Fuel Gel

Fuel Gel is the liquid in Metroid Prime 3 Corruption used primarily as fuel for ships. It is volatile and will ignite easily. According to a creature log, it can give off toxic vapor. The Federation has control over distribution of the substance and proceeds from Bryyonian gel sales go directly to the Federation military forces protecting that sector of space. Space Pirates are said to desire the liquid so the Federation works to increase anti-piracy defenses. In some qualities, it's similar to phazon, although not as powerful in energy output. It can be frozen and can damage the shielding in Samus' powersuit if she's in direct contact with the liquid gel.
