Dynasty Warriors DS is the only thing I can think of.... Try googling it....

EDIT There is also Teenage Mutant Ninja Turtles and X-Men

 

Are there any like co-op ones?

 

lord of the ring conquest can co-op

 

You can try Jump Ultimate Stars for the DS... its is japanese, but you can find translation patches.
As far as 2 player possibilities... i can't say for sure because i haven't played it in like forever.. but i do believe it's possible.

Someone might be able to clarify that for you.

 

TMNT and X-men are co-op
