Demon, or Gene Simmons being his human name, is a powerful hero from the world of Kissteria. He has the ability to fly and can control fire with pyrokinesis. He is also able to produce flames from his mouth and has an extremely long and pointed tongue. He is the most aggressive out of the KISS band, but he does have a bit of a soft spot somewhere under his grumpy attitude.

"Hmph... Leaving me to babysit a mortal."
