Maxine paints the front of her house purple one day for no reason. And then wears a yellow dress because it goes so well with the freshly painted purple house. She always asks her neighbors if she can paint there house purple, even the king at one point, because she loves painting and still has leftover paint.
Just for the hell of it, Maxine asks the Big Bad about his favorite color.
Justified: Maxine has some kind of mental disorder or disability that prevents her from having the awareness or self-control necessary to control her impulses.
Maxine is of a chaoticmoralalignment as well as a very focused, intelligent, rational, and unimpulsive woman who makes clever schemes in the name of intellectual pursuits and rebels because she spent so much time deconstructing and analyzing rules that she sees right through them. So she, not only is she smart, but rebellious because of it. As opposed to a Chaotic Stupid character, who is portrayed as just plain old chaotic because they're stupid.
Mad Maxine can be impulsive and wacky, but is capable of controlling her impulses when the situation calls for it.
Exploited: Mad Maxine's enemy chucks a fish at her, hoping she'll be distracted and run off to dance with it or something.
Defied: Mad Maxine is ashamed of her behavior in the past, and does the best she can to control her impulses for the good of the party she's with now so she won't be "that" person again.
Discussed: Mad Maxine's behavior is going to get her in trouble. Not to mention she's annoying!
"Mad Maxine is crazy!"
"What would you expect from 'Mad' Maxine."
Mad Maxine acts this way because she wants attention. Any attention. She's also bored and wants to shake things up a little.
Mad Maxine's antics distract and annoy her teammates while having little to no effect on their enemies. She also can't be depended on to fulfill her role in The Plan or even in battle. As a result, the team's first battle with the Big Baddoesn't go so well.
Reconstructed: Maxine learns when it's OK to do crazy things, and when it's not. She might still exhibit impulsive behavior, but will stop if asked or reminded.
Plotted A Good Waste: The story starts with a number of heroic characters on a journey. There's a Knight in Shining Armor, a Paladin, and a Beastmaster who are all strong and majestic, striding through a forest with the sun on their faces and the wind in their hair... and a Child Mage who keeps summoning a bunch of stupid fish, turning things purple, and summoning slime to fall on her teammates. Then it turns out we're seeing a dramatization of a Tabletop RPG, and she's the Annoying Younger Sibling who insisted on joining the game.
Played For Laughs: The creators of the show wants Maxine to be Plucky Comic Relief, but really overdoes it. But it actually works, and everyone loves Maxine.
Played For Drama:
Maxine has to learn to control herself. It's easier said than done, but she does her best.
