10 HARDEST Splatoon Bosses

10 Hardest Splatoon Bosses

Welcome to MojoPlays, and today we’re looking at the toughest boss fights across the “Splatoon” series!

Mr. Grizz

“Splatoon 3” (2022)

Previously just a mysterious voice on a radio, Mr. Grizz closes out the story of “Splatoon 3.” And completely befitting of a final boss that’s a gigantic ultra-powered grizzly bear, he’s pretty tough. Mr. Grizz comes in three phases. During the first, his attacks cover a lot of your area in ink, so you have to keep up a steady spread of your own and carve a path towards him, while dealing with enemies. After that, Mr. Grizz’s phases come with time limits, which naturally adds a little more stress as you’re trying to fend off enemies and Grizz at the same time.

Stinger

“Splatoon 2” (2017)

Salmon Run has more than a handful of annoying bosses that, if not taken care of immediately, will only cause your team pain. Stacked on top of some cooking pots, this little devil can snipe an Inkling from the other side of the map. And it isn’t just a single blast; it’s a stream of ink that eats into you in a matter of moments. Of course, they also always attack from far away. It can be especially annoying as they start to appear in larger numbers, splitting your team’s attention among the other enemies. Not only is that a lot of damage to deal with, but they can cover a good amount of your ground depending on the map.

Octo Shower Supreme

“Splatoon 2: Octo Expansion” (2018)

The “Octo Expansion” takes a couple of the bosses from the base game, and gives them a nice challenge upgrade. You can only fight the boss with the Inkjet, and the gun that comes with it has a slow fire rate. And while you’re flying around trying to hit the boss, it frequently fires pairs of homing missiles at you. The second phase is a chore, as it feels like there’s a constant barrage of damage, whether from the Octo Shower’s own, much faster-shooting weapon, or when it rains ink down while dashing across the arena, which is nasty to get caught by.

Parallel Canon

“Splatoon 3: Side Order” (2024)

“Side Order” introduced some roguelike mechanics, meaning that every run through the Spire of Order is a little different. But Parallel Canon is usually a drag to run into. Fought on the 10th or 20th floor, though with more power and numbers on the latter, they seek to overwhelm in large numbers while cycling through different tactics as they go. What can make them intimidating more often than not, are the Chips in your palette. The more you have, the more predetermined ones they’ll have. With the amount of damage they can spread through each wave, they’re certainly good at keeping you on your toes.

Flyfish

“Splatoon 2” (2017)

Perhaps even more annoying than the Stinger is the Flyfish, due to its tenacity when it comes to staying alive. A Smallfry with two homing missile launchers mounted on its back, you have to use an explosive weapon to destroy them, as the Smallfry itself can’t be damaged. And if you don’t take care of it as quickly as possible, you’ll regret it. They can target two players at once, and getting by one of the Flyfish’s missiles means instant death. They’re particularly irritating, since it can be hard to destroy their launchers in the heat of the moment. These Salmon Run bosses may be small, but they can cause a lot of mayhem.

Revenge of the Octo Samurai

“Splatoon 2: Octo Expansion” (2018)

Another boss made much harder by the expansion, Revenge of the Octo Samurai, much like the Octo Shower Supreme, becomes much more difficult because of the weapon you’re forced to use. You’re placed inside a Baller, which has you roll around and deal damage by charging up an explosion. You have to time those explosions right, because the Octo Samurai is trying to knock you off the arena with a giant paintroller, and he hits pretty hard. Unless you’re being knocked from the exact opposite side, there’s a good chance you’re going over. And of course, the boss only gets more aggressive as he gets closer to defeat.

Megalodontia

“Splatoon 3” (2022)

When the Salmon Run mode returned with Next Wave in the third game, Nintendo gave us some much more boss-sized bosses to contend with. Three gigantic King Salmonids, all of which are naturally intimidating to go up against for the first time. But of the three, it’s Megalodontia who poses the biggest threat. Part of it is because of the boss’ sheer size, which comes with a larger health pool than the other two. Although this scales depending on the hazard level of the room, it’s usually an issue considering you’re also given a time limit during these fights. Megalodontia pops up at different points around the arena to deal major damage to one player. The weak spot on its back is obvious, but it won’t always be in your line of sight, especially with all the other regular enemies and smaller bosses vying for your attention.

Overlorder

“Splatoon 3: Side Order” (2024)

As expected, since Overlorder stands between players and the end of their climb up the Spire of Order, it’s the hardest boss fight the DLC has to offer. Phase 1 of 4 is simple enough; you have to destroy Overlorder’s two portals that spawn enemies that home in on you. After that, the boss lets loose. The number of portals increase in Phases 2 and 3, and are harder to hit since they move once they take damage. Meanwhile, Overlorder is trying to wallop you with its tentacles. In Phase 4, you have to get new Chips by destroying portals, as your palette will have been empty.

Triumvirate

“Splatoon 3” (2022)

What’s worse than one King Salmonid? All three of them. The Trumivirate sees Megalodontia, Cohozuna, and Horrorboros join forces. You still have a time limit constantly ticking down, and you still have to worry about other enemies and smaller bosses filling the rest of the space. The one saving grace is the ability to use their attacks against them. The bosses can each destroy enemies that are caught in the crossfire while going for you. And one attack from a King Salmonid can still hurt another. Even still, that’s obviously a lot of spinning plates to balance, and it is a lot of nasty ink that can quickly splat you.

Inner Agent 3

“Splatoon 2: Octo Expansion” (2018)

The bosses in the Octo Expansion are tough. But the secret boss puts them all to shame. You have to prove yourself worthy of reaching the fight first, collecting all eighty mem cakes throughout the DLC. That takes a while, but the fight against Inner Agent 3 will feel even longer. It comes in five phases, with different weapons and tactics used for each one. Simply put, they’re just cracked. Their speed and maneuverability is on another level, easily able to bob and weave throughout attacks. And their high accuracy with each weapon is sure to make you sweat. High offense and defense makes Inner Agent 3 one of the hardest secret bosses in recent Nintendo memory.
