For other uses of the term, see Octus (disambiguation).

The Octus[1] (オクター[2] Octar?) is an enemy that appears in the Sonic the Hedgehog series. It is a mass-produced, octopus-based Badnik created by Dr. Eggman that can float in the air and shoot energy projectiles from its small snout.


Octuses are based on the octopus. They have pink round heads with black eyes, small corkscrews ears on each side of their heads and a tiny snout each. Their most noticeable feature are their six mechanical tentacles on their lower body which they can use as a propeller. These tentacles have small suction cups on their ends. Also, their lower body, where their tentacles connect, are yellow on the middle section and blue on the bottom. In Sonic Lost World, the Octuses received eyelashes and cyan eyes.

Game appearances

Sonic the Hedgehog 2 (16-bit)

The first appearance of this Badnik was in the 16-bit version of Sonic the Hedgehog 2, where it served as an enemy. This time around, this Badnik is referred to as Octus[1] (オクター[2] Octar?). In this game, the player encounters them in Oil Ocean Zone.

In gameplay, Ocutuses appear sitting on the ground motionless (with an angry stare no less), mostly at stair sections. In these areas, there can be up to two Octuses in one area. When seeing the player however, the Octuses will start hovering up in the air by spinning their tentacles and then shoot one, small energy projectile in a straight line ahead. They will then land in the same place as before to repeat their attack pattern after a while. The player has to avoid the Octuses' projectile while moving forward. Other than that, the player can destroy these Badniks with either a Spin Jump or Spin Dash. Also, upon their destruction, they release an Animal.

Sonic Free Riders

In Sonic Free Riders, the Octus makes a cameo appearance in the form of two different Action Items which can be obtained from Item boxes: Octo-Ink and Octo-Boost. Each item resembles a minature version of the Octus, but with a button on top. In gameplay, the Octo-Ink can obscure opponent's view with ink, and the Octo-Boost can provide the user with a brief speed boost.

Sonic Lost World

In the Wii U/PC version of Sonic Lost World, the Octuses served again as enemies. During the game, all Eggman's Badniks, including the Octuses, got hijacked by the Deadly Six. In this game, the Octuses mostly retained their original design from Sonic the Hedgehog 2.

In Tropical Coast Zone 4, lone Octuses can be found sneaking on water surfaces. In Frozen Factory Zone 4, some Octuses will float up from oil pools inside the factory section and fire projectiles. Finally, in Silent Forest Zone 3, Octuses will skate with their tentacles towards the player while firing projectiles.

Mario & Sonic at the Rio 2016 Olympic Games

In Wii U version of Mario & Sonic at the Rio 2016 Olympic Games, the Octuses appear as hazards. In this game, they retain their design from Sonic Lost World.

In gameplay, two Octuses serve as hazards in the Duel Beach Volleyball event. During this event, a plaform with two Octuses sitting on it will occasionally move in-between the fences in the center of the field. From there, the Octuses will spit out projectiles upwards or towards players. These projectiles can stun the playable characters (as well decreasing their duel points by twenty points) or change the flight direction of the volleyball.

Sonic Mania


In Sonic Mania, and its expansion Sonic Mania Plus, the Octuses appear as enemies. In terms of design, they look like they did in Sonic the Hedgehog 2. In these games, they only appear in Oil Ocean Zone.

In gameplay, these Badniks behave like in their debut game: upon spotting the player, they will hover up, shoot a small projectile straight ahead, and then land in the same place to repeat the pattern. Other than that, the player can destroy these Badniks with either a Spin Jump or Spin Dash. Also, upon their destruction, they release an Animal. Additionally, the main boss of Oil Ocean Zone features Dr. Eggman piloting a submarine that takes the appearance of a large Octus.

Powers and abilities

Octuses are capable of flight and can shoot small, yellow energy projectile from their small snout.
