Tyrian Callows is an antagonist in Project Yellow. He is an associate of Salem and part of her inner circle.

Tyrian is a psychotic incarnate, and someone who wants to see the world burn. Tyrian appears to be a highly unstable and maladjusted individual. He frequently bursts into fits of uncontrollable, maniacal laughter and relishes in gruesome thoughts. He finds amusement in taunting his opponents while he fights,indicating a level of bloodlust. When he appears to have the upper hand in a fight he becomes overconfident and careless, letting himself take hits as long as he can continue to press the advantage. He also has a flair for the dramatic, wildly posturing and gesturing with deliberate dramatic pauses as if he were giving a stage performance. Another one of his eccentricities is sitting in a crouching position in his chair.
