Autovac Mattie is a robotic combatant from the anime Fight League: Gear Gadget Generators, fighting with the Boltechs team. Originally engineered for cleaning duties, she received combat modifications that enhanced her battle capabilities while preserving her core functionality. Her design features orange pigtails and non-functional goggles integrated into her battle gear.

Mattie exhibits a cheerful, responsible personality, maintaining pride in her cleaning origins through battlefield humor about tidying opponents. She reliably services teammates' equipment, reflecting systematic diligence. Personality assessments classify her as an ENFJ and Enneagram 6w5, emphasizing loyalty, anxiety during uncertainty, and a need for security.

In combat, she primarily rams foes using her autovac frame and transforms into a sphere for swift evasion. Her documented techniques include executing the "Art Chain" maneuver cooperatively. Mid-series, Mattie undergoes a Style Change evolution into "Jetvac Mattie," gaining enhanced abilities without altering her core identity.

As a Boltechs secondary combatant, she follows tactical directives from leader G-Wrench. She consistently engages teammates with energetic enthusiasm during matches and post-fight analyses. Her combat role, functions, and background remain unchanged across all documented media.
