Season 3: Web-Warriors

Cloak and Dagger

Dormammu gains control over Cloak so that he can capture Doctor Strange, Iron Fist, and White Tiger as part of a plot to power the Siege Perilous and lead the Mindless Ones into invading Earth. He takes control of the three but Spider-Man along with Dagger (who have managed to enter the Dark Dimension with the Cloak of Levitation and the Eye of Agamotto) are able to free Cloak, White Tiger and Iron Fist. Doctor Strange announces Dormammu's arrival and the demon appears before them making Spider-Man realize that they are no match for him. Dormammu becomes angry of his will being broken over the young heroes but pleasingly reveals that to him, it matters not and that they have no more use because he now possesses the Siege Perilous. He reveals that mere magic cannot send his army into other dimensions but the Siege Perilous is without limits. He demonstrates its power by disappearing and appearing behind the young heroes. He taunts that Spider-Man will burn with his friends. Dormammu along with Doctor Strange combine their powers to knock the young heroes away. Spider-Man reveals that if they are to escape, they'd need Doctor Strange back. White Tiger and Iron Fist tell him to go while they distract him. Iron Fist dodges Dormammu's fire before punching him but this has no effect on the demon. White Tiger scratches his leg but it has no effect on him either. Dormammu reveals that their abilities maybe impressive in their realm but in the Dark Dimension, they are nothing. He tries to burn them but they avoid it. However, this gives Spider-Man, Cloak and Dagger time to free Doctor Strange. Doctor Strange then uses the Eye of Agamotto to hurt Dormammu and it also causes an earthquake in the process. Spider-Man steals the Siege Perilous from Dormammu and the heroes escape the collapsing tower. Unfortunately, Dormammu gives chase to prevent them from escaping. He jumps to crush the heroes but Doctor Strange shields them. He then tries using his powers to destroy the shield. Spider-Man asks if the Siege Perilous can work before Doctor Strange reveals that it can't with Dormammu's power and that all the gateways between the Dark Dimension and their realm have been sealed shut. Cloak reveals that the only doorway that is not shut is the one inside him. White Tiger points out about how that can stop Dormammu from following them back and invading Earth. Cloak tries to persuade them to go before Doctor Strange reveals that he will seal Cloak up after he rejoins them back on Earth. Dormammu's powers succeed in breaking the shield but the heroes escape the Dark Dimension. Before Cloak can rejoin them, Dormammu grabs him and Cloak is trapped between the two realms. Dormammu uses this advantage to enter Earth's realm and he encounters the heroes again. He boasts that there is no escape from him before Spider-Man and Doctor Strange use magic to knock Dormammu back into the Dark Dimension before sealing Cloak up thus preventing Dormammu from invading Earth.
