The Neon Vipers are a Circuit street gang of about 90 members known for two things: speed and flash. In a neighborhood full of criminal organizations that project menace through bulk and brutality, the Vipers project it through velocity — augmented reflexes, modified motorcycles, and a hit-and-run operational style that makes them nearly impossible to pin down.

The gang's core activity is smash-and-grab robbery: high-speed raids on delivery vehicles, warehouse loading docks, and retail establishments where the Vipers strike fast enough that security systems don't have time to respond and vanish into the Circuit's dense traffic before pursuit can organize. Their augmented reflexes (most members have reaction-enhancement implants) and custom vehicles (stripped-down motorcycles modified for maximum acceleration) make them the fastest criminal outfit in the city.

The Vipers' secondary business is racing — illegal augmented-vehicle races through the Circuit's streets that draw betting crowds and generate income through entry fees and gambling. These races serve double duty as recruitment events: prospective Vipers must complete a race without crashing, and the races themselves are the Vipers' most effective marketing tool, drawing young Circuit residents who want the speed and the flash and the feeling of being alive in a way that working a corporate job never provides.
