Mannakka is one of King Ivalda's three primary generals in the Mecha Empire, leading Earth invasion forces under his command. Her strategy relies on deception and subterfuge, contrasting with fellow generals Uyokka's brute force and Sayokka's cunning.

She utilizes specific combat abilities, firing blue finger lasers and executing high jumps during battle. A key tactic involves adopting human disguises for covert infiltration and manipulation.

In episode 30, Mannakka takes command of a specialized unit of female Sentry Robots, coordinating their operations alongside the commander Professor Queen. This unit deploys hand energy beams on missions, though their combat role remains secondary to Mannakka's focus on psychological and deceptive warfare.
