Actually, noone's a clone in SSB:M. They may have the same moves, but they are totally different.
E.G.
Falco's falco phantasim is stronger, but goes a shorter distance than fox's fox flash (is taht what it's called?
The same with falco's firebird.
Also, falco jumps higher than fox, but is a bit slower.
Falco doesn't have a rapid fire for his laser gun, but it can actually push them back.
Foxs laser gun doesn't push them back, but has rapid fire.
Fox is faster than falco.
See?
