Treacheron is new to the villainous cast, so I know little about him.  I do know that he took Furio's place as Scorpius' head minion when Furio blew himself up.  He has a unique outfit; he kinda looks like a stingray, don't you think?  That black ponytail he has makes him look good, too.  Also, the voice attracted me.  His battle grunts sound kind of like Elgar's.  I can't say much more.
