Octocommanders look extremely similar to an Octosniper, but they wear a beret and a pair of aviators. They also have fat, purple lips. They are stationed on a platform with a propeller on the back, and the platform can rotate 360 degrees. Their Splatling gun has 6 barrels and Octarian designs on the large cylindrical part. Like their sniper comrades, they have small, stubby legs.
Octocommanders, like Octosnipers, are stationary, but instead of a Splat Charger, Octocommanders use a Heavy Splatling that initially fires a few shots but rapidly increases its fire rate as it shoots. The minigun has a very high rate of fire when it is shooting at full speed, but the Octocommanders take a break each time they finish firing it to catch their breath, giving the player a chance to safely Splat them.
Tips
Wait until the Octocommander is catching his breath, then use that time to strike.
Hide behind a box or a barrier while the Octocommander is firing, making sure not to get caught in the splash.
Trivia
One can stand in a "box of safety", which is the area directly near the Octocommander. The range of the Splatling does not reach past this box, allowing one to get a good look at the aesthetics of the enemy. This also goes for the Octosniper.
