In
Metroid: Other M, Samus heads to the
Bottle Ship when she receives its distress signal after laying Mother Brain to waste. The
Pyrosphere is the name of the fiery, lava-infested
third sector of the ship. In the
Geothermal Power Plant, a room located in the Pyrosphere, Samus encounters a
clone of her lifelong nemesis,
Ridley.
And here, Ridley clone shows up to fight! If you attack him enough, he'll join your side in battle. He'll also buff up his own strength if he absorbs enough energy from the vats on either side of the arena. If you manage to KO him, you'll receive an extra point to your match results, even if he's your ally at the time being. You can also interact with the FG II-Grahams, Joulions, and Zeros that appear during the fight.
