face down. Shadow walks towards it and steps on its head, looking at Nine.

"Nooo!" Nine shouted furiously.

Rebel lands next to Shadow.

"We did it!" Rebel cheered.

Her allies cheers in celebration, while Sonic and Gwen smiles back at them.

"You think this is over, don't you?" Nine sighed, annoyed.

"It is over. Now let's save the world... together." Gwen said, softly.

"I didn't start the decay, the Chaos Council did. Then you two betray me and bring everyone here to attack me. You forget who controls the Prism."

Nine grunts and rises, generating more power from the Paradox Energy Beam. The dome destabilizes and fluctuates again.

"What are you doing?" Sonic asked.

"I'm accelerating the decay. Soon, you'll have no choice." Nine said.

Purple rocks float upwards in the sky. The dome starts shrinking and bolts of energy light up around the Paradox prism. Nine, with fully charged mechanical tails, turns and fires green lasers down at the fainted Alpha Grim Robots, reviving them completely.

"What... is... happening?" Gnarly asked.

"Huh? No!" Rebel gasped.

The Alpha Grim robots move forward.

"Nine, this isn't you. You'll destroy everything." Gwen tried to stop him.

Nine ignores her and powers up his mechanical tails. Grunting and yelling, he fires rounds of bullets at Sonic - who tries to block it with his shield, but is sent flying back. Sonic falls and bounces on invisible tiles in the air, landing on his front, groaning. Now Gwen stands alone with Nine.

Meanwhile, on the ground, the Alpha Grim Knuckles punches Knucks, Denizen 1998 and somersaults its way to punching Prim Rouge. It jumps close to Dr. Deep.

"Oh, no."

Dr. Deep flies up with his mech, but the Alpha Grim Rouge kicks him down, nose-diving back to the ground. The Alpha Grim Amy hits Black with its hammer, along with Rusty, Birdie and Thorn. Alpha Grim Sonic grabs hold of Shadow's arm and tosses him in the air, dropping helplessly to the ground. Nine extracts more beam energy from the Paradox Prism and fires a series of bullets at Sonic, whose shield grows bigger. Gwen floats up and saves Sonic using her bubble shield to save them both. The dome's background appears and disappears.

"You're not just destroying your home. You're destroying yourself." Gwen said, while holding her shield, shots fired.

"I'm protecting my home!" Nine said, while still extracting.

Nine unleashes a powerful beam at the hedgehogs, wiping out the shield and causing Sonic and Gwen to fly back, him landing on the invisible tiles again while she floats again.

"My Grims will eliminate your friends, and my Alphas will be by my side as I do the same to you. All Alphas, attack Sonic... now!" Nine said to Sonic, ordering to the Alpha Grim Robots.

The Alpha Grim robots obey Nine's command and head towards the citadel.

"Gwen is mine." Nine stares at Gwen and glances.

"Hold them back!" Rebel ordered.

"Eat plasma, metal scum!" Squad commander red said, preparing her gun.

Rebel and Red follow their allies towards the citadel.

The regular Grim robots run and attack Sonic's allies. Rusty extends her arm and grabs Alpha Grim Amy on its legs. She pulls it back and tosses it up for Knucks to punch it. The Alpha Grims Knuckles and Sonic halt opposite Dr. Deep.

"Prepare to be amazed."

The Alphas engage in their combat poses.

"Then deceased by the one and only Doc--"

The Alpha Grim Knuckles punches and takes out Dr. Deep, but Mr. Dr. Eggman lands behind it.

"Eat fist, brute!"

Mr. Dr. Eggman punches the robot back. The Alpha Grim Rouge flies up to combat Rebel.

"Take her!"

Rebel kicks her Alpha Grim counterpart and goes after it. The robot lands on its feet, but Hangry jumps on it and traps its arms to the ground with his hands. Thorn and Birdie fly up to combat Alpha Grim Birdie. The robot turns towards them and shoots with its beak, which Birdie dodges. Thorn jumps off Birdie and hits Alpha Grim Birdie on the head with her hammer, causing it to fall for a brief moment until Dr. Babble punches it back. The Alpha Grim Sonic runs up the citadel wall, but Shadow intercepts it with a spin attack, falling back onto the ledge. They look at one another.

