*Y/n POV*
I was wandering around the ship like usual when I noticed Starscream limping to the top, holding a purple shard in his hands.
Y/n: There's no way he isn't up to something bad with that.
I decided to follow him, but he took off, and I couldn't keep up. So, I went back inside to tell Megatron what I saw.
Megatron: Ah, Y/N. What brings you here?
Y/n: I saw Starscream take a purple shard and fly away. Should I be concerned?
Megatron: About Starscream? Don't make me laugh! But that 'shard,' so to speak, is dark energon. It is very dangerous. Go follow him.
Y/n: ...I can't fly.
Megatron: ...True. Then use the ground bridge and make sure you recover that energon. Understand?
Y/n: Yes, sir.
I did as I was told, headed to the ground bridge, and asked one of the workers to send me to Starscream's coordinates. However, once the bridge opened and I stepped through, something felt off.
Y/n: Why is everything gray?
I quickly forgot about the atmosphere when I noticed the Autobots standing ahead of me. I charged at them and swiped-but my attack passed through them.
Y/n: What's the meaning of this?
Faint voices came from behind a rock, but before I could investigate, an undead Transformer attacked me. It threw a punch, but I, already annoyed, absorbed its arm into my body, dissolving it in minutes and growing a foot taller in the process.
Y/n: That was a nice meal.
*3rd Person POV*
Y/n approached the rocks where Miko, Raph, and Jack were hiding.
Raph: Guys? It's coming closer!
Miko: What are we waiting for? RUN!
They tried to escape, but Y/n swiftly captured them, lifting them up to face level.
Y/n: What are you humans doing here?
Miko: To watch the Autobots kick your butt!
Jack: Wh-what she meant to say was we got stuck here by accident!
Y/n: What do you mean, stuck?
Raph: You see, we're currently not on the physical plane but in some shadow realm of reality!
Y/n: ...
Miko: Different dimension.
Y/n: Oh. I guess I got what I needed, then.
Y/n put the three down as they looked around the dark reality.
Raph: You're letting us go?
Y/n: Yes.
Jack: Why would you do that? I mean, we're on the Autobots' side.
Miko: Shut it, Jack, before you make them change their mind!
Y/n: You're not a threat, so I won't kill you unlawfully.
Raph: But you're a Decepticon?
Y/n: No, I'm a slime. I help the Decepticons, but I am not one of them. I was sent here to collect Starscream, but it doesn't look like that'll happen anytime soon.
Jack: Isn't he your ally?
Y/n: He's been acting out lately.
Raph: What do you me-
Raph was cut off as Y/n covered his mouth with a tendril, preventing him from speaking. The group looked at Y/n, who appeared stressed.
Miko: Hey! What was that for?!
Y/n: Last time I answered questions like a friend, I got betrayed. I don't want that to happen again.
Jack: Was it Arcee?
Y/n stayed silent.
Jack: Yeah, she's pretty ruthless when it comes to enemies.
Y/n released Raph, who gasped for air. An awkward silence fell over the group as they just stared at each other, saying nothing. Suddenly, Starscream emerged from a ground bridge, followed by the Autobots.
Raph: A tear opened! Come on, guys, let's go through!
Miko: Hello? Do you not see Starscream waiting to catch us?!
Y/n moved toward the tear, sending out a tendril to crash Starscream into a wall, knocking him unconscious. The group stared in awe.
Y/n: Why do you have to be so much trouble, Starscream?
The humans ran toward the tear and into the Autobots, who Y/n hadn't noticed until now.
Y/n: ARCEE, YOU GLITCH!
Bulkhead: Geez, talk about a grudge.
Y/n advanced on the group, but Optimus Prime jumped in front, stopping Y/n in their tracks.
Optimus: Y/n, stand down. You don't have to side with the Decepticons! Arcee has told me everything. You owe them nothing!
Y/n: What do you mean, I owe them nothing? They saved my life, fed me, took care of me, and gave me the name you call me by now! And I owe them nothing?!
Optimus: You have yet to see the world, Y/n! This planet is beautiful and full of life. The Decepticons are using you to help destroy it!
Y/n: Using me? Megatron wouldn't do that, right? Prime, I've been here since the beginning. I know this world is full of life, but humans have taken that away! How many species have gone extinct because of humanity's greed?
Optimus: ...
Y/n: They've killed so much, Optimus. I don't want to destroy this planet, just ensure the humans get what they deserve!
Optimus: You can do that another way. Let me help you. I know what it's like to feel like there's only one path.
Optimus relaxed and extended his hand toward Y/n. Y/n reached out as well, and-
