Prince was left behind, along with his brother, in the swamp area of Kawanii. At their birth, the two brother's lost their sister, stolen from them by their father. Their mother later informed them that he had taken her to become the heir to his swamp kingdom.
Not long after they reached young adults, their mother no longer able to face them, abandoned them to fend for themselves. The brothers grew close, caring for one another and came to a mutual agreement. They needed a swamp kingdom of their own.
The Green Prince is very protective of his brother, and very jealous of anyone who steals away his attention.
