Falco Phantasm is one of Falco's many moves in Super Smash Bros. Melee. It is executed by tilting the Control Stick to the side, then pressing the B Button. Falco will proceed to race accross the screen at light speed, damaging any player that Falco runs into. Although the attack is not that powerful, it is the perfect move for getting through large amounts of enemies. However, using this attack near an edge is dangerous, considering that he will just run off the edge. A similar move is Fox's Fox Illusion attack. Try experimenting with the move in Slo-Mo Melee.
