Old Rusty is an old tramp steamer. He makes only a brief appearance in Warrior, anchored out in the estuary, claiming to have been anchored there for two years. He seems to be kind and joked with Warrior, saying it would be boring without him.
He makes two appearances in Salty's Lighthouse, first getting bumped by Warrior and telling him to watch where he's going, and then in a flashback where Top Hat, Warrior, and Otis were reminiscing also getting bumped.
- It is currently unknown where his model is. The only part that is left of him is his face mask.
- Old Rusty is one of the few characters that only has one face mask, the other being Sea Rogue's Uncle, Frank and Eddie, Burke and Blair and Johnny Cuba.
- His model was a combination of Nantucket's hull with Johnny Cuba's superstructure.
