Some people have said that the Generations Voyager Optimus has a bit of an Energon Optimus look to it, particularly as a combiner... so it probably isn't surprising to hear that Ehobby in Japan have announced an exclusive redeco of the mould as Grand Scourge, which homages the Japanese redeco of the Superlink (Energon) Optimus way back in 2004. (which was actually a redeco of the Superlink Optimus model kit)
It is priced at 6,500yen (about AU$70) for release in September (May 26th is the pre-order date)... with a bonus sword, from the Beast Hunters Ultimate Optimus toy.
No mention of any redeco Deluxes to go with this figure, so it gives us another Voyager combiner without limbs.
(we need more Deluxe redecos to make up the difference)
