Maxime Dassier is a midfielder for Inakuni Raimon, the team formed from players of the remote Inakuni Island who transfer to Raimon Junior High to compete in the Football Frontier tournament. He originally served as the captain of the Inakuni Island soccer team and holds a physically imposing presence, being tall and muscular with slightly tanned skin, long brown hair with straight bangs, and light brown eyes.

In terms of personality, Maxime appears as a calm and dependable teammate, whose experience as a former captain brings a sense of stability to the group. He is cooperative and willing to work with others to execute complex plays, showing a practical and supportive attitude on the field. His motivations align with the collective goal of Inakuni Raimon: to secure a sponsor, keep their club alive, and prove their strength against stronger opponents from the mainland.

Within the story, Maxime fills the role of a solid midfielder who contributes both defensively and in building up attacks. He does not stand out as a primary protagonist but remains a consistent supporting presence throughout the team’s journey. He also appears in the sequel series Inazuma Eleven: Orion no Kokuin, where he continues as part of the broader national selection.

His most notable ability is a combined shooting technique performed with Kiko Calavente. The two execute a coordinated dance-like sequence that ends with Maxime throwing Kiko, who then kicks the ball into the goal. This technique was originally developed with Adriano Donati in mind, but Maxime ultimately found greater success and synergy with Kiko when executing it during matches. His physical stature also gives him an advantage in aerial challenges and physical play, though specific individual special moves are not prominently highlighted. Over the course of the series, he grows by adapting to the higher level of competition and deepening his understanding of team-based combination strategies.
