After visual development for the character Billy Bones, Harald Siepermann continued with one of the main characters from Treasure Planet, Long John Silver.

Harald Siepermann found Silver quite a complicated character to crack. He worked about 2 months on the character to find the right direction, “Silver, being a pirate, disguised as an innkeeper, half alien, half pirate, was a bit too much to design in one go, something was always right, other things were always wrong, so I decided to design one thing at a time.
