Grounder

Grounder is one of the main antagonists of the television series Adventures of Sonic the Hedgehog. He made his SMG4 debut in "Sonic the Derphog: Egg and Peach.".

Background
In his Sonic the Derphog debut, he was seen agreeing with Scratch that Princess Peach wasn't too interested in their boss. However, this failed when Peach asked Dr. Eggman if he would be the father of their babies, which caused Grounder to explode. Grounder was later seen crying at Peach and Eggman's wedding along with Scratch.
