Falcona first appeared in Incredible Hulk Annual #1 (October 1968), and was created by Gary Friedrich and Marie Severin. She is one of several Inhuman criminals that Black Bolt finds guilty of treason and is banished from the Hidden Land of the Inhumans to another dimension. When the Hulk attacks Lockjaw, he teleports the Hulk to the dimension where the evil Inhumans have been banished. Falcona acquired her affinity for wild birds from undergoing Terrigenation as an infant. She can mentally control all birds of prey, especially falcons.
