The Dr. Robotnik Head (official name unconfirmed) is a toy that first Wolf O'Donnell and then Mario found in SMG4: If Mario Was In... Starfox (Starlink Battle For Atlas). Dr. Robotnik Heads are plentiful on the planet Sonatus and serve as its power source due to their meme status. Wolf wanted to harvest them to make his army more powerful, but Mario, Mason, and Fox McCloud stopped him. It made a cameo in SMG4: The Melancholy of Fishy Boopkins.
