Hero Suit

The Hero Suit is the costume worn by the Inkling in the story mode of Splatoon. It is said to help "protect against the Octarians."

The suit is made up of 3 pieces of gear for the head, chest, and feet. Based on the multiplayer stats, the complete suit boosts running, swimming and launching speeds.

Upon completing Hero Mode, a replica suit is unlocked to wear in multiplayer along with the Octoling armor.

The stages in story mode contain Power Eggs, which are used to power up the gear.
