Legends of The Multi-Universe[]
Like all villains of Megatron's group, this merged universe had evil winning in its favor, the balance of good and evil breaking. Dr. Robotnik had presumably killed his main hero, Sonic the Hedgehog with help from the other villains, then leaving Tails Prower for dead as the satisfaction of destroying his sworn enemy was enough. Dr. Robotnik was seen conversing with the other villains on how the Children of The Autobots should be dealt with. He is one of the few villains like Emperor Zurg, Sauron, and Darth Vader to never be sent to battle the new heroes of this story.
Defection[]
After witnessing the horrifying betrayal from their master Galvatron, Robotnik and the non-Disney villains that no longer wished to be Galvatron's servants left the Children of Megatron to help the Disney Family, Anime Empire, Hailfire Empire, and the Children of The Autobots fight against Galvatron's remaining forces.
Chronciles of Great New Empire[]
