Tommy is an unseen character that is mentioned in Hello End. He was the former bassist of Withered who was convinced to leave the band by Zack Cobra. He is mentioned by Chloe Witheral in the opening cutscene of the mission Waning Sanity. If the player character is male, Chloe drunkenly shouts "Are you Tommy!?" at the player character, mistaking them for him.
Not much is known about Tommy, except that he was the bassist of Withered. He never saw the moments between the Witheral siblings, and it was only by Zack Cobra's persuasion that he actually left. His state is unknown, as he never appears in the game.
