YOU ARE ALL WRONG...
Fox is a clone of Falco, who is a clone of Fox, who would be a clone of Falco, but Fox was in SSB first. BUT...Fox is a clone of Falco because they share the same moves, but Fox is a brown fox and Falco is a blue falcon. THUS... Falco is a clone of Krystal because he is blue, but Krystal isnt in Brawl, and she isnt a bird...MAKING HER a clone of Fox, because she is a fox(?). Falco would be left out as an anthropomorphic bird, not relating to the Starfox team, like Slippy. ON THE OTHER HAND... Slippy could be a clone of Falco, being an amphibian unlike other SF members, like Falco being the only bird. ALTHOUGH...Slippy could also be a clone of Krystal, because blue-furred animals are unrealistic, like the fact of Slippy resembling a Muppet. Krystal, though, does NOT resemble a muppet, and thus must be a clone of Wolf, having no other subjects left. Wolf is a brawler, and Krystal isnt...BUT Fox and Falco are, making Wolf a POSSIBLE clone. Not spending off-time with the team calling saying "Hey Fox, wanna go see Dragon Wars at my place" or "Sup homes. Can ya spare a cup of sugar?" would make him like them...but what do I know? Im just a Filipeno.
