Your POV 

I was typing into a computer. I was currently alone in my classroom, which was like an auditorium, but more slanted. I was currently filling in for 'Primus', who is a teacher in this world. Unicron aswell. I also had to make up a power for me, which was easy once I saw what the power of all Bots and Cons were in this world: Cybertronian. It was actualy a somewhat common power really. 

It allows us to summon weapons and armor of our bot forms, and if the user try hard enough, they can summon and become their Cybertronian Form, which can do everything a cybertronian from my world can do. But a drawback is that it takes extreme concentration, and if their Cybertronian Form takes enough damage, it will revert them back to their human form, which will be searverly hurt. 

I found a way to alter my holoform so my left arm can become my true arm, replacing the 'human' arm. I can also alter my right hand and forearm into my missile launcher & claw combo. I remember when they used to be normal, well, there really is no 'normal' for my kind of cybertronians. We come in all shapes and sizes. A rare select few can even combine into a bigger cybertronian and combine their minds. 

Granted not all are sane, or the combined mode is standing on two feet. Take Devastator for example. A mobile Anti Dat Shit form. With enough firepower to level a small army, and not to mention the votex grinder, Devastator could destroy a city, if he wasnt just a mindless beast that could only follow simple orders. At least there's the fact that any group of of constructicons could combine to form him. 

Granted at least some things need to be met to form him. You need a wheelbot like Scavenger or Demolisher along with a mixer like Mixmaster or Vulture to form the vortex grinder. There also needs to be sufficent mass to form the arms and legs. Once those are met, you got yourself Devastator. Speaking of the Constructicons, this world has them, but they have not formed their team yet, or call themselves Constucticons. 

I typed in a response to an email when the bell rang. Here comes the class. They are the Autobots and Decepticons. They have not formed sub groups like the Dinobots and Combaticons yet, so I can have some breathing room with my past. I watched as they trickled in, getting to their seats. Some gossiped about things while some pointed me out to their friends. I looked at the note Primus left for me. 

'They can have a free day. Just make sure they dont get to loud. Oh, dont forget to fill out attendance.' It said. I looked from it to the computer then to class as the bell rang. "Alright. It says here you can have a free day, but first let me get attendance out of the way." I said before doing attendance. Everyone answered when I called their name, so no problems there. I looked to the computer as I started browsing the web. 

"Mr. Substitute, what's your name?" One asked. I turned to see that it was this world's Bumblebee who asked. "I'm Mr. Trench." I said. "Okay." She said before going back to talking with her friends. I went back to browsing. I then overheard a comversation. "What does the school website say about him?" Megatrona asked. "Says here he's a substitute new teacher. Has the Cybertronian power like us." Starscream said. 

"Anything on what his Cybertronian form is and alt mode?" Megs asked. "No." Soundwave deadpanned. I was then called on my new phone. "Hello." I answered. "Mr. Trench, our teachers are all occupied with classes. If we get another teacher to take over the class, can you investigate a strange energy reading at the abandoned steel mill out of city?" Ozpina asked. "Sure thing. I'll go there now." I replied. I stood up, the door opening. 

"Mr. Trench, where are you going?" Bumblebee asked. "Dont worry about it kid." I said, walking out. Time to do my first mission.
