Parasite (Zebes)

Bomb Parasites, also called Bugs, Blootiks, and Bomb Bugs, are small creatures native to Zebes. In Metroid: Zero Mission, they attach themselves to Samus Aran, causing damage with large numbers until she obtains the Varia Suit. They are the only creatures that can destroy Zebes Bio-Barriers. Bomb Parasites can be destroyed by Bombs.
