Percy Jackson and the Olympians: Legends

Skelly is depicted as a blue-white skeleton with vibrant red eyes, an anatomically upside down nose in the shape of a heart and an expression of excitement. In an interesting departure from typical skeletal appearances, he possesses a few strands of black hair on the top of his head, accompanied by shaggy sideburns and an irregular ridge along his back. Notably, Skelly places a coin with the symbol of the House of Hades in his mouth. This unique combination of features further enhances Skelly's distinct appearance in the game. As Schelemeus, he looks vastly different from his previous appearance. He now sports a white beard, a headband and his chest is adorned with three medals (gold, silver and bronze). Also, he now wears a long red cape that covers a small part of his right arm, a brown skirt held in place by a silver belt with a crescent moon on it and uses a walking stick. He's no longer hunched back, either, instead standing perfectly straight.

Although he is a skeleton, Skelly possesses a vibrant spirit. He is fiercely loyal and courageous, aiding Zagreus in his escapades behind Hades' back. Skelly tends to exhibit extreme behavior, being highly enthusiastic, talkative, and condescending towards those within earshot. Skelly is friendly and helpful by nature, but he has a tendency to quickly develop a sense of familiarity with others, as if he were an expert in the ways of war. Achilles disapproves of Skelly's imprudent advice and questions who Skelly might have been in life to possess such unwavering confidence in death. As "Schelemeus", Skelly takes on an almost over-the-top parody of a Drill Instructor training Melinoë and various other Shades on how to defend themselves against Chronos' forces. Though he acts more serious than in Hades, he nonetheless retains his old joking manner and will occasionally lose his stiff demeanor and respond to Melinoë casually.

Skelly's past is shrouded in mystery. It's implied that he was once a formidable warrior who finally died after surviving numerous legendary battles. Skelly is shrouded in secrecy, claiming to have been hired by someone who seeks to aid the prince's escape, yet he refuses to disclose the identity of his employer. Now styling himself as 'Commander Schelemeus', he now resides in The Crossroads, helping Melinoë with her training.
