My thoughts exactly, maybe his magic makes him look like we see him normally and when he got drained he was unable to keep the facade without risking himself.
Maybe original recipe Warlock is in the other cocoon?
That would be a sight!Big T coming back from Death to show Vulcan who is the universe!!!Anyway it wouldn't be an easy task, Vulcan wasn't going all out with Warlock, considering all he has accomplished since he showed up, I wonder what would it take to kill him.
I didn't know where to put this one but it was too good to pass. After the enchantment he used to seal the Fault, Warlock altered his own past becoming the Magus, then he massacres the Guardians until he is stopped by the Cosmic Cube:
