Hydra (AUS)

A horrifically mutated Reaver, the Hydra is a unique species within the Locust Horde. Although only one is known to exsist, the Hydra is the personal mount of the High Kantus Priest, Skorge. The Hydra is an incredibly loyal companion of it's master, and has served him for many years. Although the nature of it's transformation is unknown, it is still nontheless a beneficial upgrade to the average Reaver.

In Zombies
The Hydra only appears during the Kryllstorm major easter egg, in which the player commanding Skorge has to take to the skies along with General RAAM upon his personal Reaver to prevent the Lambent from killing or wounding the Seeders. After the step is complete, an Infinite Dragon shoots the Hydra and RAAM's Reaver down, with Skorge and RAAM just barely surviving. What became of the Hydra is unknown.
