The Roboheads are round robots about the same height as Sonic the Hedgehog. Modeled after Dr. Robotnik's face, they are mostly yellow in color and feature Robotnik's moustache and his pince-nez black glasses that cover their eyes.
In Sonic Spinball (8-bit), the Roboheads look mostly the same, except that they are much shorter and red in color.
Sonic the Hedgehog Spinball
In Sonic the Hedgehog Spinball, four Roboheads are seen in Lava Powerhouse, hovering inside the Roboiler. In gameplay, the player must get inside the Roboiler in order to damage them. If hit, they will vomit lava. Each Robohead takes five hits to be destroyed. If one Robohead is destroyed, the rest of them will temporally vanish in order to protect themselves, forcing the player to get out the Roboiler. After all Roboheads are destroyed, the player will have cleared Lava Powerhouse.
Sonic Spinball (8-bit)
In Sonic Spinball (8-bit), only two Roboheads appear in Lava Powerhouse. Like in the 16-bit version, they hover around inside the Roboiler, and take five hits to be destroyed. However, if one of them is destroyed, the other one will not vanish, making it possible to destroy the two at the same time. After all Roboheads are destroyed, the player will have cleared Lava Powerhouse.
Powers and abilities
While they do not have remarkable abilities, the Roboheads are able to float around in midair. They can also vomit lava.
- In Sonic Spinball (8-bit), each destroyed Robohead gives the player 5.000 points, and after destroying the two, the player will receive 1.000.000 points.
