A Blast Line is a mark that if you go past it you are Koed and also the line that appears when you get Koed in Super Smash Bros., Super Smash Bros. Melee, and Super Smash Bros. Brawl. Every time a character touches a blast line it is a KO. Blast lines are on all sides but the type of KO varies. Blast lines are invisible and only appear if a character or enemy (Brawl only) got normal Koed (A KO to the side of the stage) A Blast line is colorful. The color varies on the type of player. CPUs have a white blast line. Player 1 is red, Player 2 is blue, Player 3 is green, Player 4 is yellow.
