While Princess Bubblegum is typically kind, good-hearted and well-mannered, she can be very temperamental and has shown a malicious aspect of her personality whenever she is crossed. Even with her kind disposition, her moral code is not as strict as yours and there are also hints of a darker aspect of her personality, and her humor is also morbid and inappropriate at times. Bubblegum also adores the people of her kingdom and puts their safety above all else, even if it exhausts herself.
