Here's a quick list of the changes as noted by Powered Convoy:
- His leg panels won't break off if they come off.
- His back panel attaches securely (perhaps even better than the Hasbro one) in robot mode.
- No issues pegging his chest into place.
- He holds his guns extremely securely.
- His wrists are not loose and do not wobble about.
- No issues with the ankles (that I can see).
- His spoiler slides in easier when transforming to Rodimus Convoy vehicle mode (though you still may get some rubbing).
- He has the Rodimus Convoy biceps rather than the new type that came with Rodimus Prime.
- His maroon paint in robot mode is very light compared to the original.
- Orange plastic is a little lighter.
- Yellow paint is slightly lighter.
- Maroon paint on Rodimus Convoy cab portion is darker.
- Biceps have a different sheen to them (perhaps they are made out of a different kind of plastic).
