Transformers: Energon
Wheeljack is the Japanese name of the Autobot Downshift, who greatly resembles the Generation One Wheeljack. It is generally assumed that Energon (Transformers: Superlink in Japan)'s Wheeljack/Downshift is neither the same character as the Autobot deserter Wheeljack, nor the Mini-Con Downshift from Armada.
Energon's Downshift is carried over to Transformers: Cybertron, as an early 1970s era muscle car based on either a 1970-74 Plymouth Barracuda, or 1970-71 Dodge Challenger who again turns into an homage of Wheeljack.
