N'astirh is a fictional character created by Marvel Comics as a demonic inhabitant of Limbo. He first appeared in X-Factor #32 and was created by Louise Simonson and Jon Bogdanove.

N'Astirh was a demon with great magical skills and a master manipulator. Despite his power and loyalty to his lord Belasco N'astirh rebelled when Belasco chose a human, Illyana Rasputin as his apprentice. N'Astirh formed an alliance with S'ym, the strongest of Belasco's demons. When Illyana rose against Belasco, N'Astirh stole Belasco's spellbook and fled from Limbo into Earth's past. When Illyana left Limbo, S'ym summoned N'Astirh again and they plotted against her. Due to the Magus invasion of Limbo (or "Otherplace"), S'ym was turned into a techno-organic being. As a techno-organic being, S'ym became more powerful and took over Limbo.

N'Astirh made pacts with various villains in the Marvel Universe, and his first alliance was with Cameron Hodge. N'astirh's demons then kidnapped Artie Maddicks and Leech. Using Belasco's stolen book of spells, N'astirh sent demons to abduct mutant infants, and was brought computer expert Wiz Kid as a captive. N'astirh was informed by Cameron Hodge about Mister Sinister's orphanage for mutant children. N'astirh forced Wiz Kid to create a computer to process magic. N'astirh then transformed Hobgoblin (Macendale), giving him demonic features and powers. When Jason Phillip Macendale, then the Hobgoblin, offered to make a Faustian bargain to trade his soul for the power of a demon, N'astirh laughed and scoffed at the offer, thinking Macendale's soul to be too pitiful to be of any worth. In return for amusing him, however, N'astirh granted Macendale's request by fusing the hapless human with a demon, which would eventually break away to become the Demogoblin. Archangel vowed vengeance on N'astirh. N'astirh also made a pact with Madelyne Pryor, who used this alliance to get revenge against her creator Mister Sinister and her ex-husband Cyclops.

N'astirh brought Madelyne Pryor to Mister Sinister's genetic lab at the orphanage, to rescue her baby, and to confront Mr. Sinister. Madelyne learned that she was merely a clone of Jean Grey, whom her husband had actually loved, and he left her upon learning that Jean was still alive. With the help of N'astirh and his fellow demon S'ym, Madelyne's psionic powers (far stronger than her progenitor's) were triggered, transforming her into the Goblin Queen. When N'astirh realized that Madelyne could not be used as his pawn openly he devised another way of coercing her to the dark side. When she was bound and defeated by Sinister he left her to fend for herself while he battled S'ym, and was infected and transformed by the transmode virus. The virus changes his coloring from green to red. He also claims he has 'become' magic, since he can now process and cast spells almost simultaneously.

N'astirh has not been a contender in any CBUB matches.
