In this event, the player controls Samus in a special single-player stage not found anywhere else in the game, Tourian. To clear this event, the player must defeat Mother Brain, who has 200 health points. Like her Assist Trophy form, she summons a swarm of Rinkas that damage opponents on contact. She can shoot her powerful Laser Brain Attack several times that deals heavy damage on the player. The theme Vs. Ridley plays during the fight. The ranking the player gets is based on how much time it takes him/her to defeat Mother Brain.
