Mari-Su

Mari-Su was the second wife of Luger, the Dark Legion's third Grandmaster, and mother of Julie-Su.

Luger's Second Wife
Some time after Luger's first wife Merin-Da passed away, he came across the gentle Mari-Su and was immidiatly captivated. Despite objections from his children Kragok and Lien-Da, Luger persued a relationship with her and eventually the two married. A year later, Mari-Su gave birth to Julie-Su, much to the dismay of Kragok and Lien-Da. (SSS: #11)

Seeing her as a threat to their ambitions, and feeling jealousy for what they felt was her taking their mother's place, Kragok and Lien-Da organized the assassination of Mari-Su, making it appear to be a tragic accident. Julie-Su was then entrusted to the couple Simon and Floren-Ca, as Luger was too busy with work to raise her. Not long afterwards, Luger also disappeared, and Kragok and Lien-Da had Julie-Su's memory erased. (SSS: #11)

Background Information
Mari-Su was only ever seen in Sonic Super Special #11. While the issue makes it obvious Mari-Su's death was organized by Lien-Da and Kragok, the fate of Luger remained anonymous. Sketch designs from Patrick Spaziante for Mari-Su as well as Merin-Da and young Kragok and Lien-Da were available later in a Sonic the Hedgehog issue.
