Mecha Hand

The Mecha Hand is a large mechanical hand modeled after Bowser's own hand that appears in New Super Mario Bros. U and New Super Luigi U. It is attached to Bowser's Airship, and it is most likely operated by Bowser Jr. The Mecha Hand is present during the intro, where it tosses Mario, Luigi, Yellow Toad, and Blue Toad into the Acorn Tree; The Mighty Cannonship (All Aboard! in New Super Luigi U), where it attempts to knock the players out of the airship; and Boarding the Airship (Bowser Jr. Showdown in New Super Luigi U), where it acts similarly to the Pillars from Super Mario World and the Incoming Chomps from Super Mario World 2: Yoshi's Island. Ultimately, the hand destroys the airship when it attempts to crush the players while they are on board.

In Mario & Luigi: Superstar Saga + Bowser's Minions, the Mecha Hand is used to bring Luigi to the Koopa Cruiser, replacing a generic-looking claw.

A smaller variant of the hand appears as one of the attachments to the Junior Clown Car in Mario Tennis Aces. Bowser Jr. uses it as part of his Special Shot.

The LEGO Super Mario "Bowser's Airship" expansion set contains a Mecha Hand mounted on one of the ship's flagpoles.
