Hocker is an elderly man with a moderately wrinkled face, short purple hair and beard. He wore a light red shirt, white pants, normal shoes, and a red wool cap.
Forty years before the start of the series, Hocker was one of the many people from an old town destroyed by pirates who came to Organ Islands to build Orange Town. Hocker befriended the mayor Boodle. Hocker opened a pet shop, and had a dog named Chouchou. Eventually, Hocker suffered from an unknown illness, and went to see a doctor, leaving Chouchou to take care of his pet shop. Hockera died from the illness and never returned to Chouchou or his shop.
