The group known as Genesis Gang appears in the 2001 Japanese horror film Suicide Club, serving as the followers and accomplices of the charismatic and disturbed leader Muneo Suzuki, who calls himself Genesis. This ensemble is depicted as a small, dedicated collective of young individuals who assist Genesis in his crimes, which include kidnapping, torture, and murder. Members are identified in the film's cast as Masato Tsujioka, Kôsuke Hamamoto, and Kei Nagase, and the group also includes a figure referred to as a slave boy named Joshua.

The personality of the group as a whole is one of detached, ritualistic devotion to their leader. They are not depicted as mere thugs but as a kind of warped rock band or artistic collective, reflecting Genesis's self-aggrandizing persona. He claims to be the Charlie Manson of the information age, and his gang members appear to be under his spell, participating in his violent fantasies with a disturbing sense of purpose and theatricality. Their motivations are rooted in a shared, nihilistic ideology centered on death, spectacle, and the allure of a digital-age suicide cult. They run a website promoting this philosophy and abduct victims to subject them to horrific experiences in a place Genesis calls the pleasure room. Their role in the story is to act as the physical enforcers of Genesis's will, creating an atmosphere of terror that complements the film's broader mystery of a nationwide suicide epidemic.

In their key scene, the gang holds a young hacker named Kiyoko captive in a bowling alley. While Genesis performs a song, one of his gang members rapes and kills another young woman, showcasing their complete moral vacuum and their function as instruments of their leader's depraved performances. Their primary relationship is with Genesis, who they follow with the loyalty of cult members. Kiyoko serves as their primary victim and the means by which the police eventually locate them. The gang does not undergo significant development, remaining a static representation of cult-like evil. However, their leader’s ultimate goal is not to escape but to achieve notoriety, so he allows Kiyoko to send their location to the police, leading to their arrest.

There are no notable supernatural or extraordinary abilities associated with the Genesis Gang. Their power comes from their collective anonymity, their leader's manipulative philosophy, and their willingness to commit brutal acts of violence, which they carry out with a chilling, rock-and-roll aesthetic. They are a group defined by their worship of Genesis and their participation in his quest for infamy through terror.
