The Arrowverse is an American superhero media franchise and shared universe that is centered on various interconnected television series based on DC Comics superhero characters, primarily airing on The CW as well as web series on CW Seed. The series were developed by Greg Berlanti, Marc Guggenheim, Andrew Kreisberg, Geoff Johns, Ali Adler, Phil Klemmer, Salim Akil, and Caroline Dries. Set in a shared fictional multiverse much like the DC Universe and DC Multiverse in comic books, it was established by crossing over common plot elements, settings, cast and characters that span six live-action television series and two animated series.

The franchise began with Arrow, based on the character Green Arrow, which debuted in October 2012. It was followed by The Flash in 2014, and the animated web series Vixen in 2015. The franchise further expanded in January 2016 with the debut of Legends of Tomorrow, starring characters who previously appeared on both Arrow and The Flash. Later that year, the CBS series Supergirl, having already crossed over with The Flash, moved to The CW for the remainder of its run. A second animated web series, Freedom Fighters: The Ray, was released in 2017, which followed Ray Terrill / The Ray, who would make a live-action appearance during that year's crossover event "Crisis on Earth-X". In addition to the live-action and web-based series, the franchise has spawned three promotional tie-in live-action web series: Blood Rush, Chronicles of Cisco and The Flash: Stretched Scenes; released in 2013, 2016 and 2017 respectively. A fifth series, Batwoman, premiered in 2019. Six ensemble crossover events involving many of the live-action series of the Arrowverse have taken place, beginning with "Flash vs. Arrow" in 2014 and concluding with "Crisis on Infinite Earths" between 2019 and 2020. Additionally, Matt Ryan has reprised his role as John Constantine from the NBC series Constantine, initially in guest appearances in episodes of Arrow and Legends of Tomorrow, before becoming a series regular for the latter, in addition to continuing storylines from the former series. In 2023, the franchise concluded with the ninth and final season of The Flash.

Adventure Comics is an American comic book series published by DC Comics from 1938 to 1983 and revived from 2009 to 2011. In its first era, the series ran for 503 issues (472 of those after the title changed from New Adventure Comics), making it the fifth-longest-running DC series, behind Detective Comics, Action Comics, Superman, and Batman. The series was revived in 2009 through a new "#1" issue by artist Clayton Henry and writer Geoff Johns. It returned to its original numbering with #516 (September 2010). The series ended again with #529 (October 2011) prior to a company-wide revision of DC's superhero comic book line, known as "The New 52".

"Flashpoint" is a 2011 comic book crossover story arc published by DC Comics. Consisting of an eponymous core limited series and a number of tie-in titles, the storyline premiered in May 2011. The core miniseries was written by Geoff Johns and pencilled by Andy Kubert. The series radically changes the status quo for the DC Universe, leading into the publisher's 2011 relaunch, The New 52.

Flashpoint details an altered DC Universe in which only Barry Allen seems to be aware of significant differences between the regular timeline and the altered one, including Cyborg's place as the world's quintessential hero, much like Superman is in the main timeline, with Superman himself being held captive as a lab-rat by the United States government within an underground facility in Metropolis. In addition, Thomas Wayne is Batman, and a war between Wonder Woman and Aquaman has decimated western Europe.

Black Adam (Teth-Adam) is a fictional character appearing in American comic books published by DC Comics. He was created by Otto Binder and C. C. Beck, and first appeared in the debut issue of Fawcett Comics' The Marvel Family comic book in December 1945. Since DC Comics licensed and acquired Fawcett's characters in the 1970s, Black Adam has endured as one of the most popular archenemies of the superhero Shazam and the Marvel Family alongside Doctor Sivana and Mister Mind.

Black Adam was originally depicted as a supervillain and the ancient magical champion predecessor of the champion Shazam, who fought his way to modern times to challenge the hero and his Marvel Family associates. Since the turn of the 21st century, however, Black Adam has been redefined by DC Comics writers Jerry Ordway, Geoff Johns, and David S. Goyer as an ancient Kahndaqi and corrupted antihero attempting to clear his name and reputation. He came from a fictional Middle Eastern country named Kahndaq, located at the southern tip of the Sinai Peninsula, and was portrayed as a hero who liberated his homeland from slavery. Featured roles in such comic book series as Justice Society of America, Villains United, Infinite Crisis, and 52 have elevated the character's prominence in the DC Universe, culminating with DC's 2021 line-wide Infinite Frontier relaunch, wherein he joins the Justice League. In 2009, Black Adam was ranked as IGN's 16th-greatest comic book villain of all time.
