Daisy is portrayed as a tomboy with an extroverted personality and a tough demeanor. She can be described as spunky, energetic, loud, cheerful, and confident. In the song Save Me With Your Charm, she was shown to speak with a British accent, although in later appearances, when speaking, she uses American slang and has a twang to her voice. She also has a sassy side, often regarded for her wittiness and attitude. Unlike Peach, Daisy is not as proper or poised as she would be based on her appearance and status as royalty; such as standing with her hands on her hips, exhibiting hotheadedness in defeat, and showing off in victory or to get her way. It has been suggested her choice of colors could reflect her personality,[30] with orange being her favorite.[31] She likes to go shopping and dine at fine restaurants, but gladly passes up such enjoyments to train instead.
Daisy is also portrayed as a champion. In Mario & Sonic at the Olympic Winter Games, she seems to be an expert on skating sports; at the point, she was the only one who managed to beat Lakitu's missions. In Mario Strikers Charged, she won the Brick Wall Award for four consecutive years, and five after beating her challenge. In Mario Party 3, she said that she had never lost before, not even to her father.
Daisy has claimed to be clumsy. She fell off stage while receiving her trophy in Mario Tennis, needs help after getting lost in the Remix 10 pipe in Super Mario Run, and admits to being absentminded while waiting for her turn in Fortune Street.
Daisy will use her charms and tough temper to get what she wants. In Mario Party 3, she flirts with the Millennium Star to get the Beauty Stamp, and she swats Bowser into the sky when he gets in her way.
In Super Mario Strikers and Mario Strikers Charged, her personality is heightened. She celebrates scoring by showboating; throwing herself on the ground as she pumps her arms, brushing her shoulders off, and making a sizzling sound as she presses a finger to her backside. She responds to opponents scoring by trying to conceal her injuries, and she crosses her arms and taps her foot disapprovingly at her teammates, who cower in response to her wrath. In Mario Tennis Aces, she largely has the same personality traits as before, although she does show some lack of confidence after witnessing Lucien's possessing Wario, Waluigi, and Luigi, even believing they may not even be able to beat Lucien due to its powers. She also showed some common sense, as she immediately suspected Toad knew more than he let on about Lucien and demanded he tell the truth, and later became disappointed in Wario and Waluigi for even considering getting Lucien again after Mario beat Bowcien, especially after what happened to them earlier.
In Fortune Street, Daisy's personality is more heavily explored with the robust amount of dialogue among characters. She is shown to be impulsive and excitable, eager to take on big challenges and try new things; like scaling the Colossus and riding the flying train at the Observatory. She considers becoming a professional athlete when tasked to pick a new trade-in Alltrades Abbey, and she repeatedly remarks on wanting to take home cute creatures like Yoshi and Slime to have as pets. Daisy is shown to be domineering and direct to others, teasing and bossing Luigi around when his shops are not large enough. She also talks down to enemies like Wario, Waluigi, and Bowser, refusing to congratulate their success and criticizing their shops, believing they would commit foul play. The same game also shows she's not above pitching a fit or forcing others to pay up to allow her to get an expensive item at her request, based on some of her comments. She also implies that she has a bit of a ruthless side, as she makes clear that she's willing to "fight dirty" despite her status as a princess when warning others to not underestimate her. It is also hinted in her bio for Mario Party 3 as well as her comments to Birdo that she is a bit vain regarding her appearance.
Daisy's love for flowers is one of her most notable traits. In addition to having flower accessories/patterns on the majority of her outfits, her presents' room in Mario Party 4 notes Daisy likes to pick up flowers herself. In Fortune Street, Daisy says she would like to be gifted a flower bouquet rather than being gifted a victory. In the story mode of Mario & Sonic at the Olympic Winter Games, Daisy is ecstatic to see the flowers a Chao took care of for her and proceeds to kick off a Kiki who wants to damage them. According to the Super Game Boy Player's Guide, Daisy enjoys working in her castle's rose garden
