Editing Crazy Hand (section)

=== Super Smash Bros. Ultimate ===
Crazy Hand returns as a boss in ''Super Smash Bros. Ultimate'', appearing in various game modes with expanded roles and unique mechanics.

In Classic Mode, Crazy Hand fights alongside Master Hand when the player's intensity level reaches 7.0 or higher. For certain characters, such as Falco and Ken, Crazy Hand serves as the final boss, with Master Hand joining him only at higher difficulties. This adds a layer of variability depending on the fighter's route.

In Adventure Mode: World of Light, Crazy Hand is prominently featured as a subordinate of [[Dharkon]], [[Galeem|Galeem's]] dark counterpart. Multiple Crazy Hands appear following Galeem's initial defeat, acting as bosses throughout the Dark Realm. Crazy Hand is fought three times in the Dark Realm—each guarding one of the pathways into its subareas—and twice more during The Final Battle.

In the game's true ending, Crazy Hand and Master Hand are freed from Dharkon's control. They assist the player by creating a giant rift using ''Static Discharge'', allowing the player to enter and destroy 50 puppet fighters powered by Dharkon and Galeem. This freedom suggests that, like the fighters, Crazy Hand was originally captured and cloned into a controllable puppet before the events of ''World of Light''.

Crazy Hand introduces a new mechanic in this game, where he can face either direction (left or right), which he combines with snapping his fingers to teleport around the stage.

In addition to gameplay appearances, Crazy Hand is represented as an Ace-class Neutral-type primary spirit. This spirit, which allows three support slots, is earned by defeating Crazy Hand in the final battle of ''World of Light''. It is among the most powerful spirits in the game, making it highly sought after by players.