"You aren't going anywhere."

They run into each other again. Shadow punches, kicks and punches Alpha Grim Sonic, causing it to fall down, but Shadow goes for it again. Meanwhile, Nine watches as he generates more power from the Paradox energy beam. He clenches his fists and growls. He yells as he shoots green lasers down at the defeated Alpha Grim Robots, causing them to rejuvenate. The Alpha Grim Amy is rebooted and ready for combat, along with regular Grim Amys and they walk towards Sonic's allies. Another beam revives Alpha Grim Knuckles, followed by Alpha Grim Rouge. It takes off, turns and swoops. The Alpha Grim Birdie is also being revived and it takes off.

"It's not over. His power supply is endless." Rebel reminded.

Meanwhile, at the top, Nine extracts more beam energy, while the siblings looks at the fluctuating dome and the purple rocks in the air. Sonic was about to talk to nine, but Gwen went first, because she knows what to do as she floats down to talk.

"Nine. We both dreamed of a better place, a better way of life. But your world is falling apart." Gwen said desperately, walking towards her current enemy.

"A small sacrifice which I'll fix soon enough with your brother's energy." Nine said angrily.

Gwen frowns back at him. Nine unleashes a laser at Gwen, but she dodges it as fast as she can.

The rest of Sonic' and Gwen's allies war-cry and raise their weapons. They charge towards their enemy. Jack takes out a Grim robot with his sword, while two Eggforcers punch a Grim Knuckles.

"Yes!" Dr. Don't cheered, raising his controllers in celebration.

Deep, Dread and Rebel battle against Grim Robots. Black flips over to dodge a Grim Amy's attack, but Rusty punches it, causing it to drop its hammer, and smacks it down. Dr. Babble hits another Grim Robot and throws a Grim Knuckles in the air for Birdie and Thorn to finish it with an attack. Gnarly punches a grim robot, back-flips to defeat another one, and punches a third approaching Grim robot. The dome starts rumbling again. The camera cuts to the downed Grim Big. Its thrusters from its arms, base and tail ignite. With a hole in its head, the Grim Big begins to rise. Gnarly is startled by what he sees along with Black and Rusty. Dr. Babble falls over in-front of some Grim robots, while Rebel looks at the rising giant robot in shock. Grim Big slowly moves forward, with the allies staring at it.

"Oh, no... Big is back!" Rebel gasped.

At the top of the tower, Nine yells and fires more bullets at Gwen but tries not to hurt her at the same time. Gwen dodges and jumps from air power, making her way next to Nine. Nine growls furiously, while Gwen pants in exhaustion. Gwen having a thought about one and only choice she got, but she's not going to like it.

"This is gonna hurt me a lot more than it's gonna hurt you." Gwen said.

"What?" Nine questioned, confused.

Gwen gets up floating in midair, her body glowing white along with her eyes to unleash her full power. Gwen creates a massive gust of air. Pillars of earth disintegrate and move toward Gwen as other pieces of rock rise up to surround her. Water also rises toward Gwen as she creates a ring of fire around herself. The earth begins to create a ring inside the air sphere as the water continues to rise up and form another ring inside the earth sphere. Gwen is surrounded by a ring of water, a ring of earth, a sphere of air and a ring of fire. Just like from dream in the No Place.

Nine, Sonic and Shadow who's looking up to see her full power but looks in worry because Sonic knew it happened before.

"Sis! Don't use your full power! Do you remember what happened last time you use your full power?" Sonic reminded her.

Gwen looks at her brother with a wink, knowing she's doing what's best for protection. Gwen uses her earth pullers to forcing him into the wall's edge. Gwen look at Nine. Nine accompanies some Grim Robots to the top of the tower.

"Bring me Sonic. I need his energy. Gwen! You'll regrets for fighting me!" Nine ordered, flying up.

"As you wish." Gwen said and they both fight in the sky.

Sonic grunt and charge at his robotic counterparts. Nine grunts and shoots at Gwen, but Gwen blocks it using a shield of air, and fires at Nine. Another Grim Sonic approaches from behind and takes Sonic down. Meanwhile, Grim Big and other Grim robots head towards Sonic's annd Gwen's allies.

