Hot Stuff the Little Devil is a comic book character created by Warren Kremer who first appeared in Hot Stuff #1 (October 1957), published by Harvey Comics. 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. Much to the consternation of his demonic brethren, Hot Stuff sometimes performs good deeds to irritate them.
