Opening - Ben 10 Ultimate Alien Theme

(^)(^)(^)(^)(^)(^)(^)(^)(^)(^)(^)(^)(^)

Disufiroa started walking towards Raven, who draws out a yellow (electricity) blade from her odachi and started walking towards him as well. They did this until they're at maximum three hundred meters apart, before they started running towards each other with a battle cry/roar.

The Frozen Seraphim Elder Dragon creates three ice crystals out of nowhere and launches them towards Raven whilst firing a fireball from his mouth. Raven, with her smaller size and more focused, dodges every single one and jumps at the last second before Disufiroa could hit her and starts slashing at his back.

He roars as he took flight and bucks around trying to get her off his back, but she held tight and kept lashing until her blade broke and switches for another red blade and slashes at his back again. Knowing he is vulnerable to fire and electricity, he felt intense pain from the attack. Disufiroa decides to dive bomb whilst covered in ice. Not to kill Raven by dive bombing, but to kill her tribe with a surprise attack.

When he lands with a thud, several ice pillars came out of nowhere and froze unfortunate bandits. After several seconds, Disufiroa roars as the ice pillars shatter, taking the frozen bandits with them. Those who didn't get frozen are knocked away by the chunks ad some are crushed to death. They remaining decides to run after they realize he coming for them and starts killing.

Raven quickly catches on the act and jumps down his back. When he felt her get off him, he quickly turn and fires an intense dragon beam, hitting her and sending her sprawling into the ground. Raven gains her senses and draws out a blue blade as she points at the Frozen Seraphim Elder Dragon, who chuckles, much to her confusion.

"Hmph! You may be able to harm me before, but after that attack, it will be useless!" Disufiroa states confidently. After Raven got hit, she is now affected by the Dragonblight, a status effect which makes any elemental attacks and other status effects useless for a while and decreases raw strength by 50%.

Raven growls before she is covered by blue aura and ice crystals floating around her whilst floating. She is now using her Spring Maiden powers. Disufiroa sees this and decides to do the same. A storm of fire and ice surrounds him.

Disufiroa roars as he flies towards Raven. Raven summons a large blue sword made of ice as she flies towards Disufiroa. She ducks under a lunging bite from him and starts swinging her blade against his chest spikes really hard. He roars in anger before swiping Raven away with his left claw.

The Spring Maiden recovers and sheathes a red (fire) blade. Disufiroa fires another dragon beam, but Raven summons a portal, enters and, disappears when the attack is about to hit her. Frustrated, the Frozen Seraphim Elder Dragon looks left and right for her. Then a red portal appears above him and Raven comes out and, with one good swing, breaks the horn of Disufiroa.

He roars in agony as he is also stunned by the attack. Raven lands in front of him and held out her right palm. A blue glow is seen as she froze Disufiroa's front legs.

"Damn you!" He roars, trying to break free, but he is instantly freezing faster. With a final roar, Disufiroa is frozen with his head raised. Raven smirks as the bandits, who are hiding, cheered for their leader, while the survivors looked on in horror.

"I have to admit, not many can hold their own against me, even when I'm holding back." Raven states as she summons for a giant broadsword made of ice. "But like I said before, the strong lives, and the weak dies!" With that, she dashes froward and readies her blade towards the encased Frozen Seraphim Elder Dragon to finish him once and for all.

As Raven launches herself forward for the final kill, Disufiroa began to recall the memories from the past.

\/\/\/\/\/

A portal from out of nowhere appears above his village.

His village being invaded and burned to ash.

His fellow hunters dead and their bodies littered every where.

His mother and sister dead as he crawled his way towards them.

"He's too damn strong!"

"We need reinforcements, NOW!"

"MOM! JESSICA!"

"What a worthy foe you could've been. Too bad for your family though."

"J-Jack, I'm sorry..... I c-couldn't watch you grow up anymore..... please..... live a good life..... for me..... for your sister...... a-and for the sake of the village....."

"I'm s-sorry big b-brother..... but I promise me and m-mommy will watch over you....."

/\/\/\/\/\

A single tear made its way on his cheek before his grief turns into anger.

Just moments before Raven could deliver the fatal blow, the ice encasing the Frozen Seraphim Elder Dragon breaks as he roars in uncontrollable fury. She is sent back by the wind as she regains her footing. Raven looks up and is surprised when she noticed Disufiroa breathing heavily.

Impulsively, Disufiroa stands on his hind legs and roars with all his might as he underwent Ultimate Evolution.

He grew longer until he is as long as two school buses. His broken horn somehow returns with two more on each side of it. Orange now mixes with his silver colored body and purple mixes with red. His chest spikes and lower jaw spikes grew to at maximum 4 feet long with yellow mixing with the blue tips. And a other pair of eyes appears above his original pair.

"ULTIMATE DISUFIROA!" He roars out toward the heavens. The bandits stops cheering as they look on in horror. The survivors did the same, though some cheered for their savior.

Ultimate Disufiroa stops roaring as he glares down at Raven, who looks up in pure shock. "Now. I'm. MAAAAAAAAAAAAAAAAAAD!" He fires a beam consisting of the Dragon, Fire and Ice Element that hits Raven full-force. Raven screams in unimaginable pain as she tumbles to the ground several times.

But before she could stop, Ultimate Disufiroa raises his ice-covered claws and slams the ground. A giant pillar of ice beneath Raven that drags her up. He then slams his other claw, generated by fire and also slams it down. The clouds darken as a huge fiery meteor is revealed. (1)

The ice pillar, which still carries Raven, has collide with the fiery meteor as a massive explosion of fire and ice sends a shockwave. Raven screams in absolutely agony as she fell to the ground with frosts and burns covering her body.

