Ultra Magnus, Prowl and Blaster. I know you said 3 but if Blaster is in, we need 2 new little guys for the kids so I say bring on Eject and Rewind too.
um sorry but i think there is already a thread made about this anyways i think tital wave, rodimus and omega supreme
I have two out of the three you mentioned first one being cliffjumper, the second one is prowl and the third one being hound.
Hopefully DOTM can rape the box office and guarantee us a fourth one. Anyway: Autobots-Ultra Magnus, Inferno, Smokescreen, Alpha Trion Decepticons-Scourge(RIDesque), Onslaught, I can't think of many right now UNICRON!!!
I'd rather have a reboot. In the Reboot: Autobots: Optimus Prime, Bumblebee, Red Alert, Bulkhead, Arcee, Rodimus, Warpath and Hound. Decepticons: Megatron, Starscream, Soundwave, Lugnut, Knockout, Brawl, Thunderblast and a whole army of Vehicons. Hey I'm trying to mix it up a bit, yo!.
A G1/WW themed Grimlock that turns into a tank of some kind, a RID themed Scourge that turns into a black Peterbuilt tanker truck (have a line in the movie making reference to him as Prime's Nemesis, or somehting like that), and a RID themed Sky-Byte that turns into a WWII era bomber.
I really do NOT want a reboot. If there was an in-continuity sequel, I'd want a crew of space mercenary type Cons arrive to fill the void, kinda like the Dead Universe crew in the comics. So Galvatron, Scourge, Cyclonus, etc. Maybe new Cons inspired by some of the Pretender cast as they all had badass names. As for new bots, I don't think we need any new leader figures or young heroes (BB suits just fine) but I would perhaps have Hound, Prowl (but NOT as a police car), Cliffjumper and Trailbreaker. Just to round out some of the original cast.
I think Galvatron should be introduced as a separate character to Megatron, perhaps as the war began, Megatron had Galvatron as his apprentice and trained him, but kept the decepticon's existence secret. Galvatron escapes cybertron a couple of years after the end of TF3 and goes to earth? Spoiler this of course would be assuming the autobots return to cybertron, so they have to go back to earth. Also this is assuming Megatron dies
