Bubby is the daughter of the Spirit of the Wall, the ghost of the Wall of Flesh who governs the underworld whenever the Wall of Flesh is dormant. This position makes Bubby the Princess of the Underworld, and she lives up to her royal rank- powerful and dark. She is a Cambion- half demon, half human. Her mother died to a curse, giving Bubby the unique power to curse anything whithin physical reach. Her power is limited though- it can only be used when she is in a "demon" state, and it cannot even be detected when she is in a human disguise. When she was born, she was sleeping soundly. The Crimson was with her, granting her Crimson-related strengths and weaknesses. It also granted her an unusual eye color- red. When she woke up, she knew of her mother's curse, and ultimately death. She was raised to be like pure demons, fighting like them and living life the same. Her father's attempts to make her indifferent to purity were in vain, because she summoned two long assassin's blades instead of demon sickles, and assassin blades were hard to throw. She also didn't have demon's horns, but rather had human hair. This was not the same for her claws and wings, however. Because she could not be trained as a Mage, she was trained to be a Melee warrior instead. This lead her to being an assassin, eliminating powerful enemies in secret during wars and events. There were many wars during her 11-year lifetime, including the last remnants of Chuthulu's reign of terror. These events lead her to be not only the Princess and first royal Cambion, but also the underworld's youngest assassin and most powerful underage warrior. As she grew up, the Crimson overtook a human warrior, and they were driven to destroying the island in which Bubby and few others resided. However, Bubby stopped this by possesing a human warrior, who she had fallen in love with, in order to save him and fight the evil warrior. She won, preserving peace in her war-torn home just in time for her 11th birthday. Despite summoning two swords in roleplay, in game Bubby only uses a Meowmere. She also uses few other weapons.
