So, we've got a new visual glitch huh? Nice. I'm here to speculate and talk about who I think Daisy could be based on.
Before I start though, I am 100% a firm believer these glitches do mean something, because every character that has had glitches fit so well for characters we have gotten. Mii Swordfighter, Duck Hunt, Simon\Richter, and Bayonetta are painfully obvious bases for Hero, Banjo, Byleth and Min Min. As such, I do believe these glitches are something we should be on the look out for in the near future.
Anyways, if I had to make a guess on who Daisy could be based on, I am down to two options. The first character that could be based on Daisy could be Arle, since she looks very similarly to Daisy and Daisy's glitched out skirt easily resembles Arle's skirt. Daisy also has a glitch where she turns a different color, and in Puyo Puyo, all of the Puyo are different colors. Now, I have never played a Puyo Puyo game so this is just mindless speculation here, but maybe Arle changes a different color depending on a certain action with the Puyo? Like I said, I never played Puyo Puyo so I'm not sure if that could work.
The second character that I think could be based on Daisy is Reimu from Touhou. She just looks like she could be an easy base for Daisy since her skirt easily resembles Daisy's. She could also fall in line with the Daisy-crown glitch since her bow-tie could be something she could take off in like a taunt. Either way, she is another possibility too.
And to keep things Geno-related, I think the Daisy glitch could unironically work for Geno, since as shown in
papagenos
's video, Geno has an animation where he takes off his hat whenever he uses honey syrup. Maybe this could be used as one of Geno's taunts or idle animations. Either way, I do think we should keep an eye out on this glitch, as well as Ness's eye glitch as well.
