Brainiac (Vril Dox) is a supervillain appearing in American comic books published by DC Comics. Created by writer Otto Binder and artist Al Plastino, Brainiac first appeared in Action Comics #242 (1958), and has since endured as one of Superman's greatest enemies.

Brainiac is commonly depicted as a superintelligent android or cyborg from the planet Colu who is obsessed with collecting all knowledge in the known universe. He travels the galaxy and shrinks cities to bottle size for preservation on his skull-shaped spaceship before destroying their source planets, believing the knowledge he acquires to be most valuable if he alone possesses it. Among these shrunken cities is Kandor, the capital of Superman's home planet Krypton, and Brainiac is even responsible for Krypton's destruction in some continuities. Regarded as one of the most dangerous threats in the DC Universe, Brainiac has come into repeated conflict with Superman and the Justice League. Although stories often end in Brainiac's apparent destruction, the character's artificial consciousness is resurrected in new physical forms, some robotic and others more organic-based in appearance.

The Legion of Super-Heroes is a superhero team appearing in American comic books published by DC Comics. Created by writer Otto Binder and artist Al Plastino, the Legion is a group of superpowered beings living in the 30th and 31st centuries of the DC Comics Universe, and first appeared in Adventure Comics #247 (April 1958).

The team is closely associated with the original Superboy character (Superman when he was a teenager) and in their first appearances was portrayed as a group of time travelers. Later, the Legion's origin and back story were fleshed out, and the group was given its own monthly comic.

Supergirl is an American superhero drama television series developed by Ali Adler, Greg Berlanti and Andrew Kreisberg that aired on CBS from October 26, 2015 to April 8, 2016, and later The CW from October 10, 2016 to November 9, 2021. Based on the DC Comics character created by Otto Binder and Al Plastino, the series follows Kara Zor-El (played by Melissa Benoist), Superman's cousin, and one of the last surviving Kryptonians from the planet Krypton. As Supergirl, Kara uses her powers to protect National City. The series was retroactively incorporated into the Arrowverse beginning with its second season, and became definitively linked with the rest of the franchise in the fifth season.

The series was officially picked up on May 6, 2015, after receiving a full series commitment in September 2014. Following a full season order on November 30, 2015, it transitioned to The CW for its second season going forward.

Alfred John Plastino (December 15, 1921 – November 25, 2013) was an American comics artist best known as one of the most prolific Superman artists of the 1950s, along with his DC Comics colleague Wayne Boring. Plastino also worked as a comics writer, editor, letterer, and colorist.

With writer Otto Binder, he co-created the DC characters Supergirl and Brainiac, as well as the teenage team the Legion of Super-Heroes.

The Monster Society of Evil is a supervillain team created by Otto Binder and C. C. Beck for Fawcett Comics. It is led by Mister Mind against their mutual enemy Captain Marvel. The team is significant as one of the first supervillain teams in comics to contain villains that a superhero had fought previously; prior to this, supervillain teams were composed of villains created just for that storyline. In fact, the Monster Society consists of every major enemy Captain Marvel had ever faced.

The Monster Society of Evil made its debut in Captain Marvel Adventures #22, and the resulting "Monster Society of Evil" story arc continued for two years in Captain Marvel Adventures, ending with issue #46 (May 1945).

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.

Mister Mind is a supervillain appearing in American comic books published by DC Comics, primarily as an enemy of Captain Marvel. Created by Otto Binder and C. C. Beck for Fawcett Comics, the character made a cameo appearance in Captain Marvel Adventures #22 (March 1943) before making his full first appearance in Captain Marvel Adventures #26 (August 1943). Mister Mind is a two-inch alien caterpillar-like being of high intelligence with telepathic powers who usually carries out his villainous plans through an organization called the Monster Society of Evil. The Society made its debut in Captain Marvel Adventures #22, and the resulting "Monster Society of Evil" story arc continued for two years in Captain Marvel Adventures, ending with issue #46 (May 1945).

Mister Mind appears in the DC Extended Universe films Shazam! and Shazam! Fury of the Gods, portrayed in CGI and voiced by director David F. Sandberg.

Mary Marvel, also known as Lady Shazam and Shazam, is a superheroine originally published by Fawcett Comics and now owned by DC Comics. Created by Otto Binder and Marc Swayze, she first appeared in Captain Marvel Adventures #18 (cover-dated Dec. 1942). The character is depicted as a female counterpart of Shazam, being among the earliest of female counterparts of male superheroes, while often empowered by different set of patrons.

While the character's alter-ego is Mary Bromfield, her background and histories have varied over time; older stories have commonly depicted her as the twin sister of Billy Batson (birth name Mary Batson) separated at a young age following their parents' demise, ending up adopted by the Bromfield family. When reunited with her brother, she discovers powers similar to his and becomes a hero and protector of Fawcett City. At one point in time, the character also developed into a more antagonistic role as Black Mary. Following the New 52 reboot, she is instead cast as a victim of abusive parents who ran away from her family and is adopted by the Vazquez family. She later becomes the foster sister of Billy Batson, Freedy Freeman, and others wherein all become empowered and are part of the superhero family, the Shazam Family.
