User Carnivius_Prime on Seibertron has posted what looks as though an Argos (UK) Exclusive Voyager Class Optimus Prime.
The figure in question is a repaint of Transformers: Dark Of The Moon Voyager Class Optimus Prime with a red Shield and a red Sword to match its red colored tires.
However, we emphasize on the fact that Argos tend to make mistakes on their listings and may even accidentally feature knock-offs. Even on the same listing, Voyager Class Megatron is listed as a Legion. Therefore, take this info with a grain of salt.
Then again, we should not forget the TRU Exclusive Mission To Cybertron Bomber Megatron who is a repaint of an older figure as well.
Only time will solve this mystery. Meanwhile, check out the image after the jump.
