Etrigan
Even among demons, Etrigan is considered to be extremely powerful. He has above superhuman strength (mystically enhanced) to the degree that he can stand against other powerhouses like Superman, Wonder Woman, and Lobo. He has a high degree of resistance to injury and can project hellfire from his body; usually from his mouth. He has a very high command of magic. Other powers include mystically enhanced fangs and claws, enhanced senses, super speed, agility, telepathy, energy blasts, and precognition. His sadomasochistic nature allows him to enjoy pain as if it were pleasure, making him generally fearless in the face of combat and torture. His healing factor can handle an incredible amount of damage, allowing him to recover from wounds that have removed large sections of his body.
As seen in Batman: The Brave and the Bold, it appears that he also has some matter manipulation power on a molecular level. His powers can be extended by other magical devices, such as the Crown of Horns. Etrigan is also provided with insight to religious aspects and other forbidden or secret knowledge.
