The Shadowpact is a fictional group of magic-based heroes who fought against the Spectre in the 2005 limited series Day of Vengeance, published by DC Comics.

[3] The group is founded on a spur of the moment impulse by Enchantress, Ragman, and Detective Chimp to get rid of the Spectre because of his decision to destroy all magic in the universe.

[6] In their fight with the Spectre, the group is aided by others such as the Phantom Stranger, who advises Detective Chimp when he has been transformed into a rodent; Captain Marvel; the wizard Shazam; and Black Alice.

Black Alice, after witnessing the final battle on the Rock from afar with the Shadowpact, leaves to be with her father in Dayton, Ohio, without formally joining the team.

In Day of Vengeance: Infinite Crisis Special #1, the Shadowpact members join other magic users in trying to rebuild the Rock of Eternity after it shatters over Gotham City.

After capturing Greed, Nightshade is attacked and abducted by Felix Faust and the Demons Three, who deliver her to Alexander Luthor Jr., who incorporates her into his multiverse power battery.

Making it to the Rock, Nabu has time before he dies to explain to the heroes what has happened to the Spectre, and to charge Detective Chimp with choosing a new Doctor Fate.

In his magical imprisonment, the White Rabbit proposes to free the Shadowpact members so that the Nightmaster hones his skills and meet him on a future match.

[8] In their next storyline, the members of the Shadowpact have found themselves targeted by a whole host of villains including Blue Moon, the Wild Huntsman, and the Congregation.

[9] With help from Madame Xanadu, they manage to cure their blinded teammates and, despite all their recent troubles, the Shadowpact now find themselves in a stronger position in the magical order.

[11] In the final storyline before the book was cancelled, the Phantom Stranger brings the Shadowpact teams of 1908 and 2108 to the present in order to combat the Sun King, revealed as the power behind Doctor Gotham.

In the final battle, various Shadowpact teams from throughout history are united, fighting the Sun King in multiple time zones simultaneously.
