Well...here's Tomy's effort at Metal Sonic.
This is probably technically a 'Boom' item, but really he's pretty similar, and it's not like the craftsmanship here is much good. It has super long monkey arms, sad bent nose, & tiny odd round feet. Worst of all though are the hands/fingers, first off there aren't enough of them...somehow? Why only 4 fingers? Then, they're so fat and blunt and just odd/cheap looking. It's not like the doll is tiny nor is it inexpensive, it's at least 12.00 for this sad item. It's not quite a 'mutant gear' thing, but really, it's borderline. It's sad to see Tomy with the license, and not even trying to make something good.
