Krailoni is one of John Silver's gang of intergalactic pirates recruited to serve aboard the spaceship RLS Legacy in her expedition to find the legendary treasure of Captain Flint. As the only female member of the pirate crew, she is a small gray alien creature whose body consists solely of a head and a pair of skinny arms terminating on four-fingered hands. She participated in the mutiny along with the other pirates which successfully took control of the ship and found the treasure chamber in the planet, but was later arrested along with Hedley, Torrance, Onus, and Grewnge and presumably brought to trial.
- She is voiced by Mona Marshall.
