Sonic the Hedgehog/Badniks

All names are taken from the American game manual unless otherwise stated.



Motobug - Beetle robots that simply roll back and forth across the ground and pose no immediate dangers to Sonic. This enemy only appears in the Green Hill Zone.



Chopper - Piranha robots that jump from underneath bridges. Caution when approaching a bridge is advised, as well as possibly jumping while crossing it. They are only found in the Green Hill Zone.



Buzz Bomber - Robots that fly across from the right or left side of the screen, occasionally pausing to fire a single, large flashing projectile downward. Can be ignored and avoided most of the time, with the safest place to attack them from being above. They are found in the Green Hill, Marble and Spring Yard zones.



Newtron - These chameleon robots appear on the side of cliffs but are invisible until approached. Blue Newtrons transform into missiles and fire themselves along the ground, while green Newtrons make themselves visible just long enough to fire a single, large flashing projectile at Sonic. They appear in the Green Hill zone only.



Caterkiller - Caterpillar bots that crawl back and forth along the ground. Their only weak point is the head, which can be jumped on or rolled into. Hitting them anywhere else will not only result in losing all your rings, but their four segments will scatter and bounce around the area and risk causing more damage. They appear in the Marble and Scrap Brain zones.



Roller - Spherical robots that typically appear from the left side of the screen down long declines. They cannot be destroyed in their spherical form and roll faster than Sonic can run, and they also hold the ability to jump in this form, so fast reactions are needed. At random intervals, they stop and briefly open up - This is the only chance to attack. They can be found in the Spring Yard zone only.



Jaws - Piranha robots that move about underwater, and dive at Sonic directly if he approaches. They can be found in the Labyrinth zone and the third act of the Scrap Brain zone.
