Season 1.
Meanest of all the Mean Girl types, she was the Captain of the Cougarettes, a witty, cruel girl with a very barbed tongue. Desired by Duckie Walker she tried to play Cord Van Graff and Fionn Corvin against each other.
She was captured by Phobos at Duckie's beachfront party launching Fionn, Cord and Barbie's rescue mission.
In The Invasion of the Oneroi Fionn discovered Mercedes's alternate (and in some ways former) self to be a dorky larp enthusiast with a weight problem. This humanized her greatly and though they continued to have an antagonistic relationship, Fionn always felt some empathy for her from then on.
Season 2.
After breaking up with Cord Van Graff she became involved with Andrew Anderson, an Abrahamic Scion.
At Fionn's Halloween/17th Birthday Party Mercedes saw Andrew Anderson be unfaithful to her with Aphrodite and went to her mother Nyx, who encouraged her to embrace her aspect of Strife, as the goddess Eris.
Soon after this, a very distressed Mercedes started to become friends with Fionn. She did not want to be Eris, she wanted to overcome her insecurities and become a better person. She became a source of inspiration to Fionn, helping him form his philosophy that the gods and the children of the gods must be capable of more than their aspect, or else they are slaves or monsters.
Later in Season 2 Mercedes began to display a more playful tendency towards mischief, a fondness for victimless pranks beginning to surface. Fionn and her spoke often, Fionn feared his own bloody Aspect and she was recovering from her cruel Aspect. Fionn found speaking to her helped him put things in perspective, saying to her that as The Godkiller, he really needed the balance provided by Mercy.
From then on he started calling her by that name and she eventually adopted it herself.
At the end of Season 2, she became a part of House Corvin as Mercy, goddess of Change and Clemency.
Season 3.
Mercy attends Clearwater Community College as a student, with a major in psychology and a minor in communications. She is a Radio DJ, and host of the 'Oh, Mercy!' show, on CCC-FM.
