Jake Smith is the main protagonist of the game, Five Nights at Treasure Island, and is the sole character who is controlled by the player. Jake monitors Treasure Island to collect data for a research team by the name of SSA, of which he is an intern. Jake's full name was revealed in one of Greg's e-mails, where he mentions an intern named "Jake Smith".
- During development of the Remastered Demo, Jake was meant to be replaced by a woman named Dohna. This idea was scrapped because the new
remastered phone call had already been created, and already stated the player's name as Jake.
