A Power Bomb Expansion, also known as a Power Bomb Tank, is an upgrade that allows Samus Aran to carry more Power Bombs in her suit. They are usually found at the end of secret passages, just like Missile Tanks, that sometimes can only be accessed in Morph Ball Mode. They are featured in every game except Metroid, Metroid II: Return of Samus, Metroid Prime Hunters, Metroid Prime Pinball, Metroid: Other M and Metroid Prime 3: Corruption. Power Bombs can destroy Bendezium, Denzium and destroy or do serious damage to some creatures. In Super Metroid, a single expansion increases Samus' Power Bombs by 5, in Prime series by 1 and in Metroid Fusion and in Metroid: Zero Mission by 2.
The 2D Metroid games used the term "Power Bomb Tank", however it seems to have been replaced by "Power Bomb Expansion" in the Prime Series. Samus is capable of carrying 8 in the first Metroid Prime, as she gains 4 upon acquiring the Power Bombs, and there are 4 more expansions to be found scattered across Tallon IV. In Metroid Prime 2: Echoes, Samus can carry up to 10, as she starts off with 2 and has to collect 8 more scattered throughout Aether.
