Sphere-o-Bot, which goes unnamed in the Japanese version, is the fifth boss of Sonic Chaos, fought at the end of Aqua Planet Zone.
This boss fight begins with a wave of Mecha Hiyokos going after Sonic/Tails. Once they have been destroyed, the Sphere-o-Bot itself will appear and attack the player directly by bouncing around and shooting waves of projectiles similar to the Bouncy Boss Robot. The player must not only avoid being trampled on, but also being shot at, and repeatedly jump on the head as many times as they can.
After hitting the head enough times, the top hemisphere will detach from the body, and the Sphere-o-Bot will resort to firing Mecha Hiyokos like torpedoes at the player. These Badnik missiles fly from everywhere, so the player must be quick on the draw and avoid them at all costs. When they stop firing, the Sphere-o-Bot will return to fire another round of Mecha Hiyokos, and this is the player's chance to land the final hit. After destroying the boss, the player will move on to the final Zone, Electric Egg Zone.
