Hardest Bosses in the Splatoon Series

The Top Ten
1 Inner Agent 3 (Splatoon 2)
2 Mr. Grizz (Splatoon 3)

(Keep in mind Splatoon 3 is the only Splatoon game I've played all the way through) Mr. Grizz too me the longest out of the Splatoon 3 bosses, at probably around 4 days, I finished the story mode (first playthrough) in 3 weeks. Hard boss, but once you get used to him he's easy.

4 Stinger (Splatoon 3)
5 Flyfish (Splatoon 3)
6 Revenge of Octo Samurai (Splatoon 2 Octo Expansion)
