Dr. Ivo Robotnik (also known as Dr. Eggman) is an evil scientist and dictator who seeks to rule over the entire world and turn it into his personal Eggman Empire. In the Vultroverse, he is often an indirect (and occasionally direct) cause of many of the conflicts faced by Vultro the Fox.
History
Sometime between 5-10 ABV, Robotnik constucted E-112 Sigma, who would break free of his command and become Databyte Egg. He would continue to track the rebellious robot as it changed its directive and traveled to Eilaela, leading him to learn of the existence of Solidus the Werewolf.
It wasn't long before Robotnik began to monitor and spy on Solidus, trying to learn what his plans were. In 28 ABV, he overhears a discussion between Solidus and Otto Octavius, learning of the existence of Infinity Stones in the universe. Unfortunately, the stones had been silently destroyed hundreds of years ago. He decides to go back in time to the 21st century to attempt to steal them, contacting Octavius and forming the Sinister Six. (Story:Vultro and the Spider-Women)
