Go big or go home. Isn't that the saying?
Well apparently it applies in cosplay too. Because this particular cosplay features one of the X-Men's longest running and largest villains, Apocalypse. And the cosplay requires essentially a full bodysuit as you can see.
This version of Apocalypse looks to be from earlier in the X-Men's run, actually back when he was introduced in X-Factor. In those days he had the habit of randomly changing sizes and sprouting mechanical implements at the end of his arms.
