Daggers of light
Dagger appear in the third season of the Ultimate Spider-Man cartoon series.
Cloak was possessed by Dormammu as part of a plot to capture Doctor Strange, Iron Fist, and White Tiger in a plot to power the Siege Perilous and invade Earth. With help from Dagger, Spider-Man was able to free Cloak from Dormammu's possession. Cloak and Dagger then help Spider-Man free Doctor Strange, Iron Fist, and White Tiger and defeat Dormammu. They were supposed to be two of Spider-Man's recruits for his new team of superhero "warriors". They originally turned down the offer, having been recruited by Taskmaster who claimed to Cloak and Dagger that no one can be trusted.
In the episode "New Warriors", Cloak and Dagger appear as members of Taskmaster's Thunderbolts alongside Vulture. Taskmaster had Cloak "thin the herd" by transporting Power Man, Iron Fist, White Tiger, and Nova to a deserted island. Cloak and Dagger switched sides after Spider-Man saved Cloak after Taskmaster refused to and the two of them found out Taskmaster can not be trusted and joined Spider-Man's team by the end of the episode.
