Protagonist of [i][[splatoon_3|Splatoon3]][/i]'s Hero Mode.

Do not confuse with [i][[agent_3_(splatoon)]][/i].

In this work, the former Agent 3 has succeeded  [[Cap'n Cuttlefish]]  as Captain. Therefore, the new agent inherits the callsign of the previous "Agent 3".

Due to New Agent 3 being the player character, they can be depicted as either gender, though they are often drawn as a girl with [[single_braid|single braid]] [[yellow_hair|yellow]] [[tentacle hair]] thanks to promotional materials surrounding Hero Mode. Regardless, Agent 3 always wears a "hero suit" consisting of a yellow jacket and [[earphones]].
However, the suit is damaged at the beginning of the story, and the story proceeds with a  black [[crop_top|crop top]] top and black [[sweatpants]].
Also, at the beginning of the game and during editing, he wears asymmetrical shirts, sneakers, sunglasses, and cloaks. I often have a [[tri-stringer_(splatoon)|tri-stringer]] in the package and PV.
