if your confused let me help you out:
Fox: Fast running,fast falling character. His strengths are all above in the previous posts. His blaster does about 1-2% each shot, no launch power.
Falco: A little slower than Fox, but can jump higher than anyone (except maybe yoshi, but 2 jumps+ recovery tops yoshis jumps), check the falco guide for more. His blaster does 1-3% with a little launch power.
Wolf: Just a smige slower than Falco. He can take more damage then Fox and Falco, and i think deals out a little more damage on a hit-to-hit basis. his side special goes at an angle, and his up special has a shorter range then the others, but when used offensively, it chains hits. His blaster does about 4-6%. When he uses his blaster next to someone, it hits em for 2-4% cuz of a knife on his gun.
*also, a note on the down special. Fox and wolf crouch and hold thier position, and falco throws his forward like a boomerang. All of thier reflectors shares a common thing: If it is used and an enemy is standing next to the user, the enemy will get launched a little bit. this is useful on the lower sides of a stage, because it knocks the enemy away, and a recovery move will save you, and you can still kill the other guy.
Hope this helps you decide :)
