Saint Op Omen
Savagely beating his super-ego with his id...
If you look back at how Ed hints things they fit the Reptile guess more then Nightwolf...also not many people get them right ever because he tends to go off the rails a bit...lolThe moon could be Nightwolf, but also Reptile. Remember you needed to look at the moon to fight Reptile in the original MK.
It could also be a total Red Herring or some new and completely unseen character that is somehow connected to the Moon and thus we could never guess it.
