Princess Bonnibel Bubblegum (voiced by Hynden Walch), also known as Bonnie, PB, or P-bubs, is one of the main characters of the Cartoon Network show Adventure Time (2010-2018). She is a very kind and compassionate character with a strong sense of justice, though she has a dark side when provoked.
She is a "Gum Golem" made up of human and candy DNA and rules over the Candy Kingdom. She is friends with the other two main characters, Finn the human, and Jake the dog. She is very protective of her Candy People but is stressed by the burden of ruling a kingdom. At the end of the sixth season, she loses her post as ruler after an election.
Early in the series, she showed to be jealous of Finn when he was becoming closer to the Flame Princess. However, Princess Bubblegum has a strong connection with Marceline the Vampire Queen, often calling her her "best friend". At first hostile towards each other, they develop a strong connection by the third season, and by the last episode, they share a kiss after Marcelene saves her from GOLB.
