DC Rebirth in the context of "Thomas Wayne"

The Suicide Squad is an antihero/supervillain team appearing in American comic books published by DC Comics. The first version of the Suicide Squad debuted in The Brave and the Bold #25 (September 1959) and the second and modern version, created by John Ostrander, debuted in Legends #3 (January 1987).

Various incarnations of the Suicide Squad have existed throughout the years as depicted in several self-titled comic book series, from its origins in the Silver Age to its modern-day post-Crisis re-imagining, to the New 52 version and the current version that was introduced during DC Rebirth in 2016. Though the roster has changed considerably over the years, some of its best-known members include Rick Flag, Captain Boomerang, Deadshot, Bronze Tiger, King Shark and Harley Quinn.

"The Button" is a 2017 comic book crossover created and published by the comic book publishing company DC Comics. The story arc consists of four issues from DC's Batman and Flash publications, functioning in part as a larger buildup towards the "Doomsday Clock" event. The plot was written by Joshua Williamson and Tom King, with art by Jason Fabok and Howard Porter.

In the story, Batman and Flash work together to uncover the truth behind the mysterious button found in the Batcave. As the investigation unfolds, the secrets of the Button bring about the wrath of Professor Zoom as well as the unknown orchestrator of DC Rebirth.

Jason Peter Todd is a fictional character appearing in American comic books published by DC Comics. First appearing in Batman #357 in March 1983, he was created to succeed Dick Grayson as Robin, Batman's partner and sidekick. He initially shared a similar origin to Grayson, being the son of circus acrobats who were killed by criminals in Gotham (Dick's were killed by a local mob boss who sabotaged their trapeze while Jason's parents were killed by Killer Croc) and adopted by Bruce Wayne, Batman's alter ego, as his son and protégé. Following the Crisis on Infinite Earths event and the rebooting of DC's main comics universe, Jason's origin was changed to being a pre-teen street urchin and petty thief whom Bruce adopted and mentored after finding the boy attempting to steal the tires off the Batmobile. This origin has since become the standard for subsequent iterations of the character.

Following Max Allan Collins's revamping of Todd's origin story in Batman #408–411, the character was written by Jim Starlin, who had him become increasingly aggressive and reckless. This led DC Comics to conduct a telephone poll concerning the 1988 storyline "A Death in the Family" to determine whether the character should die at the Joker's hands. The poll ended with a narrow majority of votes in favor of killing Todd, resulting in his death. Subsequent stories dealt with Batman's guilt over failing to save him. The character was resurrected in the 2005 "Under the Hood" story arc, which saw him become a murderous villain known as the Red Hood. In the current New 52/DC Rebirth continuity, Todd is a more nuanced antihero who maintains a tense, albeit partially mended, relationship with Batman and has been accepted as a full member of the Batman family.

Poison Ivy is a character appearing in American comic books published by DC Comics. Created by writer Robert Kanigher, Sheldon Moldoff and artist Carmine Infantino, she debuted in Batman #181 (June 1966) and has become one of the superhero Batman's most enduring enemies belonging to the collective of adversaries that make up his rogues gallery.

In her comic book appearances, Poison Ivy is depicted as a doctor of botany-turned-misanthropic ecoterrorist in Gotham City named Pamela Lillian Isley, PhD (/ˈaɪzli/ EYEZ-lee) with the ability to control all plant life. Empowered by an elemental force known as the "Green", Ivy attempts to protect the sanctity and supremacy of nature at all costs by lashing out against humanity, which brings her into conflict with Batman. While usually portrayed as a supervillain, Ivy has also been an antiheroine at times as well as the primary love interest of Harley Quinn as of The New 52 and DC Rebirth relaunches. A one-piece costume adorned with leaves and vines serves as Poison Ivy's visual motif.
