The Roller (アルマ Arma?) is an enemy that appears Sonic the Hedgehog (1991). It is an armadillo-type of Badnik created by Dr. Robotnik.


Rollers are blue round-shaped Badniks with a red V-shaped horn above their eyes. Their body is a sphere which has been open along the middle like a hatch, revealing a pair of black eyes and small gray three-fingered hands. They also have two mechanical feet and a sharp tail. All their limbs hide inside their body when they assume their spherical form.

Powers and abilities

The Rollers can curl into a ball, similar to the Spin Attack, and travel at high speeds with the intention of plowing through their prey. One screen is not simply enough to notice the Roller, as they can come any moment behind its victim at high speed.



The Rollers' only appearance has been in the original 16-bit version of Sonic the Hedgehog where they can be found in Spring Yard Zone. It is most easy to defeated when it stops and opens tis casing to check the surroundings. They can also be defeated with a Spin Attack whilst moving (albeit with some difficulty).

Rollers have a tendency to plow through Sonic when the player least expects it, but the player should be particularly wary when crossing areas with steep hills as these places are where Rollers are more common.

Keep glitching guys

Glitched Roller graphics.

  • In Spring Yard Zone, for odd reason, the Roller's sprites may start to get messed up (looking like part of a Caterkiller's head), which may be a graphical glitch in the game. This happens if the player keeps following it for while.
  • Rollers bear some similarities to Sonic the Hedgehog: Both have a blue and red coloration, are able to curl into balls, and can move at high speeds. They seen being able to do both Spin Attack and Spin Jump, as they do this from a short distance and then disappear from the screen. It is not known whatever these are classified as same moves that Sonic uses.
  • It can be noticed that the Roller has similar-looking legs as the Ball Hog and Bomb in artwork illustration.
  • Roller is one of the Badniks (along with the Bat Brain) that has not made an appearance in the 8-bit version of Sonic the Hedgehog, since Spring Yard Zone does not appear in 8-bit version. Unlike the Bat Brain, none of the Roller's sprites are not found from game's data.
    • Roller is the only badnik from the original Sonic the Hedgehog that has not made any game appearance since its introduction.
