Metroid Prime

Phaazoids are masses of Phazon energy that form after a Leviathan has been destroyed. They still retain a small bit of sentience and are mindlessly aggressive. The only way to damage a Phaazoid is by attacking it with Phazon- based attacks. However, this has a side effect of causing the creature to split into two smaller forms. Once the Phaazoid has split small enough, it will simply fly at a target and detonate on contact. It is said that some Phaazoids may split into a rare, crimson-colored form.
