Depending if the secret endings are used, then it might be something that can be redeemed. I mean, I saw his teleport ability as a subsitute for the Teleportation belt. Thou am hoping he lost the swords in arms.
Or maybe they will go with the ending which stated that "the dead pool" was a clone of Wade... But then it will be Deadpool with a sword and a mouth. He wont do the insane stupid things he usually does.
