falco can laser cancel, look at the samus discussion and find missile canceling.
falco can dash attack cancel, look at the snake discussion and find snake sliding
falco has a terrible verticle recovery, never use up b unless you need to recover vertically. if you can, use side b instead.
falcos side b is a spike, so if someone is pursewing you affstage, give them something to regret.
falcos dair is a strong spike, but only early in the animation. after that it sends opponents off to the side.
falcos reflector has a VERY high rate to trip your opponents. use it to screw over their approach.
