This hybrid was accidentally released by Raynor's Raiders when they destroyed the facility's fusion reactor. Upon awakening, it went on a rampage throughout the facility, killing terrans (of both factions), zerg and protoss alike. Unable to destroy the hybrid, Jim Raynor and his men had no choice but to run for their lives. Hoping to delay the hybrid, Raynor activated a warbot and sent it against the monster. However, the hybrid quickly destroyed the warbot. The Raiders managed to escape in a Dominion Hercules dropship, prompting the hybrid to "scream" as they flew off.
During its rampage, it only uses Consume DNA on the protoss and zerg it encounters.
