Tori is a character from Mario Tennis: Power Tour. The player must unlock her by winning a match against her in singles mode. She is a technical player and her partner is Elroy. In singles mode, she is ranked three in Varsity courts and ranked one in doubles. Her power shot is the Control Shot.
In the Island Open, she expresses the utmost confidence about Elroy winning the singles tournament, and expresses similar sentiments amount her and Elroy winning the doubles tournament. In both cases, she behaves very arrogantly and speaks down to her fellow Academy players. In the doubles tournament, she and Elroy are defeated by Willy and Sheri in the semifinals. Afterwards, she briefly falls ill from shock, but has recovered by the time the final round is about to begin. When Clay or Ace visit her in the infirmary, she's becomes nicer and more respectful towards Clay and Ace than before.
Elroy and Tori interact and behave more like a couple than merely doubles partners. After being paired with each other for what one must assume to be at least a couple years and their level of teamwork, such a thing would be no surprise. For example, after Whisker and Paula are introduced, she's visibly offended that she wasn't introduced first. Also, they are almost always seen together, even when the situation doesn't call for it. For example, when seen at the Island Open cafe, Elroy and Tori look like (and imply that) they're on a date.
