Marina Ohgami, daughter of Dr. Ogami (rival to Dr. Tsuchiya in Mini 4WD science), appears as an anime-original character in *Bakusou Kyoudai Let's & Go! MAX*. The Borzoi Academy's capture of her father, whom she idolizes as her sole parent, fuels her mission to defeat the organization and free him. Borzoi promotes destructive battle racing tactics.

She possesses amethyst eyes and reddish-brown hair worn in two ponytails secured by green hairbands. Her typical attire is a pink sleeveless tank top revealing her midriff, green shorts, and sometimes a yellow jacket. Marina pilots the battle-oriented Fire Stinger Mini 4WD, based on her father's Ray Stinger, later upgrading to the Phoenix Stinger. These cars reflect her aggressive style against Borzoi-associated racers.

Intensely serious with minimal outward emotion, Marina pursues her mission with single-minded focus, displaying competitiveness towards Borzoi affiliates. This often brings her into conflict with former Borzoi students Gouki and Retsuya Ichimonji. Despite clashes, she forms a complex dynamic with them, cooperating against common enemies while maintaining rivalry. Gouki persistently misnaming her "Mariko" consistently annoys her.

Internally, Marina grapples with conflicting views on battle racing. Initially aligned with her father's destructive principles, her experiences prompt her to question these methods and uphold her own ethics. This struggle intensifies when obeying her father's order to destroy Gouki's Max Breaker using her Phoenix Stinger, demonstrating loyalty even as her convictions evolve. Her arc centers on resolving this conflict while pursuing her goal of reuniting with Dr. Ogami.

Her narrative concludes within the MAX season, focusing on dismantling the Borzoi Academy's influence and freeing her father.
