Mario Tennis Aces

Mario Tennis Aces is a sports game in the Mario Tennis series for Nintendo Switch, initially released on June 22, 2018. It is the eighth installment in the series and is Princess Daisy's sixth appearance in the entirety of the Mario Tennis series so far.

Daisy was originally leaked (along with Yoshi, Rosalina, and Bowser) in screenshots posted before the March 2018 Nintendo Direct. She was officially confirmed in said Direct.

Design and Stats
Compared to Mario Tennis: Ultra Smash, Daisy hasn't changed that much physically. She now wears an orange and yellow wristband on her right arm and also wears a modified version of her former sneakers. Daisy is an All Around type character, just like in Mario Tennis: Ultra Smash and the tennis mode of Mario Sports Superstars meaning like Mario and Luigi she has all balanced statistics

Adventure Mode
Princess Daisy is a supporting character in the game's Adventure Mode. In the opening cutscene, Daisy is seen watching Wario and Waluigi offer Mario the legendary racket Lucien with a worried expression. When Lucien possesses Luigi, a cyclone begins ensues. Daisy is the first to run for cover.

Once the storm concludes, Daisy talks with Mario, Toad and Peach about what happened. Daisy notes that Wario and Waluigi were acting very strange and later realizes that Toad isn't telling the group everything he knows and demands him to reveal the information.

Daisy wants to help Mario find Luigi but Toad convinces her to stay since the job wasn't suited for two diplomats and just in case Luigi, Wario and Waluigi decide to attack the stadium. Later on in the game, Mario and Toad return to the stadium and reunite with the princesses. The princesses then have a match against the possessed Wario and Waluigi.

When Bowser takes off with the racket, Daisy expresses anger towards him. Once Bowser (who fused with Lucien to make Bowcien) is defeated, Wario and Waluigi complain about no longer being the best players, Daisy scolds the duo.

In the story, Daisy is portrayed as a more pragmatic and fearful character as opposed to her more cheerful and reckless personality seen more frequently. She is still quite fiery, rushing Mario and Toad to inform her on the situation once the two return to the stadium.

Similarly to their real life personalities, Daisy's poses and stances are much more exaggerated and coquettish than Princess Peach's more modest and elegant poses.See the Mario Tennis: Gallery.