"What do we do?" Jack asked.

"We do what we always do. We fight to the last one standing!" Rebel said.

The allies yell and stand their ground while their enemy approach. Grim Big deploys Froggy Bombs, hitting the Grim Robots. It uses the swinging tail attack to defeat more Grim Robots.

"Huh? Huh?"

More Froggy bombs take out more Grim robots. The head of a Grim robot stops in-front of the view of Sonic's allies, along with more Grim robot parts falling. Grim Big roars. The light in the cockpit turns on. Sails and Mangey pop up through the hole in its head and wave.

"Ahoy!" Sails greeted.

"Hey." Mangey greeted as well.

"Sails! Mangey! You're alive! But... how?" Rebel asked, flying up to them.

"There was an explosion to be sure but twas nothing we couldn't fly away from. Mostly. Orders?" Sails said, they both spin their tails.

"Stay on top of the Grim-bots and stay safe. The rest of you, remember the plan. Take out the Alphas and the others fall." Rebel said.

"You heard her, Mangey. Light 'em up!"

Sails pushes the levers forward. Grim Big deploys more Froggy Bombs at the Grim robots, with one of them knocking out a Grim Birdie in the air, and another hitting three troopers in one shot.

"Ahh, I love the smell of froggy bombs in the morning." Sails exhaled, and Mangey chuckled.

Jack calls Dread.

"Hold up, Captain. With everyone distracted down here, we could make a serious run at that rock. And with that kind of treasure, we wouldn't just be legends, we would be pirate kings."

Jack runs off.

"Me beauty." Dread smiled, but also have some thoughts about Gwen and Emeraldas saying about love and learning something more than treasure before shakes his head and runs off.

Meanwhile, at the top of the tower, Sonic spins and kicks a Grim Knuckles, while Gwen continues fighting Nine with five elements of power until she starts getting weaker by the minute from using too many powers at once.

"No! I have to have that-- energy."

Nine extracts more energy from the paradox beam, causing the Paradox Prism inside the citadel to shake. The dome fluctuates once again. Nine shoots green lasers in-front of Sonic.

"Look out!" Gwen warned her brother.

Sonic puts up a shield to block Nine's laser attack and Gwen uses fire to circle around nine. Meanwhile, Grim Birdies squawk and shoot at Grim Big. The vehicle shakes, knocking Mangey off his seat. Sails types random buttons on the keypad. As soon as he presses the big button, Grim Big's arm cannons open out and start firing, homing into and defeating some Grim Birdies. Mangey gets back up, but falls again. The Alpha Grim Birdie locks a target onto Sails and Mangey. Sails pushes the big button in desperation. The cannons paralyze and power down. The Alpha Grim Birdie squawks as it gets closer to them and prepares a bullet, while Sails panics as they start mashing random buttons.

"Argh. That's not good."

Eventually, Sails pushes the big button; A horde of Froggy Bombs are deployed. They blow up and defeat the Alpha Grim Birdie. As soon as the smoke clears, Sails and Mangey look at each other. At the same time, Rebel notices the cloned Grim Birdie vanish in conjunction with Alpha Grim Birdie's defeat. Her allies cheer in celebration.

"It's working. The Grim Birdies are out! Press the attack!"

The Alpha Grim Rouge takes out Hangry and Prim. Gnarly jumps off from Birdie and punches the Alpha Grim robot into Prim, who kicks it, T'Challa pounces and breaks it as it hits the ground. Thorn finishes off Alpha Grim Rouge with a hammer attack. The cloned Grim Rouges evaporate, causing Dr. Deep - originally held by one of them - to drop.

"The Grim Rouges are down! Don't stop! Keep going!"

Meanwhile, at the tower, Sonic continues blocking Nine's laser attack with the shield and Gwen continues fights nine. After a while, Nine stops and falls on the tower. With Sonic looking worried, Gwen also falls on the tower as her powers stops and turns her whole body into a shard as her transformation is almost complete. Nine and Gwen gets up looking each other worried as Gwen coughs and moans. Sonic looks around the fluctuating dome in fear. It starts shrinking, with more battleground crystals rise and disappear.

