S'ym is the most physically potent native demon of the demonic realm called Limbo, also known as "Otherplace."

Along with N'astirh, S'ym is one of the better known demons of Limbo. He used to serve under Belasco, an ancient evil sorcerer serving the Elder Gods. Belasco was seemingly killed by Ka-Zar, after which S'ym became Limbo's de facto ruler.[citation needed]

S'ym and N'astirh took in Madelyne Pryor. She was a clone of Jean Grey, and the demons were going to use her in a demonic invasion of Earth starting with Manhattan.[citation needed]

At one point, S'ym posed as the green two-headed Duke Bleys.[citation needed]

S'ym was seen when Illyana Rasputina, formerly known as Magik, returned to rule Limbo in her Darkchylde persona. S'ym, who used to be infected with the Transmode virus, is shown to be one of her servants now free of the techno-organic virus.[citation needed]

S'ym decided to take a chance of ruling Limbo himself after Madelyne Pryor returned to Earth. A new Soulsword was held captive at a place called the Screaming Tower. Belasco enrolled the aid of Mary Jane Watson and the Black Cat to retrieve the sword so he could return as Limbo's ruler.

S'ym encounted and rescued Mary Jane and Black Cat at the tower and the three decided a truce to find the sword. S'ym was immediately honest to both Earth girls about betraying them when they find the sword, which they appreciated. During the search and a battle with the Soulsword's guardian, S'ym was killed.

Mary Jane used her new, mysterious jackpot powers to restore S'ym back to life. In return, S'ym revealed that the Soulsword would be bound to whomever found it, something Belasco never told the two Earth girls. The three find the sword and make their way back to Belasco, where they trick and overthrow him. S'ym is revealed to be the new owner of the Soulsword and Limbo's new ruler. He enslaves Belasco as his minion and as a thank you sends Mary Jane and Black Cat back home to Earth.

  • Superhuman Strength: S'ym possesses great superhuman strength and can lift over 90 tons.[2] He is stronger than Colossus and easily snapped off one of Wolverine's claws.[3]
  • Superhuman Durability: S'ym is nearly invulnerable and can resist magma and even adamantium blades.[2] Illyana Rasputin's Soulsword was one of the few weapons that could kill him, before having been infected by the techno-organic virus. During the Inferno storyline Illyana tried killing S'ym with her Soulsword but it proved ineffective against his new circuitry body.[citation needed]
  • Regenerative Healing Factor: S'ym, now a techno-organic being himself, can repair himself and reform from a single molecule, should he be destroyed.[2]
  • Infection: Also due to his techno-organic state, S'ym can also infect other objects and feed off its life energies, and/or turn them into techno-organic beings as well.[2]
  • Shapeshifting: The techno-organic virus allows S'ym to change his appearance, grow in size and mimic the function of any machine.[2]
  • Energy Absorption: S'ym can drain the energy of other techno-organic beings as long as their will is weaker than his.[2]


  • S'ym's name and appearance are a reference to Dave Sim's creator-owned character Cerebus the Aardvark. (Sim had previously introduced a character parodying S'ym's creator Chris Claremont in Cerebus #23.) Like Cerebus, S'ym refers to himself in the third person while speaking.
