Should I get a Tekken Gashapon?

Today I was going through some shops when I came across Tekken Gashapon. Being a big Tekken fan I would have done anything to have it, there is however one problem. The figures look really......awkward? (and fake). I checked the side of the box and even the preview picture looked weird. Are these things even real? Were these just made by a fan? Or are they legit?
