Super Metroid/Bosses

''For typical enemies see Super Metroid/Enemies. Bosses are listed in order of appearance.''

Mini Bosses
Mini Bosses, like Bosses, serve to hinder Samus' quest in exploration of Zebes; most often with a power-up nearby (before or after the fight). The main difference between Mini Bosses and Bosses is the difficulty, size and effect on the game.

Ridley (Space Station Ceres)
Ridley will pulverize you in this fight, he's invincible so don't even waste time fighting, try to get your health under 30 to win the fight.

Bosses
The four bosses, Kraid, Phantoon, Ridley, and Botwoon must be defeated before the way to Mother Brain is opened (Tourian).
