History
Dagger was the leader of the Outcasts and was punishing Gambit for his sins against their group when she was challenged to a fight to the death by Bloodstorm. She lost, and it came out that Cloak and Dagger had continued to mutate until they became one person. Due to the agony they were in, Cloak and Dagger chose to kill themselves by imploding inside Cloak's cloak.[1]
