Fox, Falco and Wolf ARE almost the same
Ya, about that... NO THEY AREN'T!!!!!! sorry, lost my temper 4 a second... alright then, well, about how they are different:
1fox can't spike
2wolf's blaster stuns, and the claw thing on it does damage at close range
3wolf's </>b goes up in the air
4wolf's landmaster is shorter time-wise, but more powerful I think
5I don't think wolf can infinite his a combo and fox and falco can
6falco's reflector is a projectile
7falco and wolfs laser require you to wait longer than fox's in between blasts
There are more differences but I am too lazy to complete this, if someone else wants to, feel free...
