The Energon Pub

You know that they make a lot of ultra magnus's.The only thing I don't like is that they take a optimas mold and paint it blue and white then call it "Ultra Magnus" .They didn't do it in RID that I know.I hope if they make any more ULTRA MAGNUS'S they shouln't copy optimas's and paint it blue and white

its somewhat of a recent trend with ultra magnus. With the obvious exception of G1, which was indeed a white Optimus Prime cab with the armor.

For the more recent lines they have each gotten there own Ultra Magnus mould.

R.I.D. Car Carrier Ultra Magnus
Armada: Overload, was slated to be Ultra Magnus.
Energon: Overload Mold in Ultra Magnus colors and actually called Ultra MAgnus.

Cybertron: I read somewhere that Metroplex was supposed to be Ultra Magnus. In Japan the name Megalo Convoy Aludes to this.

But i supposed they did this to save costs in producing an additional mould for him. Recolouring is so much cheaper.
