Sigma Biker 4

Sigma Biker 4 is a white & blue auxiliary Sigma Runner modeled after a police motorcycle and rider.

Overview
In its Attack Mode, the front wheel detaches so it can attack like a yo-yo. When used in a Sigma Boost, it allows the user to fire a Biker Suppression Shot, where the user fires an energy blast in the shape of a wheel. This attack can be enhanced using the power of other pieces in the Lupin Collection.
