He also sports a pocket watch with chain, and a chained silver lapel pin bearing the Funtomdrum crest,traditionally worn by the house's head butler. White gloves conceal the mark of his Faustian tattoo which was given to him while enslaved, that is on his left hand.Occasionally, he removes his white gloves, revealing black fingernails.

Major BattlesEdit


When you were standing in the wake of devastation when you were waiting on the edge of the unknown with the cataclysm raining down, insides crying save me now you were there and possibly alone. Do you feel cold and lost in desperation you build up all the failiures all you've known remember all the sadness and frustration and let it go, let it go. Other wise if you have all that and don't it will come back to haunt you. Remeber that and live by it.


  • A running gag is Catalyst pulling out simple silverware from his coat and using it to completely beat an enemy into submission.
  • Another running gag is for Catalyst to ignores order when around cats.
  • He keeps many cats hidden in his closet, to make sure so others don't find out.
