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 demon was captured by Ruby and Sam Winchester as a test subject.


In order to train Sam's psychic abilities, Sam and Ruby captured this demon and bound him within a devil's trap in Sam's hideout. There, Sam attempted to exorcise the demon with his abilities, pulling the demon partially out of his vessel. However, Sam was unsuccessful and the demon returned to his vessel before he could be fully exorcised. Sam made a second attempt, pulling the demon a little more out of his vessel but ultimately failing to exorcise him. Sam got a nosebleed from the effort while the demon returned to his vessel and laughed at Sam. Annoyed, Ruby stabbed the demon through the throat with the demon-killing knife, killing him and stated that it was "not funny." Sam then apparently buried the dead vessel somewhere.

Months later, Sam told Dean the story of his encounter with this demon to Dean. Before starting, Sam noted that he was "a bad student" and used this demon as an example of why.
