Sonic the Hedgehog 3 will introduce Maria Robotnik, but who is this character in canon, and what does she have to do with Shadow the Hedgehog? The reveal that Maria would be joining the cast of Paramount's live-action Sonic franchise is intriguing, especially since this character is at the center of one of the darker storylines of the video games and comics. As can be gathered by her last name, she is related to the villain Dr. Robotnik, AKA Dr. Eggman. However, it's sure to be seen in Sonic the Hedgehog 3 just how unlike the mad scientist Maria really is.
