Nebula

Sonic the Hedgehog 2 (16-bit):
Nebula is an Badnik that hides in the inside of a metal egg-shaped dome. It appears in Sky Chase Zone in Sonic the Hedgehog 2 (16-bit).

Attack Pattern:
While the screen side-scrolls, Nebula will appear along with Balkiry's and Turtloid's. This Badnik will wait for the player to approach, and will float upwards. Then, it will shoot mines from its shooter on the bottom. These Badnik's are easy to eliminate though, for the player can take control of Tails's plane, and Sonic can attack it.

Sonic the Comic:
Nebula Badnik's are sent on sky patrol missions in issues of the British Publication of Sonic the Comic.
