I know there are: RID Super Sideburn Energon Rodimus Cybertron Excellion Is that it? I am not sure if there's more and would like to know. I am specifically interested in other characters or new representations that sports the look.
If you're lookin for strictly homages only (ie. characters that were not Hot Rods to begin with), include Armada Powerlinx Hotshot.
There's a lot. That's Alternator/SDCC Rodimus and KissPlay Rodimus in that last picture if you can't tell (with Mirage in the middle). Cybertron Clocker has very Rodimus tale pipe guns. Energon Checkpoint is a repaint of Energon Rodimus. Movie 1 Salvage can be made into Movie Rodimus with a Reprolabel kit. Take a look at collection threads for "Hot Rod's Extended Family Reuinion" by Odoruin (sp?, sorry I forget his full screename)) or ask the Protoman (he's the world biggest Rodimus fan/collector.)
