Even among demons, Etrigan is considered to be extremely powerful. He has above superhuman strength (mystically enhanced) and a high degree of resistance to injury. He can project hellfire from his body; usually from his mouth, and 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. Etrigan is also provided with insight to religious aspects and other forbidden or secret knowledge.

Gargoyle can fly, and is able to fire bio-mystic blasts which steal part of the victim’s soul; he can also reverse this to strengthen others with his own life-force. He can form bio-energy shields to deflect magical attacks, as well as transmute matter. This bio-energy also jams sorcerer's attempts to locate him. His body is immortal, does not need to breathe, can regenerate lost limbs, and is super-humanly strong and durable. He can breathe a bio-mystic fire which can remove madness and evil from people. But The Gargoyle can be used as a familiar by more experienced magicians, and Isaac has a limited knowledge of magic.
And if you break down their skill-sets into (non-existent) HeroScape stats- you'll see that they're pretty evenly matched:
So, as Dale is fond of asking: Who wins and why?
