Main weapon

"Your go-to weapon can be short-range, long-range, or just plain messy (like the Splat Roller). Each has its own benefits and weaknesses, so there's something for every play style!"

- Splatoon's official website

The main weapon is the primary type of weapon players use in Splatoon and Splatoon 2. Each main weapon has its own set of sub weapons and special weapons.
