It's a shame Takara didn't include the regular guns with the Targetmaster releases, because Topspin is one of the few figures where the entire look of the alt mode is completed by the guns. Luckily, I still had the ones that came with my Hasbro version. I also swapped over the black kneepad vents, because I like them more.
Either way this alt mode is perfection. I can't pick it up without swooshing it around, and the theme from the first stage of Axelay always pops into my head.
