Falco (SSBM)/Up smash
Falco does a flip kick with quick startup, moderate vertical knockback, and moderate ending lag. It is significantly weaker than Fox's up smash, to the point where it isn't considered a reliable finisher under 150% unless used on a stage's top platform, even against floaty characters. It can be used in situational combos or followups after a short hop laser or a full hop double laser where both shots hit, but Falco's forward smash is often a superior followup option from that setup. It can also juggle and tech chase opponents at lower percentages, but Falco has many other vertical-hitting moves that are faster and much more reliable for those purposes, such as his shine or up tilt. Due to these reasons, the move is rarely used in Falco's metagame.
Falco's head (but not bill) is intangible from frames 1-10.
