The Mask makes you what you want to be, with super powers, all the abilities, and the indestructible nature of cartoons. Luz Noceda would be a powerful witch, she would be inspired a bit by Azura, and she would say funny lines of dialogue while she fights. In her relationship with Amity, she would be her knight in shining armor, charming and brave, until Amity gave her affection, like a kiss, then she would surely end up transforming into a blushing rabbit. Luz flirting with Amity would try to look cool, I imagine her leaning in a locker waiting for Amity while enjoying a lollipop, when Amity arrives, she would take out the lollipop and give it to Amity, and start reciting gothic poetry: comparing the beauty of his girl with the twilight, or the beautiful and deep soul of his girlfriend with the abyss from which she cannot escape and does not want to, something like that.
