BQ arises from Abraham's awakening within the first hero, Baba Lamune's body. This entity supplants PQ as the advisor robot for the antagonist forces. BQ serves Abraham directly, assuming command over the subordinate villains Narcissist Dandy and Pheromone Lip. The character serves as the direct conduit for Abraham's authority, issuing orders to these minions to advance the core objective of resurrecting and serving the demon god.

BQ's existence is intrinsically linked to Abraham's control over the possessed Lamuness I. The character's role centers on coordinating tactical operations and ensuring the comic relief villain duo executes Abraham's destructive agenda. BQ operates within Abraham's command structure, acting as the primary intermediary between the main antagonist and his field operatives.

BQ does not appear in the sequel OVA "VS Knight Ramune & 40 FRESH" or other spin-off media. The character ceases operation following Abraham's defeat and separation from the first Lamuness' body.
