Barrel Bash is Donkey Kong's Final Smash in Super Smash Bros. Global Apocalypse. Donkey Kong pulls out a giant DK Barrel and trapps opponents in it. He will then start punching it with very fast and powerful punches, until he delivers the final punch, ultimately destroying the barrel and delivering high knockback to those who where trapped within it, as well as great damage. However, in order to accomplish his Final Smash, players must focus on 1 opponent in order to trap him. Then, two random buttons will appear on-screen and the human player must press them repeatedly in order for Donkey Kong to continue punching the barrel. The faster and the more correct he inputs the commands, the greater damage Donkey Kong delivers.
