There is one sure fire way to tell it's a bootleg. Check the Hasbro emblem at the bottom of the package. The dumbass that made the packaging screwed it up by spelling it as "Hrsbro".
And I have been collecting international figures for over a decade. This figure is not common and a authentic one is hard to find. So if the seller has sold 21 of them, and has more to sell, then all signs point to a fake.
This is a fake.
