In Super Smash Bros. Ultimate, Mimikyu that appear from Poké Balls use Let's Snuggle Forever on any opponent who gets too close to it. Unlike its depiction in the core seriesgames, Mimikyu grabs its target instead of jumping on top of it. If the target is at 100% damage or more, they will be instantly knocked out, and Mimikyu will leave behind its disguise and presumably depart afterwards.
Mimikyu strikes a series of synchronized poses with its Trainer to build Z-Power. It then jumps towards its opponent, expands the size of its disguise, and lands over the opponent, covering them. While it is inside its rag, Mimikyu attacks the opponent.
