Aerospray MG

The Aerospray MG is a main weapon in Splatoon and Splatoon 2.

The Aerospray MG has an extremely high rate of fire, but each shot is weak individually. It takes five hits to splat an opponent. It shoots with high spread, allowing its users to quickly cover turf and to hit opponents without perfectly aiming at them.

Splatoon
The Aerospray MG comes in a set with the Seekers and the Inkzooka. It can only be purchased after defeating The Rampaging Octowhirl Boss Battle and obtaining its Sunken Scroll. It was created by Sheldon from his grandfather's blueprints.

Trivia

 * The Aerospray MG appears to be designed after an aerograph, a type of airbrush.
 * The Aerospray MG, along with its alternates, the Aerospray RG and Aerospray PG, and the Inkbrush, Inkbrush Nouveau, and Permanent Inkbrush, are the only weapons that require 5 hits in order to splat an opponent.
 * The "MG" in this weapon's name likely stands for "Master Grade", referencing Bandai's line of 1:100 scale model kits for the anime Mobile Suit Gundam. This is likely because it is common for model kits to be painted with an airbrush and Gundam models are extremely popular in Japan.
 * In Splatoon 2, the Aerospray MG was the only weapon to be the only weapon unlocked at its level for more than a year.
