This one is not as simple as it may seem.
I had a regular Wonder Man years ago but used it for customizing. Then the price of the figure raised and I was unable to find another one at a good price. But the ionic variant, though, is still affordable.
So I took a Warpath (Dark X-Force costume) and put the repainted ionic head on it.
I switched legs with with MI Machine Man, so he could have rocker ankles.
Found him a pair of fists, as I think it's more fitting for a brawler like him.
And here he is : Wonder Man. Nice than the regular fig and cheaper, too !
