Cyborg in the context of Biomechatronic

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.

Science fiction (or sci-fi) is a film genre that uses speculative, science-based depictions of phenomena that are not fully accepted by mainstream science, such as extraterrestrial lifeforms, spacecraft, robots, cyborgs, mutants, interstellar travel, time travel, or other technologies. Science fiction films have often been used to focus on political or social issues, and to explore philosophical issues like the human condition.

The genre has existed since the early years of silent cinema, when Georges Méliès' A Trip to the Moon (1902) employed trick photography effects. The next major example (first in feature-length in the genre) was the film Metropolis (1927). From the 1930s to the 1950s, the genre consisted mainly of low-budget B movies. After Stanley Kubrick's landmark 2001: A Space Odyssey (1968), the science fiction film genre was taken more seriously. In the late 1970s, big-budget science fiction films filled with special effects became popular with audiences after the success of Star Wars (1977) and paved the way for the blockbuster hits of subsequent decades.

The Evangelions (エヴァンゲリオン, Evangerion), also referred to as Evas, are fictional biomechanical humanoid mechas introduced in the anime television series Neon Genesis Evangelion, produced by Gainax and directed by Hideaki Anno and in the manga of the same name written and illustrated by Yoshiyuki Sadamoto. In addition to the original animated series, Evangelions appear in its derivative works, including spin-off manga, video games, visual novels, the original video animation Petit Eva: Evangelion@School, and in the Rebuild of Evangelion movies, with considerably different roles and guises.

In the original animated series, the Evangelions are giant humanoids, which the research center Gehirn and the special agency Nerv research to fight beings called Angels. They have mechanical components and a basic organic structure derived from Adam and Lilith; for this reason, they have eyes, epidermis, internal organs, and nails similar to those of humans and have been classified as cyborgs rather than mecha in the traditional sense. Those assigned to pilot an Evangelion are called Children and are selected by an organization called the Marduk Institute. Their designs, inspired by the oni of Japanese folklore, Ultraman, Iczer-One, Devilman, and other sources, caused problems during the production of the animated series but have received a positive reception from critics and audiences and have been used for merchandise.

Sojourn is the codename of Vivian Chase, a character in the Overwatch media franchise. She first appeared in Overwatch 2, a first-person hero shooter video game developed by Blizzard Entertainment, being added to game's playable character roster upon its early access release in 2022 and was voiced by Cherise Boothe. Initially designed by Arnold Tsang in 2014, Sojourn is a "Damage"-class hero that uses cybernetic enhancements to handle the recoil of her primary weapon; a railgun. In the franchise's lore, she is a Canadian soldier who serves at the rank of captain within the Overwatch team, previously working with Jack Morrison during the Omnic War and commanded agents or provided long-range cover.

Sojourn garnered mixed reception upon her inclusion, with critics praising her cybernetic design and representation of afro-textured hair, whilst others critiquing lack of uniqueness and lore in-game. Particular scrutiny was directed towards Sojourn as a representation of black female in videos, with critics deriding her inclusion as disappointing and bare-minimum; stemming from a long tracked history of criticism directed at Blizzard for the lack of black women representation in the franchise.