"Nine! Sis! Look! We'll lose everything. You gotta get through to him." Sonic said, pointing them to the shrinking dome.

"Nine! The Grim is falling apart! You have to stop this now!" Gwen added.

Nine glows himself white and unleashes an electric shockwave which hits Sonic and Gwen. As soon as they get up from the tower's edge, Nine summons many more Grim Sonics to battle him. Meanwhile, on the ground, Dr. Deep battles an Alpha Grim Knuckles, but the Alpha robot grabs his mech.

"Oh, no."

It spins him around and tosses him up in the air.

"Ah!"

Dr. Babble slams into the Alpha Grim robot. It carries Catfish, takes him up and kicks him away. Rebel shoots around it on the ground, creating clouds of dust. Catfish burns it from behind with a hot chainsaw, defeating Alpha Grim Knuckles. As a group of cloned Grim Knuckles approach Gnarly, they vanish just as he punches. He chuckles as he looks at his gloves. Rusty extends her torso and scans the area, seeing a group of Grim Amy approach Black and Batten.

"Keep fightin', Batten! We can do this!"

"Aye aye, Capt-- oh!"

Batten gets struck by Alpha Grim Amy. Black yells as they clash with one another, pushing their weapons forward, with Black dropping to a knee. Meanwhile, Jack starts climbing the Citadel and joins Dread. Dread looks up in amazement.

"So much beauty."

"Instead of dying in this desolate wasteland like the rest of these sea dogs, we'll be living like kings."

Dread turns around and looks down at Black straining against her Alpha Grim counterpart. Jack climbs further up the citadel.

"Forget them, Captain. We have to keep climbing."

He continues climbing but Dread ignores him.

"Come on, Captain!"

Dread having more thoughts about his crew, and having flashbacks about Emeraldas and him having adventures together, he and Gwen first met as he kissed her passionately, their dance at night with given her a ring, Gwen sings to Dread to cheered him up. Battle against each other, dread cheered Gwen up by singing, saving Gwen from chaos council and last but not least, Gwen sings another song to dread for giving him hope as they kissed and hugged. The flashbacks ends and Dread was having a tear in his eyes and grins.

The Alpha Grim Amy knocks off Black's sword with its hammer and grabs hold of her. As she tries to loosen its grip, the Grim robot's head turns to Dread gliding towards it.

"Leave her be!"

"Dread?" Black Rose said, astonished.

Dread hits the Alpha Grim robot, freeing Black. The robot hammers down, but Dread dodges, hitting the ground instead, but it swings its hammer to knock Dread's sword off, catching it. It hits Dread with the hammer, causing him to blow back and fall on his belly. Black hits the Alpha Grim Amy back. The sword is thrown high in the air, with Rusty going after it to try and catch it. She extends her arm and catches the sword. She throws the sword in the ground between Black and the Alpha Grim robot. She drops in-front of the downed Dread.

"Leave this one to me." Rusty extends her arms and punches Alpha Grim Amy, taking it away.

"You came for me." Black Rose said, Dread offering a hand to help her up.

"I finally realized there are things more important than a shiny rock. But you already knew that, didn't ye?" Dread said, finally realizing the true meaning of loyalty.

"I suppose I did."

"For now and forever. You'll always have me loyalty." Dread doffs his hat.

Dread dons his cap onto Black, untidily. Black straightens it out.

"Captain Rose." he grinned, showing his shiny gold tooth.

"Did you just call me "Captain"? Emeraldas would be real proud of you if she see you." Black said.

"Aye. She would. Now, what are your orders?" he smiled.

"Grab your sword and let's dole out some pirate justice!"

Black and Dread run for the Alpha Grim Robot. The Alpha Grim Amy prepares her hammer. The sensor on the Alpha's head flickers a target and a warning sign. Rusty looks up at the Citadel's Tower, then back to her Alpha counterpart.

"You don't feel anything, but I do. And that's what makes us different. My masters had me believe that Birdie gave me my inner strength and power."

Rusty presses a button on her chest, opening the cage, revealing Birdie; it chirps as it lands on her finger.

"But I know now it was another lie. Told to keep me under their control. Symbolic of my oppression."

She lets Birdie fly away.

