The Driller or The Dweller just seems like the names Hasbro would use. However would they align it with a faction? It doesn't seem as sentient as Skorpinok, Ravage and Laserbeak.
I kind of like the name The Dweller. Gives it a bit of a H.P. Lovecraft vibe given the size and shape of the robot.
I dunno it definalty looks like it was going for Prime in that trailer. It might even be some kind of mutated bot given where the comic says they find it.
just a little preview budd, watch the last thirty YouTube - Transformers DOTM Theatrical Trailer (3D Edit)‏
Look closely at the driller as optimus 'ramps' into him, that's his face as I can clearly see his two big red eyes, so it really is a robotic tremor like I thought.
they might name it razor snake, or destruction worm or something. i like the first one because the way it wrapped itself around the building in the trailer reminds me of a boa constrictor.
