Bepo was born on Zou.
At age eight, Bepo wanted to chase after his older brother, Zepo, and climbed down Zunesha's leg to get a better view of the sea, but he got swept away.
He later boarded a ship heading for the North Blue, and a year later, he wandered through Swallow Island.
On that island, he was bullied by two boys named Shachi and Penguin, but another boy named Trafalgar Law came and knocked out Shachi and Penguin with his Devil Fruit powers
