Biography
Arthricia first appeared in the episode Look Who's Purging Now, where she was one of the people on the Purge Planet. She was seen getting cornered and about to get killed during the purge until Morty spotted her. He convinced Rick to fly down there and save her. So he did. When they saved her, Arthricia explained that she disagreed with the politics of the purge and always wanted to put an end to it. She then lied to Rick and Morty, saying that her nana was left on the planet and they needed to save her. They went back down into a shed and Arthricia stole Rick's laser gun and shot him in the liver and took off in his ship without him, leaving Rick and Morty to fend for themselves.

Rick and Morty later found Arthricia again and angry about what she did before, Morty threatened to kill her. Rick stopped him and Arthricia explained that she stole his ship because she wanted to kill the rich people who came up with the idea of the purge and forced society to comply with it. Rick helped Arthricia by giving her one of the war suits and they both broke into the mansion where the rich people lived and slaughtered them all.

In the end, Rick and Arthricia had freed their world of the purge. Morty asked Arthricia out, but she told him that she already had a boyfriend. So, he and Rick left, and Arthricia lived peacefully with the rest of her people for a few seconds, until they started to argue about politics again and started killing each other.
