[1] Imbued with a mischievous personality and able to produce fire, Hot Stuff appears as a red child devil who wears a diaper (said to be made of asbestos) and carries a magical sentient pitchfork (referred to as his "trusty trident"), which is a character in its own right.

While Harvey Comics flagship characters Casper the Friendly Ghost, Spooky and Wendy the Good Little Witch often crossed over into each other's stories, Hot Stuff rarely appeared with them.

Instead, the little devil would be featured with characters like Stumbo the Giant (created by Warren Kremer and Larz Bourne, and appeared in back-up stories in Hot Stuff comics in 1957), Katnip the cat, Herman the mouse and good fairy Princess Charma.

He was the mascot of Joey Harrison's Surf Club in Seaside Heights, New Jersey, and was also the inspiration for the logo of the Chicago based street gang Satan Disciples.

[citation needed] Hot Stuff makes a cameo in a 2014 episode of The Simpsons titled "Treehouse of Horror XXV", in which he was put in "Super Hell" for how "lame" his comics are.
