Lalaco Godspeed is a notorious space pirate and the mother of the protagonist, Luluco. She is the ex-wife of Keiji, Luluco's father, and serves as the main antagonist in the early part of the series. Her appearance is striking: she has scarlet hair, turquoise eyes, and wears a risque pirate outfit that emphasizes her flamboyant and theatrical nature. As the captain of a league of villainous space pirates, her primary motivation is to take over Ogikubo, the solar system district where her daughter lives. She devises a plan to auction off the entire district to the highest bidder, placing her in direct conflict with the Space Patrol.

Personality-wise, Lalaco is bold, reckless, and supremely confident. She revels in chaos and refuses to be bound by any law or convention. Her alias, "Godspeed," reflects her overwhelming power and her willingness to disregard rules. Initially, she is condescending and dismissive toward Luluco, even telling her not to refer to her as "mother." However, as the story progresses and Luluco demonstrates newfound strength and courage, Lalaco's demeanor shifts. She begins to show a grudging fondness and pride in her daughter, marking a notable development from a cold, distant figure to one who can appreciate her child's growth.

In the story, Lalaco appears as a supporting character and primary antagonist whose actions drive a major arc: her attempt to sell Ogikubo forces Luluco and the Space Patrol to intervene. Key relationships include her strained ties with Luluco and her ex-husband Keiji, though her pirate crew also serves as a backdrop for her leadership. Her notable ability is the "God Pirate's Gun Morphing," a power that allows her to transform parts of her body into a gun, similar to the gun-morphing abilities used by the Space Patrol. This makes her a formidable combatant and a direct counterpart to the heroes. Over the course of the series, she evolves from a self-serving criminal into a figure who, while still a pirate, acknowledges and respects her daughter's strength.
