Skaarj Hybrid

The Skaarj Hybrid is a hybrid lifeform with both Skaarj and Human DNA, closer resembling their Skaarj ancestors. Two teams of hybrids, Red Claw and Iron Skull were entered into the Liandri Grand Tournament in 2341, during the time of Unreal Tournament. Level 9 security clearance is required to access information on any member. Iron Skull hybrids resemble Skaarj less, which suggests their design strayed further from the Skaarj genetic code than that of Red Claw hybrids.

Descriptions of members of UT2004's Black Fist Clan, a team of regular Skaarj augmented with cybernetic armor, mention they were injured in a fight with the Iron Skull clan.
