lol it's so clear that the original one is the one of the left, and the other ones are poorly shopped modifications >_>. If midway've done this... I'm dissapointed.
Of course it's copy/paste, just a brief modification on weaponry, shape of the hair, REALLY POOR color filters (such as the skin in the middle) and that's it, because no-one will notice that the purple suit has no shadows at all, nor the green one... Lazy ppl are lazy.
