Morph

Morph, alias Kevin Sydney, is the shapeshifting funnyman of the reality-hopping task force, the Exiles. Smart, clever, and with a Hulk-sized heart, this lovable mutant dutifully protects his friends and anyone in need of his help or just in need of a good laugh. He was portrayed by Froggy in Traitor Game XI and Deadpooligan in Traitor Game XXIII.

Traitor Game XXIII
Main article: Proteus Later on his journeys with the Exiles, Morph would be taken over by the psionic mutant serial killer Proteus. As his teammates were unable to remove Proteus from his body, and with the true Morph supposedly dead as a result, the Exiles managed to brainwash the killer into only being able to access Morph's memories. During a fight with a version of the Hellfire Club, Proteus/Morph was attacked by Emma Frost before being abducted by the CSA.

Proteus spent some time in the Traitor Game as "Morph", but the brainwashing faded as he was attacked by Satan Girl. He emerged with full control of his personality once again.
