Takara-Tomy featured two custom Revoltech figures in their booth at Wonderfest: Ultra Magnus (linked above) and Shockwave, both of which I would purchase in an instant if they were actual retail products. This is extremely similar, if not the same one as, the Shockwave custom Revoltech figure that showed up at Botcon last year.
