[@Kazemitsu] Oh, please don't be a character who might accidentally consume something the X were copying.  That would actually be like Blair from The Thing, where suddenly you realize your biology may be compromised and quietly changing until you're no longer you anymore, because you've been consumed.  And I know there'd be a question of this species being geared to take that on from the point of digestion, but I feel like the X would glob out and hopelessly infect him as soon as it enters the mouth.

So, tell me about this dragon, then.
