Princess Bubblegum

Princess Bubblegum is the tritagonist and one of the love interest of Finn in Adventure Time. She is a hero in her own right: in the episode "Lady & Peebles," she personally rescues Finn the Human and Jake the Dog (after both went missing for three weeks), and defeats the antagonist Ricardio the Heart Guy. She frequently gets kidnapped by the Ice King (to be rescued by Finn and Jake) and is very similar to Princess Peach, because they are both princesses and they both get kidnapped. They both also have pink as their signature color.

She is voiced by Hynden Walch (who also voiced Penny Sanchez from ChalkZone, and Starfire from Teen Titans), and Isabella Acres as her younger self in two episodes (during which, while temporarily Finn's age, she reciprocates his romantic feelings). In the Adventure Time episode "Incendium," she reverts to her usual dismissal of Finn's efforts, causing him to begin a relationship with the volatile Flame Princess.
