You think his friends just called him Yellow Eyes? He had a name.
This article is about a canonical individual whose real name is unknown, and is known only by a conjectural title, nickname or alias.

This unnamed Leviathan took on the form of Sam Winchester, after he got a sample of Sam's DNA from a motel bathroom. He and Leviathan Dean posed as the Winchesters and shot up locations across the United States to put them on the Most Wanted List.


Leviathan Sam, along with Leviathan Dean, committed several murders in Jericho, California; Black Water Ridge, Colorado; Lake Manitoc, Wisconsin; St. Louis, Missouri; and Ankeny, Iowa — all places where the real Winchester brothers had already worked cases (during the time of Season 1). Their plan was to frame Dean and Sam so that, once they were arrested, they would have been easy to locate and kill. He traveled with Leviathan Dean in a '67 Impala, almost identical to the one that Dean Winchester drives except for its custom rims and Illinois license plate.

Leviathan Sam as a sheriff officer

He disliked having to impersonate the younger Winchester, complaining about Sam's mental issues (resulting from his time in Hell with Lucifer) and about the food he eats, saying it was like eating "self-righteousness." He even tried to trade disguises with the other Leviathan, but to no avail. During a conversation with Leviathan Dean he mentioned he had a brother with many issues like Sam and how he ate him.

Dean later confronts and decapitates him with the a fire axe after Sheriff Osborne splashes Leviathan Sam with borax in Ankeny, Iowa. Dean and Sam then take his and Leviathan Dean's heads to dispose of separate from their bodies, which they leave with the sheriff. Their bodies are eventually recovered by the Leviathan posing as Agent Valente.
