Help finding body

Hmmm... I'm not overly familiar with him but going off what I can tell from a google search I would look at Naruto for the upper torso (it's a bit bulky on the torso, but the zipper, jacket bottom, and arms are pretty similar and you can thin out the sides and back pretty well) though I'd look for another figure for the legs (rock lee if you want to keep to the same line, but plain pants are pretty basic)

There are some other figures that could also work, such as Master Asia from G Gundam (I've seen a decent tracksuit Gohan done with it) there's a tracksuit Bruce Lee, and if they make a DBS 17 the upper torso might work ok... but I didn't like the bulk of most of them. I'd also look into school anime figures, since I feel the arms and pants would match ok from a typical male school uniform.

Thank you! I think naruto would work very well. I have not seen naruto so I did not think to look for them. Master asia also might work. All your sugestions are very helpfull, thank you.
