Funny thing: Splatoon Canon is incorrect, priar to what really happened. I'm not shouting, I thought I'd rather address it. Despite Agent 3 "canonically" being feminine, he isn't. The only true thing of displaying Agent 3 as "Female" would be the rumors around Inkopolis Civilians and the Splatoon Agency. The things that are true is his hair and skin color-his hair/ink being green and him being white-, but his eyes are brown, and his most seen hairstyle is the one where it has 3 tentacles pulled back. The truth is uncovered when Agent 8 faces him near the end of the Octoling Revolution. His name is questionably 'Remix "Jazz" Downbeat' (Fun Fact: The Hero Shot wielded by Agent 3 is actually the "Call of Duty Black Ops 2" DLC Weapon, the Peacekeeper, which is a fictional weapon based on the United Nation's AAC Honey Badger, which is a Submachine Gun with the Range and Accuracy of an Assault Rifle).
