Mario

Mario is a mysterious warrior, or plumber, or warrior-pumber who has spent some time in a place known as the Mushroom Kindgom. He is also a participant in the Grand Combat. Mario is the titular character of the Mario Bros. series, and is a recurring minor character in Paradox Fighters.

He's a bit odd.

Personality
Mario is a cooperative fellow who will eagerly work as part of a team. Winning is not his primary concern, as he has readily surrendered to another team at least once.

Trivia

 * No one knows his last name. Some have speculated that it might also be Mario, but that'd be crazy.
