Crystallized Fuel Gel appears on Bryyo in Metroid Prime 3: Corruption as a minor obstacle. They originate as Fuel Gel and then form into a cluster of crystals. They are vulnerable to weapon fire, and when destroyed they will trigger something. Their most notable appearances are in Overgrown Ruins, Burrow and Ruined Shrine. The ceremonial armor of the Reptilicus may be forged from Crystallized Fuel Gel, due to the color and the crystals' resilience.
