Game appearances

Sonic the Hedgehog 2

Octus sprite-1-

Octus in Sonic the Hedgehog 2 is seen sitting on the ground in Oil Ocean Zone, mostly seen on stair sections of the zone. There can be also be one or two Octus Badniks in one area as well. When it sees the player, it quickly starts hovering in the air by spinning its tentacles, a few seconds later it stops moving up and shoots one, small energy projectile straight ahead and lands to the same place repeats its pattern after for while.

The player has to avoid Octus and its energy projectile while moving forward, although due the fast speed, it might become challenging. Despite that, the player is able to destroy these Badniks by using a Spin Jump or quickly doing a Spin Dash.

Sonic Free Riders

Octus makes a reappearance in Sonic Free Riders as a power-up item. It has a slightly different look as it has a red switch on its head, which by pressing it activates the feature. The game features two variations of the Octus Badnik, that can be found in item boxes and the player is holding onto its hand. If a player receives an pink Octus, the other players' screens will get distorted with ink. The player must use a wiping motion to get the rid of the ink. When the player holds blue Octus, it gives its user a burst of speed, allowing him/her to catch up to his/her opponents.

Sonic Lost World

Octus appeared in Sonic Lost World, where they serve again as enemies. During the game, it turns out that Badniks, including Octus Badniks, got hijacked by the Deadly Six. While having their original design from Sonic the Hedgehog 2, Octus Badniks are also seen to be able to fire energy projectiles from their snouts.

In Tropical Coast Zone 4, single Octus Badnik can be found sneaking on the surface of the water. In Frozen Factory Zone 4, some of Octus Badniks are seen floating and firing projectiles above the oil fields inside the factory. In Silent Forest Zone 3, they are seen slowly skating with their tentacles towards the player, while firing projectiles.


Physical Appearance

Octus as based on the octopus, it has pink round shaped head, which features white eyes, small corkscrews ears on each side of the head and a tiny snout. The most known feature on Octus is having six mechanical tentacles, which these Badniks can spin around in order to float in the air. These tentacles have small suction cups, which make Octus able to stand on the ground. These tentacles are part of the lower body which is colored yellow in the middle section and blue on the bottom. In Sonic Lost World, Octus badniks have got eyelashes, as they can be considered as female robots.


Octus usually can be seen sitting on the ground motionless with an angry stare until the player approaches it. Once it spots the player, Octus will open its eyes wide and starts floating in the air until it starts moving and shoots its small, yellow projectile out of its small snout. It then moves back to the ground and repeats the same pattern. In Sonic Free Riders, Octus is seen able to shoot black ink instead of the energy projectile.
