Hybrid reaver

The hybrid reaver is an extremely powerful zerg-based type of hybrid.

History
A hybrid reaver was created in a secret Terran Dominion facility at Castanar.

Raynor's Raiders discovered the creature and destroyed its holding cell. When the cell was destroyed, the reaver then proceeded to destroy the facility. The Raiders barely escaped into a Hercules, after which the reaver "screamed" at them.

Armageddon
In a dark apocalyptic future foreseen by the Overmind and others through it, many hybrid reavers were deployed to help destroy the protoss during their last stand.

Game Unit
The hybrid reaver is seen in In Utter Darkness and a particularly powerful one is seen in Piercing the Shroud. Unlike the hybrid destroyer, reavers focus on physical attacks.

Development
Originally the protoss-based hybrid destroyer was the only type of hybrid unit in StarCraft II. The idea of a zerg-based hybrid had been pitched by Samwise Didier in concept art, (labelled as a "high breed") but was effectively abandoned for a year. Eventually the idea of a zerg-based hybrid was pitched within the design team and Didier's concept was resurrected as the hybrid viper. In the final game it was known as the hybrid reaver&mdash;mostly the same, but unlike the viper, it had tentacles coming off its back.
