Tyler is a recurring character in Season 2 of Big Mouth. After Ricky retired from being a Hormone Monster, Tyler takes his place as a Hormone Monster-In-Training.


Tyler represents Maurice in many ways, the most notable being his hair. Like Maurice, Tyler does not don clothes and has hair covering half of his body. Unlike most Hormone Monsters, he starts his role in the show without his horn, which is a symbol of succeeding as a Hormone Monster.


Tyler is a young Hormone Monster, taking Nick as his first adolescent. He makes many mistakes and is conventionally childish, while also having a perverted side. He's first found by Nick in his closet, and happily introduces himself. Throughout the season, Tyler pressures Nick into making immature mistakes, such as telling his friends that he got to touch Gina's breasts, an action which results in a lot of drama. Tyler's ultimate mistake is revealed to be following the orders of the Shame Wizard, under the pretense of a wanting to make Nick a better person. After that, Nick decides that he's fed up with Tyler's nonsense, and the latter is fired for his secret alliance. On his way out of the human world, Tyler leaves a portal to the Hormone World open in Nick's closet. When Nick enters it, he discovers Tyler's new position as assistant to Gavin, an uptight Hormone Monster that usually abuses Tyler. After Nick escapes the Hormone Land, Connie becomes Nick's new Hormone Monster, a reveal that ends the final episode of Season 2.
