Depending on the player’s selection of gender, skin tone, eye colour, haircut, and ink colour, Agent 4 can have a number of looks. They can select armour to wear in addition to donning the updated Hero Suit.
By default, they utilize the Hero Shot, but Sheldon later grants them the ability to employ a range of additional Hero weapons.
Agent 4 serves as both the player’s avatar in multiplayer modes of Splatoon 2 and the game’s main Inkling protagonist in Hero Mode. Depending on the player’s preference for customization, they can be either male or female, and their hair and eye colour may differ.
Is Agent 4 a boy or a girl?
Since Agent 4 didn’t have a designated gender, it may be of any gender. However, since there are no photographs of a male Agent 4 and no promotional imagery exists, it can be assumed that Agent 4’s canonical gender and appearance are those of a female Inkling with short tentacles.
