Mari-Su of the House of Atrades is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. She was the second wife of the Dark Legion's third Grandmaster Luger and the mother of Julie-Su.
Several years after the death of Merin-Da, Mari-Su was found by Luger, who was captivated by her immediately. A while after meeting Luger, Mari-Su married him, and a year later she gave birth to Julie-Su. However, Mari-Su was despised by her step-children Lien-Da and Kragok, and she was eventually assassinated by Lien-Da in a way that made her death appear as a tragic accident.
- Her name is derived from the term "Mary Sue", which fits Lien-Da's view of her as a sickeningly perfect being.
- Mari-Su's house name "House of Atrades" is a parody of the "House of Atreides" from the Dune series.
