Even if Elena was chained up above Omega lock, she could feel that last battle has started. Team Prime was trying to get to the Omega lock and stop it before it cyberforms Earth. Ratchet was on his way to there and so was Optimus, while ordered Arcee, Bumblebee, and Smokescreen to get there too. Ultra Magnus, Bulkhead, and WheelJack will handle the rest and make sure no other won't activate the lock. Meanwhile, Elena tried to get herself free from her chains, but nothing.

Soon she heard a noise behind the door and Ratchet came there.

"Ratchet!"

Ratchet started to fight with Shockwave to prevent him from activating the lock. Elena meanwhile still tried to get loose, but this time she tried another way. Now with the fire element, she started to melt the chain, but it took a bit of time to melt and cut the chain by one finger, before getting one arm free and go for another one. But right then Omega lock was filled up and ready. In this Shockwave opened the low gate to have a full view of Omega lock.

"WHAT?! YOU NEVER TOLD WE'RE OUT OF SPACE!" yelled Elena.

"ELENA, HOLD YOUR BREATH!" told Ratchet.

But before Elena could do so, she notices something in her legs. They started to change. And not just legs, her arms, her chest, her head, all of her changed the look. She was in her robot form, which she got in Star Tower. That's when she realized why. To be Star supreme, her body now adopts any atmosphere either changing her to human or robot. And now that they were in Space she has turned into a robot.

"By AllSpark..." said Ratchet, since it was the first time he saw her like that.

Right then, Elena looks down and Saw Optimus down near the Omega Lock.

"DAD!"

Optimus fired on Shockwave to get him away from controls, but then Megatron came and started to fight with him.

"NO!"

Megatron ordered Shockwave to prepare the Omega lock to fire. In this, Elena tried to hurry up and free herself. She now places her hand on the chain and adds heat to her hand to melt it faster. But doing so, she started to fall, right into the pool of cyber matter. But when she falls there she stood above it like it's solid. Or it felt so first before she felt her legs sink. She tried to look where was the quickest way off when she spots Optimus and Megatron fighting. During that fight, Optimus managed to get Dark saber away from Megatron. Right before Megatron tried to order Shockwave to fire up Omega lock, the ship started to turn another side. In this Elena fall to another side of the cyber matter, before it came to normal and then back to another side.

"Who Frag is driving there?" she asked.

For that, she didn't get an answer because right then she heard more commotion above in control area. Smokescreen, Bumblebee, and Arcee came there still fighting with Starscream and his armada. But there was more. The Star Saber was there. Smokescreen went to pick it for Optimus, but he got stopped by Shockwave, but now who will get it. Elena couldn't stay look any further because she noticed that she kept sinking and she has now sunk to her waist. She tried to get out, but more she tried to move the more she sank. She had now only head left before she heard Ratchet tell Optimus to use Star saber to destroy the Omega lock to save Earth. She only could see Bumblebee coming down before she sank completely into the Cybermatter.

Under it, she felt same like been under water. She moves and breath in it. She didn't have time to ask questions before she saw blasts and after that, she saw something fall into Cybermatter. To her shock, she recognized who did. It was Bumblebee. She swam to him while he sinks down into Cybermatter. when she came to him, she finds that he got shot big time.

"No..." she rests her head on his chest. "Please...don't die...I need ...I need all of you... I love you... all of you..." while saying so she closed her optics right when one of her tears came up and came one with the cyber matter.

Then she felt a hand around her and that they both came up from cyber matter. Then there was a quick jump and loud voice yelling

"Megatron!" Elena was surprised to hear that voice for the first time. She turned around and find Megatron stabbed by Star Saber by Bumblebee "You took my voice. You won't rob, anyone of anything ever again." Elena then looked on Bumblebee and find that shot spot healed. She turned back to see Megatron right before he falls off from the Omega lock to Earth.

Elena lift up from Bumblebee and float gracefully, while Bumblebee helped Optimus up. Then they climb up to others, while Elena floats there. Others were surprised by Bumblebee to speak. Even he noticed it and was happy and hugged Ratchet.

"The Cyber matter," said Bee.

"It seems to be the only explanation," said Ratchet

"That and more," said Elena. "My tears of memory. When Bee landed, I wished him to survive like I did with Dad, Ratchet, and Arcee, my tear filled with those memories affected on Cybermatter to do my will and healed him."

"And that...new look of yours?" asked Smokescreen.

"Um..." said Elena, realizing that she had never mentioned it. "I got in Star Tower when I was declared as Star Supreme. I didn't tell you before because I didn't want to disturb you since you got separated, then together, and Beast hunting, FallStar, Predaking, Omega lock and..."

