The Ultimate Fire Demon is a one-time character who appears in "Forces of Nature". This demon was created when Thunder and Lightning were tricked by an old sage into creating a fire large enough so that the sage could manifest it's power to become a large pyrokinetic demon.

The demon slowly marched to Jump City, with all of the Titans (except Robin) attempting to stop it.

It's death came at the hands of Thunder and Lightning, who created rain to decimate the demon, after the failure of the Titans.



  • This demon appears to be a gigantic version of one of Trigon's fire demon servants.
  • Although the power of the Titans could not stop it, interestingly, a rather simple part of normal nature (rain) could.
  • The Ultimate Fire Demon is the first character to die in the series.
