Reptile kicks ass no matter how he looks. However, his MK:DA outfit sucked. I like the fact that they were wanting to show the more "reptile" side of him, but he does not look like an iguana. Reptile is a raptor, meaning he looks like his mk2 ending pic without his mask. The best thing they need to do for him in the next mk game, is make him have his mk2 outfit on and his alternate can be a more reptilian look. I think that would be fair.

i think he will have a costume of himself in "human" form in MK7 if he ends up in MK7.

as for his looks in past MK's.... i HATE his MK4 look. atleast his primary one. i LOVE his MKDA look. but i want him back to looking human as well. and i really think theres a good chance he will cuz in Sindel's ending in MKD (wich i think is false but still...) u see Reptile go back to his human looking form after Sindel kills Onaga. i think that is what will happen and taht the evolution process of Reptile will start again.
