A Bat Family Crossover between Animal Man, Swamp Thing, and Frankenstein: Agent of S.H.A.D.E. that took place in the New 52 between October 2012 and May 2013. It features the efforts of the Green and the Red to stop the Rot, from killing all life on Earth.
This crossover has examples of the following tropes:
- Bat Family Crossover: For the most part, this just involves those directly connected to the Red, the Green, or the Rot, with some tie-ins from Frankenstein: Agent of S.H.A.D.E..
- Big Bad Duumvirate: Anton Arcane and the Parliament of Decay. Becomes a Big Bad Ensemble toward the end.
- Body Horror: Anything involving the Rot. The Green and the Red aren't exempt either.
- Brainwashed and Crazy: A great many "rotten" characters, heroes who are controlled by the Rot.
- Dark Is Not Evil: In the end, it turns out the Rot isn't evil, just an essential aspect of life. The Parliament of Decay actually doesn't like any of Anton's antics, and even send Alec and Buddy back in time to save the world and stop Anton. Abigail ends up becoming the new Avatar of Decay (a good one this time), but remains loving of the avatar of the Green.
- Enemy Mine: Multiple villains join forces with the heroes to try to stop the Rot. The Rot's Parliament of Decay joins forces with Swamp Thing to stop Anton Arcane at the end, though they were never evil to begin with.
- Green Thumb: Aside from Swamp Thing, Poison Ivy and the Floronic Man also show up to support the heroes.
- Heroic Sacrifice: Abogail lets herself be killed to become the new Avatar of Decay so that her uncle will be killed completely.
- Make Them Rot: What the Rot does.
- Omnicidal Maniac: Subverted. The Rot doesn't want to destroy all life, but to conquer it. After all, there can't be decay without life.
- Our Ghosts Are Different: Deadman is a member of the cast.
- Powered Armor: Steel's Metal-Zero Armor.
- Purple Is Powerful: Black Orchid, who is connected to both the Red and the Green.
- Rewarded as a Traitor Deserves: Anton Arcane is killed by the Parliament of Decay for betraying them once they get a new avatar in the form of his niece.
- Star-Crossed Lovers: Swamp Thing and Abigail Arcane as of the end of the crossover, due to her influence rotting the Green, meaning that they cannot be near each other lest their opposing influences cause harm to one another.
- Super Team: The Justice League Dark makes an appearance, as do the "Ravagers" and the Teen Titans.
- Taking You with Me: Anton Arcane tries this with Swamp Thing in the finale. Ultimately, he does kill Alec Holland, but his spirit remains as the Swamp Thing regardless.
- Together in Death: Abigail Arcane and Alec Holland, courtesy of the Avatar of Decay version of Abigail's efforts.
- Voluntary Shapeshifting: Due to his connection to the Red, Beast Boy shows up.
- What the Hell, Hero?: John Constantine blames Buddy Baker for what happened with the Rot, since he didn't work as the Red's Animal Man when it was necessary in order to keep the weak Avatar of the Red safe until necessary.
