The World of Skies of Arcadia is a location that appears in the Worlds Unite crossover published by Archie Comics. It is an alternate Zone connected to the Multiverses hosting Sonic's World and Mega Man's World. This world was among the many to come under threat from Sigma, forcing its inhabitants to rise up alongside the heroes of the Unified Army.
When Sigma sends several Mavericks to different worlds, Tidal Makkoeen attempted to set an Unity Engine on Crescent Isle, but the Blue Rogues defended the area from him, being finished by Vyse's Cutlass Fury. After the battle, Knuckles the Echidna and Quake Woman appeared and convinced the Blue Rogues to join the battle against Sigma, with the Unified Army using the Delphinus as a temporary base after the Sky Patrol's destruction.
- Blue Rogues: A group of air pirates that only attack armed vessels larger than their own ships, specially those from the Valuan Armada.
- Vyse: The teenage leader of the Blue Rogues and swashbuckler who fights with twin cutlasses
- Aika: Vyse's close friend since childhood. She is energetic and has an obsession for treasures. Aika fights with a large boomerang.
- Fina: One of the few Silvites left, a demure and intelligent woman with an iron will that develops a strong bond with Vyse and Aika.
- Cupil: Fina's pet. A silver ball-like creature that can morph into various shapes and fights for her.
- Drachma: A bitter old man that lost his family and had his right arm torn off by the arcwhale Rhaknam. His arm was replaced by a large mechanical prosthetic that he uses in combat.
- Enrique: The charismatic prince of Valua. He has a strong moral sense, which puts him at odds with most members of the Valuan nobility. This causes him to join Vyse, and he lets the Blue Rogues take the Delphinus.
- Gilder: The captain of the airship Claudia. He is a fun-loving, laidback womanizer that fights with guns.
- Crescent Isle: A crescent-shaped landmass that floats in the skies of Arcadia (like all landmasses in that world), similar to Angel Island.
- Delphinus: The main vessel and home of the Blue Rogues, and one of the most powerful airships in their world.
- This is the reality where the Skies of Arcadia video game published by Sega takes place.
- Drachma's character and backstory are noted for being based on Captain Ahab from Moby-Dick, whereas Aika has been noted for being similar to Sticks the Badger.
