The Queen in Black storyline prompted Iron Man to organize two strike teams to do battle against Hela. Led by Iron Man, Team Dark included Agent Anti-Venom, Cable, Darkstar and Cloak. Team Light, on the other hand, included Beta Ray Bill, Photon, Sunfire and Dagger. Each issue of the limited series displays the classic Defenders nameplate on the cover, but Iron Man's passing reference to the teams as Earth's Defenders seemed incidental (#1).
I purchased this edition of Defenders of Light and Dark #1 (September 2026) with a variant cover featuring Cable and Cloak.
