Power-ups are items that Samus Aran uses in every Metroid game to gain new abilities and powers. In the Metroid Universe, there are many different kinds of Power-ups. There are Power-ups for beams, suits, Morph Ball modes and jumping abilities. Power-ups will usually give Samus an ability that she needs to reach and explore a new area. Also, not all Power-ups are needed to clear the game. Items such as the Spring Ball in Super Metroid are Power-ups that make exploration easier, but are not required.
Power-ups in most Metroid games are pieces of Chozo technology used to expand the Power Suit. In Metroid Prime 2: Echoes, there are also Luminoth Power-ups. In Metroid Prime Hunters, there are beam Power-ups of Alimbic origin. Finally, there are also Power-ups that the Galactic Federation has been able to design for Samus' use. The best examples of these are the downloadable Power-ups acquired in Data Rooms throughout Metroid Fusion.
Throughout the Metroid series, Power-ups have taken on many different appearances. In most of the games, the Power-up's appearance is a symbol for what it does; for example, the Morph Ball Bomb Power-up is a case with a bomb in it. It is note-worthy that the Screw Attack Power-up (usually a red or purplish-black ball with a small yellow lightning strike on it) is used as the Metroid series' main symbol. Many Power-ups can be found in the hands of a Chozo Statue; if this is the case, then the Power-up will often be concealed in a protective casing commonly referred to as an Item Sphere. To break the sphere, all Samus has to do is shoot it with a beam; any beam will do. Some Power-ups will float in mid-air until Samus touches it (this is common if the Power-up is gained from a boss), some are placed on various pedestals in rooms, and some of them are just hidden in various places and sit on nothing in particular. In Metroid: Other M, all power-ups except the Diffusion Beam, Seeker Missiles, Missile Expansions, Energy Tanks, E-Recovery Tanks and Accel Charges are obtained through data and do not have material form. In Metroid Fusion, some power-ups are received as data and do not have a physical form. Metroid Fusion also has power-ups in the form of an enemy, the X, which must be absorbed to receive some power-ups. To help Samus find the better-hidden items in the Metroid Prime games, all Power-ups will give off a faint humming noise to advertise their presence.
Metroid Prime manualEdit
"As Samus delves deeper into the Space Pirates' operation, she'll find power-ups that improve both her arsenal and her suit. Every power-up she finds will help her access something new in vast regions of Tallon IV, so remember areas where she can't progress and return once she's gained new abilities. Pay special attention to the colors of closed doors, as they should help you determine what weapons you need to use to open them."
