Metroid Fusion 2: Renegade

Playable characters
One note represents the main suit and the following replacements, while two notes are upgrades to said suit

Samus Aran
Samus has the unique ability (Thanks to the SA-X mutation) to absorb suit upgrades and switch between them on the fly. Similar to the Souls in Metroid: Dread, The suits have their own upgrades that can only be used by them, and do not stack with other abilities to Samus' main arsenal (Mainly due to her retaining her abilities from the previous game, albeit nerfed).
