its true there were VERY few spartans that had the description of "HYPER LETHAL" and John-117was one of them, Noble ix was another and there was one other...i think he served with John...n I think he is one of the few that survived to the days when they formed the Spartan 4 program. cause contrary to the whole 'oh master chief is the only survivor' thing isn't entirely true...Jun (Noble 3) is still around when they made Spartan 4's. and so is the other guy who is nearly as tough as John...Frederic, that was his name Frederic-104.
