Warbringer

The Warbringer was a powerful Protoss Reaver. Compared to a regular Reaver, it was much tougher, and all Reaver upgrades were default on Warbringer.

The Warbringer was captured by Schezar's Scavengers and placed in a Stasis Cell on Aiur. Protoss Praetor Mojo enlisted the help of a breakaway faction of Alpha Squadron, a Terran military unit within the Terran Dominion, led by Tom Kazansky and Magellan. The Terrans rescued Mojo, the Danimoth and the Warbringer from captivity.

The Warbringer took part in a mission to destroy a Cerebrate captured by the Scavengers, alongside Mojo's Boys and the breakaway Terran faction. The mission was a success.

Trivia
In the final mission of StarCraft: Enslavers, all heroes (including the Warbringer) are expendable.
