|Episode(s)||15.11 The Gamblers|
Kabaiel was a grigori, among the first angels on Earth. Like the rest of his kind, Kabaiel has been feeding on human souls for centuries, though he feeds off children. He is targeted by Jack Kline who wipes out the rest of the grigori, including Sariel, who sent a message to him over angel radio.
Jack manages to locate Kabaiel, who walks around town carrying his sword in a suitcase. He follows the grigori to an abandoned building where he is subsequently captured.
In a nearby church, he plans to torture Jack and question why he's targeting his kind. However, Jack remains silent and chooses not to use his powers to escape or heal his wound. He knew that Jack allowed Sariel to call out to him to draw him out and kill him. He proceeds to torture Jack as retribution for slaughtering his kind, despite knowing he can't kill the young nephilim. After a while, Jack tells him about how he and his brother have been targeting people, and that Kabaiel was feeding off children's souls. He raises his sword and asks how Jack knew that, and he replies that Death told him. Upon arrival, Castiel battles against Kabaiel and kills him, leaving the grigori extinct.
Jack reveals to Castiel and the Winchesters that he was targeting the grigori to consume their hearts and eventually become powerful enough to kill God.