"Hahaha...We get it," said Ratchet. "You keep surprising us with more miracles." Elena smiled at that knowing that they weren't mad if not happier than ever.

Optimus informed everyone that Megatron was defeated for good. In that, he got informed that Jack and Miko secured the bridge, when Ultra Magnus, Bulkhead, and WheelJack got delayed.

Now that they had Omega lock all ready to use, Autobots decided to use it to Revive Cybertron. Bumblebee Informed Raf to come too, so he can also witness the resurrection of their planet.

Elena looked down at the Omega Lock. She closed her eyes while more tears. After many trials, she had to face it was all over. The war is finally over.

"Elena, Are you alright?" asked Arcee.

"I'm fine," said Elena and moved her tears away. "I'm good."

"You don't need to hide your emotions," said Arcee.

"It's okay. I just want to let them go in proper time," said Elena before took a deep breath. 

During the journey to Cybertron, Ratchet tried to find a way to launch the cyber matter, so it could revive Cybertron properly. But sadly, he never got a chance to study how Shockwave planned for that and considering that Cons tried to cyber form Earth, Cybertron is a much bigger planet than Earth. The power of Omega lock can be used only once. So, in this Optimus suggested that They had to launch it to the planet's core.

"Into to the heart of Primus himself," asked Ratchet.

"Let me also help," said Elena. "I believe can do it."

"Are you certain?" asked Optimus.

"I was chosen to become Star Supreme. Even AlphaStar foresaw me coming. And I was always told that Star Supreme is one with great power and I have it by love, the great power of the universe. If I can't do it then what good I am?"

Optimus looked at her. He believed she can do it. By how things looked even without element powers, she had managed to stand up in darkest hour and help others. There's no doubt about it.

"Well, what is your plan?" asked Ratchet.

"Once You launch the Omega lock into the core, I'll handle the rest," said Elena. 

Once there in Well of AllSpark, everyone was in command bridge with kids. Optimus and Ratchet were in control panel to activate the Omega lock and aim it to the core. Elena and BurnStar, however, were outside on the edge of the well ready for the second phase. Once Ratchet activated the Omega lock, he used all its power to the core, til Omega lock shut down.

Everyone started to wait what will happen now.

Elena looked on BurnStar to see if she is ready. She nodded for that  In this Elena spread all the items which hold Star element, while she holds the music box.

BurnStar created violin by flames and started playing it, while Elena opened the music box, where four lights came out. They reveal themselves as AlphaStar, LightStar, PeaceStar, and BrightStar.

https://youtu.be/ttZZGH-7_50

AlphaStar:
Now when the world is shadowed and dark

LightStar:
Now when the sky is empty of stars

PeaceStar:
Now when the world is wrapped in sleep

Alpha/Light:
In a quiet endless and deep

BrightStar:
In the silence of the night

After this Elena look on her hand, which started glow in white. She moved crossed on the items of elements and from each of them came out a spirit of Predacon of the element.

All four:
Far off in the distance
A fire comes to life
A flicker of a flame breaks through the dark
Burning soft and bright
Dancing with the light
Awakening the Heavens and the Earth

After this, Elena moved her hand ordering each of them to go across the Cybertron. Each spirit spread into eight directions either flying or running and while doing so, a bright blue light started to glow under them following them in everywhere in Cybertron.

All four:
Far across the ocean
A flame is rising high
Breaking through the shadows and the dark
Shining in the night
Rising with the light
Here to wake the Heavens and the Earth

While so, BurnStar armor changed into her coronation dress while kept playing the violin. Elena looked on the around seeing life returning to Cybertron when she notices that former Stars were going somewhere, in which she started to follow them.

LightStar:
Now as the light starts to rise

BrightStar:
Now as the day opens wide

PeaceStar:
Now as the dreams slips away
You wake to the day

Peace/Bright:
You wake to the light

Then AlphaStar and LightStar raised their hand to ask Elena took hold on them and follow along.

LightStar:
Here as your dream falls away

AlphaStar:
Feel as the dark turns to Day

LightStar:
Leave the shadows behind

AlphaStar:
And the dream called in blind

Alpha/Light:
Turn into the light

They soon spin her around in which Elena got her Star Dress in her robots form, while Spirits of Elements started to return back to the spot they started.

All four:
Far off in the distance
A fire comes to life
A flicker of a flame breaks through the dark
Burning soft and bright
Dancing with the light
Awakening the Heavens and the Earth

Then all element spirits went down to the well of AllSpark. And by their shining light, Elena knew where they were heading and followed them from the top.

