Marvel: Possession Resistance

Wade Wilson (Deadpool)
Similar to the telepathic immunity, Deadpool is able to remain in partial control of himself while supernatural beings are trying to take control of him. During Xaphan's attempt to take control of him, Deadpool was able to fight for control of his body. Because half of his soul is owned by Satana by rules of marriage, no one can touch his soul. Deadpool even remembers Spider-Man unmasking as Peter Parker during the Civil War, even though Mephisto erased that event.
