For future sequels
 

What villainous characters from the TMNT mythos do you feel could be the main antagonists for future installments?

Triceratrons/Federations, Bishop maybe....Savanti Romero....it could be a re-do of 3....*shrugs*

1st sequel: Baxter Stockman, Karai
2nd Sequel: Rat King, Shredder

I actually really like the concept of brand new baddies mixing with established baddies, like how we have Max Winters & the monsters and Karai & the Foot in this movie.

It's already been hinted that a sequel could have something to do with Shredder. If that happened, I'd want that to be the extent of established baddies.

In order of preference:

1. Rat King
2. Rat King
3. Rat King

i don't think they would do one with the Triceratons/Federation because they have the triceraton breathing helmet in the picture and the Federation blaster hangin up by the light in that Trophy Room picture from the new movie

bishop and rat king could be good, but they would have to be more than them 2 in the movie (atleast i think so), and it would be pretty cool to see a sequal with shredder, then then again, not by himself, like roseangelo said, i like the idea of introducing new bad guys with the old ones (it allows the TMNT universe to expand for more new wonderful stories)

But, what about Rat King? :-?

I've always liked the idea of an evil Slash...more pumped up, more sinister looking...like in the Kevin Eastman Artobiography where he an idea for a fourth live action tmnt was a evil turtle but this was named Kirby (in the inside of the cover is where he various/different drawings of the character).

I was thinking for the next movie, they could use a resurrected Shredder, who could be explained as being alive again as the result of black magic. And they could introduce Baxter Stockman as Shredder's lackey, and the return of Tatsu as Shredder's second-in-command. This movie takes place within the TMNT movie universe, technically. so Tatsu should still be looming somewhere. I suppose they could modify him to include a personality similar to Hun's.

What do you mean modify his character the best part of it is all the grunting he does lol

Baxter is too good a villian to be a lackey. I'd say, for the second movie, make Baxter the main villian, like maybe he was hired by Karai to steal the technology needed to resurect the Shredder.

I'd love to see Leatherhead. Heck, maybe Shredder isn't dead and he somehow survived. But Leatherhead needs to be in the next work since he shares the same origin.

My thoughts exactly. He should also be voiced by Keith David.

Man, just thinking about Keith David doing his voice sends chills up my spine. That would be so awesome. Heh, maybe we can persuade Mr. Munroe.

You're right, you hold him down and I'll get the gasoline.

I would like to see Baxter and the Mousers in a movie since they weren't in the original trilogy or the new movie. I suspect Karai and the Foot will stick around for a sequal as well.

Leatherhead would be cool, although he'd end up more of a good guy than a villain.

Thats exactly what I'm hoping for.

leatherhead was only a bad guy in the original cartoon (as far as i know of), otherwise he was an ally

Leatherhead was borderline between enemy and ally in the Mirage books. While he didn't intend to do wrong, his anger was too uncontrollable to keep him from hurting innocents. While similarly conceived in 2K3, it wasn't played up very well (hardly noticeable if you ask me).

Anyhow, yeah. Leatherhead and Rat King are both characters I'd like to see on the big screen. But, I hope not together. We'd need a mastermind thrown in for variety.

He's pretty much neutral with the TMNT, right now they seem to be on good terms.

Yeah, the Rat King and Leatherhead do need some movie treatment, but your'e right, not together.
