Vocal Range: Any

Voice: Open to your interpretation! He's definitely an easily excitable fast-talker who tends to ramble on though.

Important:  Sheldon's role in Splatoon 2's story mode is to gather data on the weapon's Agent 4 uses throughout the hero campaign. His key dialogue points are during the radio transmission sections with Marie and at the final stage of the last boss.

Character Profile: Sheldon is a genuine military fanatic from a well-respected family who is fascinated with his weapons. He has developed nearsightedness due to staying up late every night tinkering with weapons and small parts, causing him to be rejected from the military for his extremely poor eyesight. Undaunted, he decided to start a business selling weapons out of his own home, and Booyah Base was eventually built on the same land upon which that home stood.
