*Mari-An is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. She is a female mobian echidna, formerly from the Lost Tribe of Echidnas, and the wife of Rob O' the Hedge. A formidable warrior, Mari-An helped free the Lost Tribe from the High Sheriff's control. Later, when the Lost Tribe arrived on Albion, Mari-An remained in the Kingdom of Mercia to be with Rob, with whom she eventually had a child named Jon O'Hedge.

Mari-An is a red-furred mobian echidna with blue eyes. She is seen wearing a blue scarf around her neck, a green-ish cloak tied up, and blue shoes.

Like Julie-Su, Mari-An is more aggressive than typical female Echidnas. She takes issue with those who doubt her self-reliance; when Knuckles questioned her ability to handle herself in a dangerous situation, she responded by throwing him to the ground.Similarly, she doesn't like being left out of the action, likely seeing such a request as doubt of her capabilities. While initially not impressed with Rob's bravado, she quickly grew to love him. She shows great concern for others and doesn't hesitate to put herself in danger for their sake; she fears for their safety far more than her own. When Rob leaves her to keep an eye on things back home, she isn't completely pleased with being left behind, but is understanding and accepting of the situation.*
