Flit

Flit is a character in Mario Tennis: Power Tour. Though unranked in singles, he holds the third rank in Varsity doubles at the Academy. He takes tennis very seriously and expresses great determination to rise through the ranks. He's generally a very sour person, but he still accepts defeat when he and Emi lose their ranking match against Clay and Ace. When going through singles, he is partnered with Skipper, but his intense practice encourages Skipper to switch partners. He is very proud of his power shot, which happens to be the Slider Shot. His grouchiness may stem from losing his ranking. It's implied based on conversations about someone being so disoriented that they lost their ranking after using the malfunctioning Swift Spin and the fact that Flit's power shot is spin-based and that Flit states that he lost his rank to Paula (claiming it as a fluke) that Flit was the varsity player the person was talking about.
