||The Morph Ball is a Metroid trademark. After finding this item Samus can roll into a ball and access narrow passages that she could not otherwise access. There are a number of upgrades Samus finds for the Morph Ball.
||Allows Samus to break certain objects, activate some devices, like Morph Ball Sockets, and damage enemies. The force from the bomb can also catapult her up a short distance in Morph Ball form. Samus has an infinite number of these, but can only use three every few seconds.
||This item allows Samus to build up energy and release it in Morph Ball form, resulting in a burst of speed that can, when applied correctly, allow her to travel up half-pipe structures and activate certain machines, such as Spinner devices.
||Allows Samus to travel along designated magnetic rails, so called Spider Ball tracks. With this ability Samus can climb up walls and go over dangerous obstacles on the ceiling.
||These are a more powerful version of Samus' normal Bombs. While she only gets a finite number of these and must replace them as she does with Missiles, Power Bombs have a much greater destructive ability and the ability to destroy Bendezium. They are basically a nuke and like a nuke are one hit kills.