All four:
Far across the ocean
A flame is rising high
Breaking through the shadows and the dark
Shining in the night
Rising with the light
Here to wake the Heavens and the Earth

The light end in one place few miles away from Well. There Elena knew what to do and summoned something to come under the ground.

All four:
Far off in the distance
A fire comes to life
A flicker of a flame breaks through the dark
Burning soft and bright
Dancing with the light
Awakening the Heavens and the Earth

From ground started to appear Star Tower back to its place, but this also with few changes. Seen it coming up, impressed everyone in the ship and made Optimus smile proudly to his daughter.

All four:
Far across the ocean
A flame is rising high
Breaking through the shadows and the dark
Shining in the night
Rising with the light
Here to wake the Heavens and the Earth

The former Star started to disappear into the Star Tower until there was only left Elena and BurnStar. Elena fly up and looked over to the horizon, where the sun is supposed to rise.

Elena:
Here to wake the Heavens and the Earth
To light

While singing the last line, she raised her hands, while Sun started to shine brightly for the first time after so long in Cybertron.

Elena smiled while seeing the how life was back in Cybertron. This will be her new home. Although it was still a bit of mess, it will come back to itself before the war. But for that she knew there will be one thing to do first, which will be a sad one; to say goodbye. 

Back on Earth in Base, it was obvious that Cybertron needs to be rebuilt again. And even if they now had their home back, it hurt to leave their new home and family. Like always, goodbye is the saddest thing. Elena looked far how Arcee, Bumblebee, and Bulkhead had to say goodbye to Jack, Raf, and Miko. It's wasn't easy for them, especially for them. BurnStar came to her.

"Everything okay?" she asked.

"I'm okay," said Elena. "It's just...well...you know..."

"If you ask me, I say you can come here whenever you want," said BurnStar. "This is, after all, your home too."

"I know," said Elena. "But my home is where my family is. And they are my family now," she said meaning Autobots. Then she looked down and place her hands front of her face. She closed her eyes and let tears fall from her eyes. BurnStar just smiled a bit before went to Smokescreen.

When others had said their goodbye's, Elena went to Jack, Raff, Miko, June and Agent Fowler. Kids didn't have much to say. In this Elena showed three Shining Stars.

"I want you to have these," she said to them. Each of them picks one. "That way even if time goes by, I'll be in contact with you. You could say it's like Star video chat or something," she said while tried to smile. Kids tried to smile to her too, but they broke to cry, especially Miko and Raff. All three came close to Elena and hugged, while she hugged back them, still smiling kindly, while more tears flow from her eyes. Luckily those tears were ordinary ones and not special ones, it would be lots of waste. After hugging them, Elena hugged June and after that Agent Fowler. Yes, even he hugged her.

"Your father will be so proud of you," he said meaning her real father. She knew this and let more ordinary tears fall.

Take the wave now and know that you're free,
Turn your back on the land face the sea,
Face the wind now so wild and so strong,
When you think of me,
Wave to me and send me a song.

After saying her goodbyes she started to walk away from them to Optimus.

Don't look back when you reach the new shore,
Don't forget what you're leaving me for,
Don't forget when you're missing me so,
Love must never hold,
Never hold tight but let go.

While walking to him, her outfit turns into her Star dress, before she jumps on his shoulder.

Oh, the nights will be long,
When I'm not in your arms,
But I'll be in your song, That you sing to me, across the sea.
Somehow, someday, you will be far away,
So far from me and maybe one day,
I will follow you,
And all you do,
'Til then, send me a song.

Everyone has passed through the portal, except Ratchet who decided to stay on Earth. Elena and Optimus looked at their friends and family one last time before they passed through the portal.

When the sun sets the water on fire,
When the wind swells the sails of your hire,
Let the call of the bird on the wind,
Calm your sadness and loneliness,
And then start to sing to me,
I will sing to you,
If you promise to send me a song.

The portal took them all into the ship from which they took the space bridge and there to Cybertron. during the travel, Elena looked when Earth left behind. Then she felt a big hand on her shoulder and look up finding, Optimus, Arcee, and Bumblebee near her. She smiled to them and hugged the one of them who was close her, which was Bumblebee. Optimus and Arcee smiled at her before looked each other and leaned on each other.

I walk by the shore and I hear,
Hear your song come so faint,
And so clear,
And I catch it, a breath on the wind,
And I smile and I sing you a song,
I will send you a song...
I will sing you a song,
I will sing to you...

Once in Cybertron and out of the ship, Elena looks up the to the bright sky. Then she looked on the new Star Tower and starts run inside to see what new it will hold but in middle of the way she turns around and looks on those 'bots she loved most raised her hand to ask them to follow her in.

If you promise to send me a song
