Set to launch on December 7 for Nintendo Switch, Super Smash Bros. Ultimate will include every single fighter ever featured in the series’ nearly two-decade run, making it one of the biggest crossover events in gaming history. Fans can enjoy returning favorites like Pikachu, Pikachu Libre, Jigglypuff, Pichu, Lucario, Greninja and Pokémon Trainer, who fights by making commands to Squirtle, Ivysaur and Charizard. There are also numerous Poké Ball items that players can use to their advantage, including Mimikyu:
Mimikyu drags a nearby opponent under its rag and attacks them! The opponent cannot move while captured by Mimikyu, and if they end up with more than 100% damage after the attack, they’ll be instantly KO’d.
