The Octostomp was an Octoweapon created during the Great Turf War by the Octarians. When it seemed that victory had smiled upon the Octarian army, a plug was pulled and caused the Octostomp and the rest of the Octarian mechs to shut down. Nearly 100 years later, the Octostomp was brought back to life by the power of a Zapfish in order to attack once again.
The Octostomp is a robotic Octarian in the shape of a large cube with several layers on its Octotrooper-like face covered in purple ink. It has nine metal panels on most of the sides other than the front and bottom and has a hole on its back where a tentacle can grab Zapfish. It also has two Octarian feet that somehow are strong enough to make it jump. In the second game, the Octostomp is given an ink-proof jacket, that appears to be made of thermal fabric, along with a rubber belt.
In Splatoon, the Octostomp is the first boss Agent 3 encounters. It appears in the mission The Mighty Octostomp!, where they have to dodge its attacks (which are it slamming its face into the ground) and climb up its body to splat the tentacle. Each time, it will remove several panels from its body, and in its third phase the panels will begin moving, making it harder to climb. Once Agent 3 has splatted the tentacle a third time, the Octostomp will be defeated and explodes.
In Splatoon 2, the Octostomp comes back as the third boss in the fittingly named mission The Octostomp Returns, where this time it comes with a few tricks up its sleeve. The first phase plays out normally, where Agent 4 must dodge it then climb to its back to splat the tentacle; however, it does have a new attack in which it rushes forward before smashing its face down. In the next phase, it gains an uninkable coat with a belt around it and is called the "Neo Octostomp". Agent 4 must destroy the buckle to remove the coat in order to climb it. Additionally, it gains access to a Splatling attack. In phase 3, it once again uses the coat, but now has two extra faces, making its attacks more difficult to avoid. After the third tentacle has been splatted it explodes, just like last time.
The Octostomp appears for a third time in the Octo Expansion, where it has been Sanitized and renamed "Octostomp Redux". It now resides in Drop the Bass Station where it can be battled. The boss battle is very similar to the one in Octo Canyon, with its ink-proof coat, but there are differences. It has its coat in all three phases rather than only the last two; additionally, in its second phase, it has two extra belt buckles on its side, forcing Agent 8 to destroy all three. In the final phase, it has three belt buckles once again, but this time it is due to its extra faces each having their own belt buckles. Additionally, it gains the ability to blow bubbles from its mouth(s), which it will usually attempt to pop with its Splatling, resulting in a chain explosion. Once its coat has been removed, it will release bubbles from both of its sides every time it smashes its face onto the ground, which makes it slightly harder to climb. Once Agent 8 has splatted the tentacle enough times, Octostomp Redux will be defeated and will, like always, explode.
There is an Octotrooper seated at a splatling on top of the Octostomp. The Octotrooper does not share the appearance or behavior of the other enemy type that uses a splatling, the Octocommander. The Octotrooper and splatling are visible in phases 2 and 3 of the Neo Octostomp and the Octostomp Redux battles. Unlike the Octocommander's splatling, this splatling does not appear to have a windup time and the fire rate does not become faster. In the Octostomp Redux battle, if there are any bubbles left over, the Octarian splatling will attempt to pop them, causing a chain explosion.
- The Octostomp is the only boss to be battled in all of the single-player campaigns.
- Octostamps, Octostamp DXs, and Octoseekers all appear to be based on the Octostomp.
- It is so far unknown how the Kamabo Corporation managed to copy and sanitize the Octostomp, along with the rest of the bosses.
- It is also implied that the Octostomp remembers its last battle when it says "Back like I never left", despite being Sanitized.
