Mari-An

A female Echidna of the Lost Tribe of Albion, Mari-An first appeared when the tribe arrived in Mercia. To her shock, Mari-An discovered that her brothers, Zax and Raynor, had disappeared. Accompanying Knuckles the Echidna, she set out to find them. The two later split up, and upon their reunion, Knuckles was accompanied by Rob O' the Hedge.

Rob and Mari-An's similar personalities led them to fight atop a log over a nearby river. Mari-An fought to a tie Rob, and the two fell in love. Meeting up with Sonic and Tails, the quintet worked together to save the Tribe from slavery and guide them to Albion. After that, Mari-An decided to remain in Mercia with Rob, whom she later married with the complete approval of her parents. The two later had a child.

Like Julie-Su, Mari-An is more aggressive than is typical of female Echidnas. When Knuckles questioned her ability to handle herself in a dangerous situation, she responded by throwing him to the ground. As demonstrated by her fight with Rob, she possesses a number of fighting skills that make up for her lack of special abilities.

Mari-An's name is clearly a pun of Maid Marian, the romantic interest of Robin Hood, with Rob and Mari-An serving as an Archie parody to the classic story. Their initial meeting and love story, however, is clearly based on Robin Hood's first meeting with Little John.
