Start-up time, commonly referred to as "start-up lag", is the delay that a character has before the first hitbox of an attack comes out to hit the opponent. In essence, this is the time between pressing the button and getting a result. Fox and Falco's Shine (Melee only), as well as Jigglypuff's Rest, have the least start-up time of any move at 1 frame. The move with the most start-up lag in the games is Ganondorf's up tilt. Flinching during startup time will prevent the move from being executed.
