King Kihunter

Unidentified Life Form 58 is a large Keyhunter-like insectoid encountered by Samus in the Biosphere's Biological Experiment Floor on board the Bottle Ship. It lives inside of a massive, purple hive suspended in the room's lower level, and constantly summons more Keyhunters to defend itself until Samus kills it and destroys the hive. It appears to be some form of Keyhunter queen, and when Samus kills it both its body and the inside surface of the hive begin to shrivel and turn grey, suggesting that the hive is in fact an extension of ULF 58's body.
