Type:Null - Since it's not known how this thing evolves it's hard to say, I would like to think that the evolution will be one of two things, a more cursed form that has adapted the frankenstieness of its base form into a more cohesive design, so perhaps both legs have a combination of the hexagonal shapes and the talons etc. The other route I see it taking is the "path to purity" basically it becomes a more pure Pokemon, uncorrupted by human intervention and while not completely devoid of its messy appearance it does look more like its true form or something.
