Description
This is a recreation of the Mother Brain battle from Metroid, and involves Samus firing Missiles at Mother Brain. The only thing keeping Samus from defeating Mother Brain are the occasional shots from the security sensors. Interestingly, she cannot move, but her Morph Ball is still functional.

The battle is mostly the same as it was before, but Samus now has eight Energy Tanks, and when the Mother Brain's glass chamber is broken, more of it opens up. Rinkas are also not present. As well, the sound effects are slightly different, with the Missile shots sounding more like when the Kiru Giru from Metroid: Zero Mission is pushed back.
