WHAT IS THAT METAL MONSTROSITY

And also WHO ARE ANY OF THESE CHARACTERS? I want to imagine this but I can't when I don't know who any of them are

I'm pretty sure only one of then is a good person

IM SORRY IS THAT MEGATRON

HE WOULD NOT TEAM UP WITH MEGATRON

Why would he team up with Megatron?

...so the wiki is now DeviantArt 2.0?

Great
