Roll Jump

A Roll Jump can be performed in Metroid Prime 2: Echoes to reach certain areas and items faster. It is performed by rolling off a ledge in Morph Ball form, then immediately unmorphing and doing a Space Jump, similarly to a BSJ. Sometimes, when she uses it, Samus will not make it, but will respawn on the ledge she intended to get to.

She posesses a similar ability in Metroid, where she can roll off a ledge in Morph Ball, and when she unmorphs, the Samus sprite will be in the standing pose, and she can jump once.
