>>6733660You'd be better off asking if Mewtwo can stand without the stand. And the answer is no.
(Some people will say yes, but those people are either letting his rest on the back of his digitigrade heels or leaned back on the tail.)
The tail and all its joints add a lot of weight to the figure, while he's supposed to stand upright on tiny, rounded feet with two sets of joints down there. Not gonna happen.
