Backward Somersault

The Backward Somersault (referred to as Backflip by Prima Game Guides and Crouch Jump on the official Super Mario 3D Land website, the Super Mario 3D World manual, and Super Mario Maker 2) is an advanced type of jump introduced in Super Mario 64; it has been present in every 3D Mario game since. To do this, the character must jump while crouching. The character jumps high and flips over in midair, moving backwards. The character may chain it to a Ground Pound. The character can also control the backwards horizontal distance by holding back on the Control Stick.

This move is also present in Donkey Kong 64, working as it did in Super Mario 64, though it can also go straight up and forwards.

In Super Mario Sunshine, Mario cannot crouch, but he can do it only if he sprays water, then lets go of the pump while jumping. Doing so creates a blast of water.

In Super Mario 64 DS, Luigi spins to slow his descent after performing this move.

In Super Mario 3D Land, Super Mario 3D World, and the respective game style in Super Mario Maker 2, this move must be charged up first by crouching, and it can also go straight up and forwards, like the Power Squat Jump from Super Mario Bros. 2.

In Super Mario Odyssey, Mario can do Backward Somersaults continuously if any of the shoulder buttons (,, , or ) are held.
