Retrax is a Transformer of the Beast Wars Universe. He is a member of the Predacons. His beast mode is Pillbug. He is a decent warrior because he wants to overpower his enemies. He specializes in desert demolitions and lives in tunnels under the desert, which keep him cool. His companions are the remains of his enemies. He is a coward at heart, however, and at the slightest hint of being overwhelmed will bounce to safety in his "bug ball" along one of his many pre-determined escape routes.
