Nebula (ポトス,Potosu?) is a Badnik created by Doctor Robotnik, that first appears in Sonic the Hedgehog 2. It is small green Badnik that controls the black armor, that has propeller on top of it in order to fly in the air and is able to bombing its target down by dropping small spike balls at the bottom.
Sonic the Hedgehog 2
First appearing in Sonic the Hedgehog 2, these Badniks are featured at Sky Chase Zone, where the player controls Sonic with his Tornado that is piloted by Tails (and vice versa). Nebula Badniks are always hovering in the same place and then they start to move up to and above the player as the player comes closer. It will later then hover down when the player has gone over and past them. If the player get below them, they start dropping spiked balls on to the player.
There are different formats of Nebula Badniks being set in the air. The first Nebula that the player sess, is flying alone, but the rest attack in groups of three to seven. The most general formation are three on the row and near end of the zone. The player can easily destroy Badniks by Spin Jumping straight at them.
Sonic Pocket Adventure
Nebula Badniks also make an appearance at Sky Chase Zone in Sonic the Hedgehog Pocket Adventure. Nebula Badniks behave identically as they did in previous appearance and drop spiked balls from the bottom. There are mostly on same formats, even through these Badniks are seen on two or three rows.
In Sonic Runners, the Nebula is one of the enemies encountered during the game's stages. Like other enemies in the game, they come in their regular variant, a gold variant that grants extra points when destroyed and a dark grey variant that can only be destroyed by Power Type characters.
Nebula Badniks look like a small green and orange creatures, that are hiding and controlling inside an black, egg-shaped shell of metal with a hole beneath it. It is unclear what these creatures look like fully, but they are known to have eyes and hands. It flies using a yellow propeller on top of its black shell, and it seems to be clutching a pair of control levers. At the bottom of shell, there are small cannon, where small creature will eventually drop spiked balls.
Nebula hovers in place waiting for the player to approach. When Tornado comes close to it, the Nebula flies upwards a little and drops small, flashing spiked balls from a shoot on its underside. These Badniks can be found on different formats, that are mostly two or three on rows. Aside from these, Nebula Badniks are relatively harmless, although they frequently appear in groups.
