[1] He has granted power to his cult, the Sons of Satannish, and struck a pact with the human sorcerer Lord Nekron, first encountering Doctor Strange during this affair.

He battled Mephisto in New York City and briefly fused with him as a result of Doctor Strange's spell, revealing that they were formed from the same demonic energy.

[5][6] During the Secret Invasion storyline, Satannish is imprisoned within Avalon before escaping when Pete Wisdom releases Merlin.

Satannish is more akin to a supernatural force of nature than a being; as such he possesses "virtually unlimited" mystic power which can be used for a variety of effects,[14] including (but not limited to) inter-dimensional teleportation, manipulation of time, space, and matter, size transformations, casting bolts of mystic energy as destructive force, demonic possession, and physical strength and durability.

[8] Satannish makes a non-speaking cameo appearance in Morrigan Aensland's ending in Marvel vs. Capcom 3: Fate of Two Worlds.
