Who remembers this:

It can only be a PLUS, like Gon in Tekken, or any guest in SoulCalibur

DOnt like them ? Dont play them

I rented that.  That game and the Double Dragon fighting game were the two fighters I could never find in stores to buy.

I loved that game..me and my bro played the hell out of it

If we end up not getting a stellar roster of actual TMNT-characters then it sure as hell is NOT a plus.

Lucky.  Rental places were great during the SNES era for me because they always had awesome games that I could never find in stores.  I'd have that game and the Double Dragon one if I could have found them for sale at the time.

Your jumping the gun a little to early. Just be more patient. We haven't seen a single villain in the roster yet. This isn't Nintendo world this is TMNT world they will have more characters. Though since this is a first game in the series you shouldn't expect more than 22 characters at best. I wouldn't be surprised if it was only 8 a side.

Considering that there is no one source my vote on other characters are
Shredder
a Triceraton
Karai
Krang
Rock Steady
& or Bepop
?
?

lol....my parents would randomly by me and my brother games...and this was one of them..I miss Battletoads too :(

I am a little peeved that they chose to put emphasis on the rabbids over actual TMNT characters at this point. Certainly there are going to be more, i mean, they haven't even put Karai in yet, she at least is a shoe-in.

My interest won't be significantly effected until closer to launch, when/if we see the final roster.

And i doubt Krang will make it, since he only existed in the "Old Cartoon" continuity, the one continuity that didn't have Utroms. I don't know if they want to incorporate characters that only existed in one continuity or not

The Turtles have been in Archie Comics.

Just sayin'...
