Elena twists and turned in her bed. She was seeing something horrible in her dreams. the army of undead robots. No, those were Cybertronians dead. And then there was earth in chaos. Led by...Megatron.

Elena screams out loud realizing it was a dream. But she knew what that was. It has happened a few times already. The dreams were warnings what could be coming. She got up run out of the door that leads to quarters of Optimus.

"Optimus. That stuff Arcee had... It..."

"Calm down. What is it?" he said and came near her. Then Silver came and showed the code of purple liquid and compared to it on Star files on the code of Dark energon.

"You knew this, did you?" asked Elena from Silver.

"Stars can't stand the dark Energon," explained Optimus. "As guides for good and wisdom they are pure and can't stand any dark power."

"But how could it..." asked Elena before they heard fighting. they to the command center to find Ratchet fighting some creature that once was one of his tools. It was so close on Ratchet until Optimus blasted and finished it by stepping on it.

There was no doubt what made it happen. And how they got life signal of Cliffjumper. And it came obvious that is was Megatron who brought it to the earth.

When others came back with kids, Optimus and Ratchet were going out for investigating one place.

"Let me come with you," said Elena.

"It could be dangerous," said Ratchet when he prepared the ground bridge.

"I'm only 30% of living metal. And what could be a possibility that I get near the..." looks on others. "...danger. I got force shield to protect myself."

Optimus knew why Elena didn't mention dark energon. Others were near and if they hear where they're going, they will go too. "Very well," he said. Elena changed her outfit to black top, black jeans and black boots, with the fingerless gloves.

"Silver, You'll in charge on Star computer," she said before she left with Optimus and Ratchet.

While they walked Ratchet asked where they were going. Optimus told about one battlefield which happened during the time when few started to move their Energon supplies into other planets, which why there were some battles in the earth. And it seems like Megatron knew it too.

"You think he knows about me?" asked Elena.

"It could be less possible," said Ratchet. "Stars knew how to hide their life signals during the war."

"But it could possible he will learn your existence sooner or later," said Optimus.

Soon they arrived at the ancient battlefield. There was corpse remind from the brutal end of the battle.

"For the first time in my life, Optimus. I hope you were wrong," admit Ratchet.

Then Megatron came and by so far distance Elena could some reason feel the dark energon on him.

"I know why you are here, Megatron."

"Hardly surprises me, Optimus. After all, we have been to this for a long time" said Megatron. "And now your has come to an end." Then he throws the shard of dark energon to the ground in which raised the undead army.

"By the Allspark..." said Ratchet.

Elena holds tightly on Optimus. It was just as in her dream. And for some reason, She started to feel dizzy.

"Behold the power of dark energon!" roared Megatron while the army got near them. "Destroy them!"

By each step the undead army got near them, Elena was getting more and dizzier if not also feeling unwell.

"Ratchet, retreat. Bridge yourself back to base," said Optimus. "And take Elena with you."

"No.," said Ratchet. "I shall stand with you, Optimus. You may require a medic when this is over with."

Before Optimus continued fighting, he left Elena to nearest cliff, knowing that they won't go on her.

Elena was feeling weaker, that she had to lay down and watch how Optimus and Ratchet kept fighting. Perhaps she forgot she is Star already. Maybe her body is accepting even the weaknesses she must have. She even notices how it was even effecting on Optimus and Ratchet.

They kept fighting until undead army started getting to Optimus first.

"Optimus!" yelled Ratchet before they got him too.

"No..." whispered Elena. Even her voice was getting weaker. "Please... Don't die..." she said before her eyes closed and one tear fall from her optics.

Then from the pile of undead Optimus got rid of them and help ratchet out. Ratchet got an arm broken, but he kept fighting. Optimus kept fighting until he got near the cliff where Megatron was standing and started the climb to him before he transformed and fly away. Optimus tried to fire but missed. Then he helps Ratchet up and looks down into pieces of the former army of undead.

"If this wasn't Megatron's in-game, then what is?" asked Ratchet.

They came back for Elena to find her very weak.

"Silver, open the ground bridge," informed Optimus to the base. "Elena is not well."

In the base when Optimus help with Ratchet's arm, Silver was checking Elena. Since Elena was half human and robot. Silver had taken her health. plus as a former Star, she had studied the human body, so she knew how to keep balance.

In that time Jack didn't want to part of the situation since they almost got killed. Autobots respected him his wish and let him go. Right, when he passed through the ground bridge, Silver asked Optimus.

"What is it?" he asked. silver pushed container, in which they had to collect energon for medical issues. Optimus pick it up before he realizes what she meant. Elena needed his energon. And he knew why. Those same words ring in his mind.

"ARE YOU OUT OF YOUR MIND?"

"All I need is to fill the parts with energon and CNA sample to the impacts to..."

"No no no! You had done enough."

"She will understand."

"Optimus, Please I had to do this!"

"Finish the operation"

"Optimus..."

"NOW..."

He used the container collect his energon making every surprised everyone.

"Optimus.." said Ratchet.

Before anyone could say anything else Silver already took the container and used it to heal Elena. There was bright light before the monitors with her life signal showed she was going to recover.

Raf and Miko went to look her when she started open her eyes.

"What happened?" she asked.

"Don't you remember?" asked Raf.

Elena tried to remember before she remembers the last thing she saw.

"OPTIMUS! RATCHET!"

"We're here," said Ratchet. "In one piece."

Seen them, Elena sighed for relief. After that, Silver pushed her back to rest and recommended her to do so until morning.

Soon when Bulkhead and Bumblebee went take Miko and Raf to home Elena was still resting in sickbay. Even if she was so small she had got used to rest on a berth. Then she notices someone coming to her. It was Arcee.

"Everything okay?" she asked.

"Just too tired," answered Elena with a smile.

"You really scared us."

"Sorry. I thought since I'm mostly still human I..."

"You would have died then," said Arcee.

Elena looks at her confusedly.

"Energon is not good for humans," said Arcee.

"Then the dark energon would have..." said Elena before she stopped. that thing idea really scared her.

"You need to rest," said Arcee before she left to her resting chamber.

When she closed the door many questions fill her just happened there? Why did Silver ask Energon to heal Elena? And Why Optimus? Could it be that Elena is becoming Star for real, even has a human? She couldn't think any answer to them now. She has to ask later. Right, there was another thing that worried her. Jack Darby.
