Underwater flames

From Glitches

From the game Metroid Prime for the Nintendo Gamecube

Use sequence breaking to obtain the Plasma Beam as early as possible. Take it to the crashed Space Pirate Frigate your first time through, and use it on the underwater enemies (especially the Aqua Pirates.) They should catch on fire, while underwater! They take damage like normal, and they even disintegrate like they normally would as if you charged up first.
