Sheri

Sheri is a playable character in the game Mario Tennis: Power Tour for the Game Boy Advance. She is one of several human characters created exclusively for the Mario Tennis series. Sheri is an all-around-type character with pale skin and flaming red hair. She wears a black and red jumpsuit with black shoes. Her doubles partner is Willy, and together, they play and defeat Elroy and Tori in semifinals at the Island Open. After beating Elroy and Tori, they go on to play Clay and Ace. The player never faces her in the singles tournament.

Although she expresses the utmost confidence in Willy (and for good reason), the two of them do not act like a couple, unlike Elroy and Tori.
