The central characters, Kaneda and Tetsuo, are members of a biker gang known as the Capsules. This gang culture is characterized by its distinctive sense of camaraderie, hierarchy, and defiance. The Capsules, along with their rival gang, the Clowns, dominate the streets of Neo-Tokyo, engaging in violent skirmishes and high-speed chases. These gangs are not merely vehicles for action sequences; they are a manifestation of the broader societal breakdown and the desperation of a generation that feels abandoned by those in power.

The biker gangs in Akira reflect the angst and rebellion of youth who find themselves alienated from a society that has failed to provide them with meaningful opportunities or a sense of purpose. This is particularly evident in the character of Tetsuo, whose transformation from a gang member to a powerful, yet unstable, psychic being underscores the dangers of unchecked authority and the consequences of societal neglect. Tetsuo's struggle for control and identity mirrors the gang's collective struggle against a corrupt system that seeks to suppress their individuality and freedom.

The aesthetics of biker gang culture also play a significant role in Akira. The film's striking visuals, characterized by neon-lit streets, futuristic motorcycles, and gritty urban landscapes, create an atmosphere of anarchic energy and tension. The iconic red motorcycle ridden by Kaneda becomes a symbol of freedom and rebellion, embodying the spirit of the gang culture that permeates the film. The dynamic animation and meticulous attention to detail in the depiction of motorcycle chases and gang confrontations enhance the film's sense of urgency and chaos.

Additionally, the camaraderie within the biker gang provides a counterpoint to the isolation and alienation experienced by the characters. The gang members share a bond that, despite the violence and volatility of their environment, offers a semblance of belonging and identity. This sense of unity stands in stark contrast to the fragmented and corrupt society around them, highlighting the human need for connection and community amidst turmoil.
