A Blast KO is a type of KO in the Super Smash Bros. series. It is the most common KO as it can happen on every Blast line.
Starting with Brawl, every character has two or no quotes they say when they get KO'd (With the exception of Jigglypuff and Mega Man).
A Blast KO will respawn you faster than a Screen or Star KO'd character, allowing for moves such as punishing.
