The Daily Prime is looking at another Prime that never was with these images of the Toys Alliance Mega Action SeriesTeppeki Gokin Fall of Cybertron Optimus Prime. The officially licensed non-transforming figure was originally proposed to be released along side the HUGE MAS-01 Optimus Prime.
Toys Alliance had gone as far as to tease the release, and show the prototype in 2016. Sadly, what was going to be a Masterpiece scale series, "perfect for the shelves of your collection", was never released. Check out official gray prototype design images of the figure followed by shots of the figure on display at 2016 Taipei Toy Festival.
