flame princess

She's the evil, but passionate in other's eyes, princess of the Fire Kingdom. Her evil father, the Flame King, locked her in a lantern so she wouldn't take his reign. She managed to escape with permission of her father to be with "Prince Finn". Finn, not really a prince, rejected her, but later in the series goes out with her. She has recently broken up with Finn and rules the Fire kingdom with a code of honor of "honesty" because she overtook her father and gave him a taste of his own medicine. Flame Princess is a newly created Adventure Time character that kicks butt!

"Woah! Did you see Flame Princess burn that whole forest to the ground?"
"What a butt kicker."
