This is a pretty specific question I realize! I was looking at the latest League of Legends character and also Lost Ark’s artist class and I realized I really like the aesthetic of a character that uses a paintbrush as a weapon - paint-related abilities are a bonus!
Kirby has the Paint ability in Super Star and SS Ultra, which got replaced by Artist in Star Allies. You can also play as Adeleine (and Ribbon) if you’re player 2 and choose her as a Dream Friend, or doing the Guest Star ??? Star Allies Go! mode (which also lets you play as Vividria, who has a paintbrush for hair).
There’s Okami and Okamiden, but the latter is gonna require emulation since it never got rereleased.
