Turnbuckle was the Zirrelian Helmsman of the RLS Legacy during the Doppler Expedition to Treasure Planet. He took part in Silver's Mutiny, and the latter seemingly fell to his demise during the collapse of Treasure Planet. However, it is later revealed that he survived, alongside other members of the Pirate Crew, led by a new captain.
- Turnbuckles appearance in BaP seems to suggest that the game's storyline takes place in an alternate timeline. One in which Turnbuckle was one of the pirates to be imprisoned aboard the RLS Legacy following Silver's Mutiny.
