Space Bully Nebulax is the main antagonist of the Astro Bot series. He is the leader of his goons, the boss of Mighty Chewy, Wako Tako, Lady Venomara, Mecha Leon, Falcon McFly, and the archenemy of the titular character. Nebulax first appears at the start of Astro Bot Rescue Mission, where he steals the Headset from Astro's ship. This not only causes Astro's friends to be scattered throughout the Galaxy, but also the destruction of the ship which leads Astro to need the player's help. To stop Astro from going after him, Nebulax sends his army of Robot Soldiers after him, led by his equally tyrannical gang. The rest of the game is spent chasing him down while saving the other Bots and fighting Nebulax's gang of mechanical beasts until Astro finally confronts him in a final battle between Astro and Nebulax, the latter uses his version of a PlayStation controller, which he uses to attack Astro and the Player. If Astro evades his attacks long enough, he will try to crush Astro with his controller, which gives him the chance to attack Nebulax's hand. This gives the Player the chance to steal his weaponized controller and attack him with it. Doing this three times leads to the controller being equipped with a Blaster, which Nebulax tries to escape by throwing multiple enemies at the Player and Astro. Doing this long enough leads to the Controller charging Up a Laser which directly hits Nebulax and blasts him away at the other end of the Galaxy. This results in Nebulax's UFO exploding into a massive supernova which seemingly kills Nebulax and sends the headset back to Astro and his ship, the latter of which repairs it.
