Brainiac (Vril Dox) is a supervillain appearing in American comic books published by DC Comics. Created by Otto Binder and Al Plastino, the character debuted in Action Comics #242 in July 1958.[1] He is usually depicted as an extraterrestrial android or cyborg who serves as one of Superman's greatest enemies and a frequent adversary of the Justice League. Brainiac is known for shrinking and stealing Kandor, the capital city of Superman's home planet Krypton, and is even responsible for Krypton's destruction in some continuities.

The character's name is a portmanteau of the words brain and maniac.[2] In 2009, Brainiac was ranked by IGN as 17th Greatest Comic Book Villain of All Time.[3] He has been substantially adapted into various forms of media, having been voiced by Corey Burton in various television shows set within the DC animated universe, by John Noble in animated film Superman: Unbound, and by Jeffrey Combs in the video game Injustice 2. In live-action television, Brainiac has been portrayed by James Marsters on Smallville and by Blake Ritson on Krypton.

The first Brainiac/Kandor comic book story in Action Comics #242 (July 1958) was based on a story arc in the Superman comic strip from April through August 1958. In the comic strip story, Superman's foe was named Romado, who traveled the cosmos with a white alien monkey named Koko, shrinking major cities and keeping them in glass jars. The strip's Kryptonian bottled city was named Dur-El-Va.[4] This cross-continuity conflict was not unprecedented; in 1958 and '59, editor Mort Weisinger used the comic strip to prototype a number of concepts that he planned to introduce in the book, including Bizarro and red Kryptonite.[5]

Brainiac is a bald, green-skinned humanoid who arrives on Earth and shrinks various cities, including Metropolis, storing them in bottles with the intent of using them to restore the then-unnamed planet he ruled.[6] He was originally notable only for having shrunk the bottle city of Kandor with his shrinking ray and for using a force field.[7] In his initial story, he also traveled with a white alien monkey named Koko; the monkey also appears in a 1960 Superman story retelling the story of Kandor's disappearance (Superman #141 (November 1960)). Koko was quickly dropped from Brainiac's stories, but a version of the monkey has made sporadic appearances as the villain's pet in the series Justice and the 2008 storyline "Brainiac" in Action Comics. The villain's descendant Brainiac 5 also had a pet named Koko for several stories in the 1990s.
