Heavy King

Heavy King is the leader of the Hard Boiled Heavies.

History
The Heavy King was originally an elite Egg-Robo who handled the most extreme tasks for his creator, Dr. Eggman. After detecting a mysterious energy source on Angel Island, Dr. Eggman sent the Heavy King and his Hard Boiled Heavies to investigate.[4] Upon reaching Angel Island, he and his troop excavated the energy source, the Phantom Ruby, just as Sonic the Hedgehog and Miles "Tails" Prower arrived. The Phantom Ruby promptly warped space-time around them, transforming the Heavy King into his royal-esque attire along with his troop. As a side effect of the ruby, the Heavy King and his team gained free wills and personalities of their own, though they were driven mad in the process.
