Sister Psyche is a fictional character who appears in the City of Heroes universe of games, novels, and comics. She is one of the more powerful psychics in Paragon City.
After the onslaught of the Rikti War, Shalice Tilman's body was damaged to the extent that Sister Psyche was forced to put her mind into the body of another superheroine, Aurora Borealis. Eventually, Numina attempted to return Sister Psyche's mind to her original body, but this left Aurora Borealis weak, and her husband sought out the assistance of other heroes to help. When the ritual was complete, Sister Psyche returned to her original body.
When Arachnos attacked Paragon City in City of Heroes #1, Sister Psyche's mind was split, again, between herself, and the mind of her former host. Upon being exposed to the Flame of Prometheus, her mind was eventually restored to its original state as well as her powers.
Later on in the series, Sister Psyche is abducted by Arachnos' agents to power a new giant spider-like robot. However, Lord Recluse's plans failed when it was revealed Manticore was a double agent, successfully saving her from a grim fate; unlike the other members of the Freedom Phalanx, Shalice was in on Manticore's plans. This arc in the series lays hints at a relationship between between Sister Psyche and Manticore, though she initially states that what Manticore feels for her can't be accurately described as love. Oddly, the final arc of the series culminates in Sister Psyche's acceptance of Manticore's marriage proposal.
On February 14th, 2008 in an in game event on the Traing Room Server, Manticore and Sister Psyche tied the knot, though immediately after the ceremony they were attacked by Lord Recluse and his minions but successfully fended off the attack.