She moans in pain as she tried to stand up. However, she heard footsteps and sees Ultimate Disufiroa. "I could kill you right now and be done with it," Ultimate Disufiroa snarls, but manages to maintain a neutral expression. "But that could be too merciful. Instead I'll do something different."

He flicks one of his claws and Raven is encased in ice with her head as an exception. Ultimate Disufiroa grins as he then looks at the bandits, who froze in fear. "You watch in amusement while some of the survivors of this village are forced by to watch their loved ones die by your "family"." Ultimate Disufiroa spreads his wings. "So why not let the survivors watch as I kill your "family" as well!" He said.

"No!" Raven cried out.

But it's too late, Ultimate Disufiroa roars as he creates ice crystals that are burning with flames, but never melt. With a roar, he fires a intense fire beam with ice and dragon swirling around it as his flaming ice crystals homes in. The fire beam killed multiple bandits as projectiles kills the slower ones.

The survivors could only look on in shock and awe as Jack decimated their murderers. Though some mother's covered their children's eyes and eyes to avoid the gory scene, others watch in satisfaction that the bandits are getting what they wanted.

"Who is he?" A man said in awe.

"I don't know either, but it sure seems he took our village being raided seriously." Another man said.

"Could it be that his village is raided as well and seeing ours reminds him?" A woman asks.

"Poor boy. I feel sorry for him." The old man mutters. The rest nodded in agreement.

(^)(^)(^)(^)(^)(^)(^)(^)(^)(^)(^)(^)(^)

Meanwhile, on the battlefield, bodies of bandits are littered across the ground with frosts and scorches surrounding them. Those that remain, which are very few, are huddled in a cowering position as Ultimate Disufiroa hovers above them.

"Here's what I'm going to do." Ultimate Disufiroa took a deep breath before continuing. "You will take your leader here and go back to where you came from and never, ever, return." He stated. "For if I do see anyone of you near this village again, nothing, not even bones, will remain when I'm done with the lot of you. Got it?!" The nodded quickly in fear as one even pissed his pants.

"Good. Now scram!" The bandits didn't need to be told twice as they picked Raven (who is now thawed out of the ice, but is now pissed and frightened) and ran away with their tail between their legs. Ultimate Disufiroa stands on his hind legs as he roars triumphantly. After he stops roaring, he turns back to where the villagers hid. He devolves back to his base form.

"It's safe to come out now." He spoke in a more softer voice.

Soon the surviving villagers walks out of their hiding place as they cheer for their savior. The old man slowly walks up to Disufiroa. "Thank you, young man. If it weren't for you, they would have killed us all." He said.

"Just doing my job sir." The Frozen Seraphim Elder Dragon said before asking. "Also, can kindly tell me where this "Vale" would be."

The old man nods as he points west. "Just go there for 10 miles and you'll reach your destination."

"Thank you." Disufiroa said as he turns and spreads his wings, preparing to take flight

"Wait!" The old man calls out, catching Disufiroa's attention. "We haven't know your name."

The Frozen Seraphim Elder Dragon stood silent for a moment before he answers without looking at him. "Jack. Jack Andros." He confirms. "But to those who disturb peace and bring harm to the innocent............... I am the Monster Shapeshifter." With his MonTrix still using Master Control, he changes without touching the symbol.

He is now a wyvern-like creature with a spiked tail with the center being the longest. Blue eyes with a bird-like beak. His body is colored with red, black, yellow and orange with spikes on his wings and ankles.

"RATHALOS!" The King of the Skies roars out as he flies away from the village. Once again, the people cheers for him and chants his name as he disappears from their view.

Vale, Apartment

Jack, back in his human form, manages to find an apartment that is rent-free and decides to spend the few nights there. The room consists of a regular sized bed, a huge holographic TV from the projector in the front of the room, a bathroom with a sink and shower, and a small nightstand near the bed.

He sighs as he went out of the shower with only a towel covering his lower body. After changing his clothes, sat on the bed and sighs. Putting his left hand on his pocket, he pulled out two pictures and the Nemetrix. The first picture was him and his with his mother and sister. His mother had a curvaceous body with blonde hair tied to a ponytail at the back. His younger sister is just near his elbow level and had raven-hair like him tied in twin tails.

He smiled sadly as he recalls the time they spent together before their unfortunate demise. Pulling out the second one, it was the picture of him, Ben, Rook, Gwen, Kevin, Max and the Plumbers. Jack couldn't help but smirk as he remembered they were the ones who helped him overcome his past and moved to the future.

After putting the two pictures back in his pocket, he then looks at the Nemetrix. He only knew little to the knock-off version of the Omnitrix other than it could turn anyone into the natural predators of some of Ben's aliens.

"Perhaps it could have the same function code as my MonTrix or Ben's Omnitrix as well." Jack mutters as he began fiddling with the Nemetrix. "I may still lack many knowledge over technologies, but I still know hoe to disable and enable technologies as well."

2 hours and 35 minutes later.....

"Success!" Jack cheers as he manages to hack into the Nemetrix. "I've done it!" He said before he puts his hand over his mouth. "But now, I'm gonna sleep. Hacking takes a lot of time." He puts the Nemetrix near the table of the bed. He then laid on his bed sideways and closed his eyes as he fell asleep.

He, however, is completely unaware that the Nemetrix' symbol blinks crimson red a few times before engulfing the room in a bright red light.
