There are plenty of great Adventure Time fan theories, but few are more titillating than the supposed lesbian relationship between Princess Bonnibel Bubblegum and Marceline Abadeer the Vampire Queen. They could very easily join the list of gay cartoon stars, according to some fans, and it wouldn't be much of a surprise if they did.
Princess Bubblegum and Marceline's relationship, also referred to as Bubbline, has a lot of evidence suggesting that is so much more than a mere platonic bond. And while there is no shortage of Adventure Time LGBTQ subtext, there are times when it seems downright obvious that the two are gay. It would be more than refreshing if they were able to acknowledge their love unequivocally, once and for all.
