Big Bertha is Chibi-Robo's Final Smash in Super Smash Bros. Global Apocalypse. When used, the camera focuses on Chibi-Robo, as it slowly pulls out of its head a huge missile blaster. Any character in a long horizontal distance in front of Chibi-Robo stun immediately. Then, Chibi-Robo fires a huge missile, which covers most of the screen, horizontally in front of him, damaging anyone it hits and making a huge explosion. Any opponent hit by the missile as it travels is inflicted 25% damage and powerful knockback, whereas the explosion causes 45% damage and a nearly instant KO.
