Geno Blast is Geno's Down Special Move in Super Smash Bros. Global Apocalypse. A beam of energy slightly wider than Geno himself quickly shoots down from the skies to where Geno currently is. The beam quickly flashes between various different colors and if you pause the match with this move in play, you will see that that the beam is not merely 1 solid color, but that different strips of it are a color and that the beam spins so fast that it looks like it is only one color at a time. The attack is a bit less powerful as Pikachu's Thunder. It can deal up to 18% damage, with good knockback.
