Bobby Max

Nicknamed the Beast Bulldozer, Bobby is the tallest and most muscularly developed of his fellow teammates. A skilled former baseball, basketball and American football player, Bobby struggles (often unsuccessfully) to control his temper and poor sportsmanship that have gotten him banned from most sports in his school. Baker convinces Bobby to try tennis after he causes his school's football team to be suspended.

In the Junior Invitational match against Yamabuki Middle School junior Kiyosumi "Lucky" Sengoku, Bobby employs a combination of skills from his prior sports experience, including a shot that mimics a football three-point stance, and a mastery of his build and athleticism as his primary techniques.

Bobby continues to struggle within the game with his poor sportsmanship. He argues with the referee over every point Sengoku scores, and nearly destroys his racquet after a call. Baker spends most of the match trying to calm Bobby's temper. However, his efforts are in vain after neither player can continue the match, and the game is declared No Game.
