Dude on the contrary to popular beleif they all have the same reach in turtles in time. That was for Ninja TipTup. And for TMNTGUY4EVER if you still cant beat it go to options and lower the level and raise the rest. I've got the guide here and will give you everyone power rating so you will know who is best to use. (note: this is on a scale of 1-
Leonardo:
Normal Attack:5
Rush Attack:5
Special Technique:5
Defense:5
Speed:5
Mike:
Normal Attack:6
Rush Attack:4
Special Technique:6
Defense:6
Speed:4
Donatello
Normal Attack:5
Rush Attack:5
Special Technique:7
Defense:4
Speed:3
Raphael
Normal Attack:4
Rush Attack:8
Special Technique:8
Defense:3
Speed:7
In my opinion, if you can avoid getting hit a lot, raph is the best, but in your situation i would recommend Mike.