"But I don't need this little bird for power. And this little bird needs to be free. The only thing I need is-- me!"

Rusty extends her arm towards her Alpha Grim counterpart, but it blocks her with its hand, stopping on the ground. The robot jumps and takes Rusty's arm with it, slamming her body down to the ground. She uncontrollably rolls along the ground but manages to get up. They run back and clash again. Rusty extends her arms again. They stick to the ground either side of Alpha Grim Amy. She then retracts her arms, catapulting herself towards the robot and hits it, forcing it back and bumping into some Eggforcer parts. Rusty jumps and punches down, which hits the ground, and swings her legs at the robot. Alpha Grim Amy jumps onto the crystal wall and jumps off to attack, but they miss each other. They clash again. Rusty dodges a few more hammer attacks before standing on her hands and extending her legs towards it, causing it to stop. She punches it, but it retaliates back with a swinging hammer attack, causing her to lie down. The robot swings parts with its hammer at her, causing her to brace herself. The Alpha Grim robot then swings a large piece of spherical robot armor at her, causing her to fly back and roll with it towards the edge of the dome, which she soon chucks it out of the way. The robot jumps and delivers a hammer attack, but Rusty blocks it by holding onto the hammer's shaft with her hands. They push the hammer against each other. Rusty extends her legs under the robot's legs and retracts them, causing the robot to let go of its hammer and fall down. Rusty stands up, now in possession of the hammer, and runs towards her target with the new hammer. In slow motion, Rusty swings the hammer and hits the robot, causing it to fly back and disappear through the dome in a wisp. Birdie flies freely towards Rusty, and lands on her hammer; Rusty showing affection.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Meanwhile, two auras spin into each other as the battle between Alpha Grim Sonic and Shadow is ongoing. Shadow scoops up the robot with his legs, spin jumps, grabs the robot running in a circle, and throws it. Shadow goes on the attack by punching twice but it dodges both blows. The robot rolls under Shadow's body near the edge of the dome. Shadow tries to kicks the robot again but it dodges again. The robot goes for a spin attack but he dodges. They spin at each other, flashing a white light that covers the screen. Alpha Grim Sonic stands, while Shadow is downed and catching his breath, trying to get up, but he drops. Alpha Grim Sonic runs to the Citadel. On top of the tower, with Sonic standing against a group of Grim Sonics and Nine flying.

"It doesn't have to end like this, Sonic. I just need your energy." Nine said.

Sonic prepare himself as the Grim Sonics walk closer to him. Gwen was in no shape at all to fight as she's weaker than ever was before. Sonic get in front of Gwen for his protection this time and Gwen smiles. The Alpha Grim Sonic joins them and steps in-front of the Grim robots. Sonic initiate his combat pose.

"Take him down! And bring me Gwen!" Nine ordered while looking at Gwen with worry as he never wants this far.

The Grim Sonics step forward. Behind the duo, Shadow grunts and spins up to the top of the tower.

"We are not finished!" Shadow said, diving in mid-air.

Shadow spins again and hits Alpha Grim Sonic on the tower, causing an explosion and defeating it. As soon as the smoke clears, the cloned Grim Sonics vanish.

"No! How?!" Nine asked in agony.

"I... am the ultimate... life form." Shadow answered, gets up, breathing.

"Modest too!" Sonic said, popping up from behind.

"Shadow. You're okay" Gwen said weakly as she coughed and Shadow looked at her, scared and kneeling to her aid.

"Gwen, you don't look so good, and you're covered in shards." Shadow said worried, learning she'll soon disappear again as before.

In fury, Nine yells and fires different colored electric pulses at the trio. While Shadow suffer and struggle from the energy, Sonic blocks the attack and protects Gwen using his shield. Sonic and Gwen looks up at the dome, which starts shrinking.

"We're losing ground. Get to the Citadel!" Black Rose said.

At the bottom, Black's allies climb onto the Yolkomotive. Shadow continue to struggle, groaning in pain.

"He's not gonna stop." Sonic said.

He puts away the shield and spin attacks Nine, stopping his laser attack. They both fall, while Shadow recover and helping Gwen up. Sonic and Nine fall together through the tower, continuing to fight each other. Nine hits Sonic's regulator and kicks him.
