Gilbert

Rotten Roger, Gilbert the Impaler, Sarah Storm are a trio of Zoid pilots, considered to be three of the best of the league. They piloted a customised Genosaurer, Red Horn and Raynos respectively. The three of them were entered into a battle royale, along with RD and Rastani. Even though the battle was a free-for-all, the four of them teamed up on RD. In they end they were defeated, thanks largely due to Roger deciding to take on the Fuzor all on his own. Though no lines were spoken, all three were present at the final battle against the Seismosaurus. Their names are simply Roger, Gilbert, and Sarah in the Japanese version of the show.
