Thunder is Pikachu's Down Special Move in Super Smash Bros. Global Apocalypse. It has the same function from SSBB. Pikachu summons a cloud high above him, which fires a lightning and strikes vertically at Pikachu. Pikachu does not receive any damage from the attack. Thunder deals 14% and has the most knockback of any other attack of Pikachu's.
