Stilts is a member of the Decepticon offshoot known as the Ronin. He and the other Ronin are bounty hunters, tracking targets for cash, and they're not particularly picky about who. In his robot mode, Stilts resembles the Earth avian known as the crane, and his wings are able to block signal transmissions. His alternate mode is a Cybertronian jet plane.
Stilts was a member of the Ronin during the ill-fated mission at Athena, during which their ship was destroyed. He and his teammates were arrested by the Autobots and imprisoned on board the Alchemor, later escaping when the ship crashed on Earth. Following Forager's capture by Bumblebee's team, Foxtrot and Stilts succeeded in taking over the Autobots' scrapyard base by utilizing holographic disguises and manage to thaw their teammate. While the trio were plotting to sell Team Bee and the other Decepticon prisoners, Drift tricked them into thinking he was on their side again, he having previously been a member of the Ronin known as Deadlock. After he showed them a nearby Energon stash, they were taken in, and he was able to free the rest of the Autobots. Stilts and the other Ronin were soon captured and placTeam Bumblebeeed in stasis.
