Hybrid unleashed

It was accidentally released by Raynor's Raiders when they destroyed the facility's power core, and went on a rampage throughout the facility, killing terrans (of both factions), zerg and protoss alike. The Raiders escaped in a Hercules dropship, prompting it to "scream" as they did so.[1]

Its scream was so powerful that it was felt by telepaths aboard Hyperion.[2]
