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.

Giant Spore
The giant spore will swing back and forth trying to hit you while the plants at the top of the screen shoot spores at you. The simplest way to defeat it is to equip missiles or Super missiles, then go into a morph ball. He can't hit you in the morph ball form, so just focus on dodging the spores. Eventually, he will stop at one side of the screen and open his mouth. Take this chance to shoot a missile into the mouth. Around six missiles should take him down.

Crocomire
Crocomire is the Norfair miniboss, available to fight once you've acquired the Super Missiles. When you drop down into his lair and move to the far right, Crocomire will jump out of the lava and slowly approach you. If you don't act fast, he'll end up pushing you all the way to the end of the room where you'll be impaled on the spikes on the wall. Its only weakness is to shoot it in the mouth. If you can hit it with more powerful weapons (Super Missiles) you'll knock it back slightly. Use them to hold him back while you pummel him with everything you have. If you run out of missiles you'll have to rely on charged shots.

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