In one of my very first appearances, I attempted to escape from Thor by summoning a flock of pigeons.
I have also attempted to evade Thor by turning myself into a pigeon. This attempt... did not go well.
In another early appearance, I enacted an impenetrable barrier around Thor's hammer. In his Donald Blake disguise, he tricked me into dropping my guard with a cardboard cutout◊ of Thor.
I gave the mercenary Deadpool his gift of Breaking the Fourth Wall by doing it myself. I also convinced him he was my son, to get back at Thor. When Deadpool failed to defeat my brother, I cursed Deadpool with the face of Tom Cruise and made him completely indestructible until he apologized.
