How are the GBA versions of the new TMNT games and what characters are in..
 

..Mutant Melee, I was thinking of maybe buying some of these games Any advice? Thanks.

well i dont know about the new GBA games.....but the Mutant Melee game is alright, its pretty fun playing through it, but if i remember right, it gets kind of frustrating at a few points, and after u get through all the levels u are just relieved to just be done, and don't feel like going back through and beating the levels 100%, (for example, u have to beat the level with so much life left) which again gets frustrating......but i would say its atleast worth the cost of the game....just my 2 cents

Are there any hidden playable characters in GBA and DS new toon games? And what are all the characters that appear? I really like Leatherhead and Usagi and wonder if they appear in any of the games.

No, there's no hidden playable characters as far as I recall when it comes to the GBA and DS games.

Well... Leatherhead does appear in the DS TMNT game. As a boss fight and in a level or two where he teams up with the TMNT. Usagi... sadly does not appear in any of the three games.

The first GBA game does have a level where you team up with Casey Jones against the Purple Dragon though. The second game, as far as I recall, doesn't have the TMNT meet up with any characters for help. The third game, for the DS, however does have a quite a bit of teaming up to do. Splinter, Leatherhead and Karai at various points throughout the game.

As for Mutant Melee... It's been quite some time since I played it, but I think the playable characters were basically the TMNT of course, Splinter, Casey, a few different versions of April, two different versions of Shredder, Oroku Saki, Hun and few variations on Foot Ninja.

What bosses are in the gba and ds games? I can't seem to find a DS out here since they are all sold out and haven't been able to play my games.
