Synopsis
Scratch and Grounder’s vacuum-ray grabs a boulder instead of Sonic, and then the doctor’s Egg-O-Matic, which lands on top of them. Robotnik decides that good help is impossible to find – so he will build it himself, in the form of a son as mean and sneaky as he is.
Robotnik Jr. is the result, and his father sets about teaching him the family business while preparing a plan to blot out the sun and kill off all life and nature on Mobius.
Then Junior meets Sonic, and finds the hedgehog nicer than his dad. He falls for the natural world his father wants to destroy, and switches sides to help Sonic and Tails thwart the scheme, much to Robotnik’s horror.
