PK Flash is Ness's Standard Special Move in Super Smash Bros. Global Apocalypse. It is a chargable move. When performed, a sphere of green light appears above Ness. As the attack button is held, the sphere moves downwards and increases in power, until the attack button is released or until it is fully charged, it explodes. The move is very powerful in terms of damage and knockback, but hard to control. It can be slightly controled horizontally and vertically.
