Rexxon

Rexxon was a robotic snake-like monster that first appeared in Sonic the Hedgehog #6, in the Toxic Caves of the Veg-O-Fortress. Rexxon grabbed Sonic the Hedgehog by the fur, when he entered the fortress, and took him to the level boss, Scorpius. Scorpius and Rexxon were quickly beaten by Sonic, though.


 * Rexxon is named after the gas station, Exxon, considering that he was slithering in oil.
