For example, Energon Energon Strongarm (not a typo) was released in Japan as simply "Strongarm", while the standard one was called "Blastarm". Since I use the Hasbro names mostly, I call the blue one "Blastarm" as a different character. Often Japan will have multiple versions of characters and using the Japanese name for the "extra" can give a whole new character. Others include: Superlink Ariel Paradron type: Paradron (Pink one is Arcee) Superlink Shadowhawk Cosmo type: Blackout (based on a mistake in the show. White one is Divebomb) Superlink Chromehorn Forest type: Chromehorn (Green & Yellow one is Insecticon) Galaxy Force Rumble: red Rumble, blue Frenzy, yellow Scrapmetal. The US calls Scrapmetal a Terrorcon, so like the others, these three represent the Generals of the Scrapmetal army. Armada Powerlinx Cyclonus: Springer (Aaron Archer said he intended to call him that but was too late. Yup, a Decepticon named Springer). Armada Powerlinx Thrust: Dirge (once again, another that Aaron Archer said was intended to be used, as the red one was supposed to be Powerlinx Thrust) Energon Energon Ironhide: Hound (when we first found out about it, TRU's system said "Energon Hound".. So I figured "why not?" Probably another that was intended as a new character.. After all, almost all of the Energon Voyagers repaints were new characters, toy wise in the US, right?) G1 Yellow Cliffjumper: Blow-Out (the original Budiansky name for Cliffjumper. Why let a name go to waste? Same mold, too) G1 Red Bumblebee: Ladybug (no real reason. It seems appropriate) Diaclone Red Sunstreaker: Spin-Out (originally, Sideswipe and Sunstreaker's colors were reversed and the yellow Sideswipe mold was to be called Spin-Out. However, that particular figure got a new official name in Tigertrack. So I recycled the name for the red Sunstreaker) Those are the ones I can think of at the moment... All but Ladybug have a legit rationale, too.
