Bosko lived in a really abusive household in the Kingdom of Raveryn as a kid. Raveryn was a kingdom where all raccoons resided. Bosko's father would literally trade him for a 6 pack of beer if he could, and his mom couldn't give 2 shits about his diet or health since she was too busy smoking up a storm in the house. They treated him badly and always made him at fault for everything.
When he was 12 he was so tired of the way he had to live that he ran away to Timberglen. With no home and family, he had to learn to live on the streets by stealing food and pickpocketing for money. He would spend many nights sleeping on an empty stomach and had to endure sickness from sleeping out in the rain. About 2 years later he would meet Drayven, who now also homeless, had to learn to adapt and learn from Bosko if he wished to survive the cruel streets of Timberglen. They were taken in by Acher's Gang - The Asosa Raiders- a small pack of ruffians who worked together to survive by stealing food and money.
As they got older Bosko and Drayven didn't see eye to eye with the gang's leader and resulted in them abandoning the group. They lived alone together as wanted criminals in Timberglen until Emerald Kamala befriended them and asked them to leave their old ways to join her fight against Talon and his demons. Along the way, she met Dawn DeLaney who becomes his love interest.
In the future Bosko is invited back to the Kingdom he lived in as a child. Although reluctant to go, he is convinced by Dawn and the other friends to go. When he gets to the kingdom it is revealed that he is actually next in line for the throne and needs his people to guide him since his REAL parents have recently deceased. He denied his place for a while until he was convinced by the royal adviser to help. He promises to only help during the incoming attack and that he will surrender the throne after the war has passed.
