The kids’ mother, Beth, is a generally level-headed person and assertive force in the household, though self-conscious about her professional role as a horse surgeon. Morty’s 17-year-old sister, Summer, is a more conventional teenager who worries about improving her status among her peers and sometimes follows Rick and Morty on their adventures. He frequently goes on adventures with his 14-year-old grandson, Morty, a kind-hearted but easily distressed boy, whose naive but grounded moral compass plays counterpoint to Rick’s ego. Rick is an eccentric and alcoholic mad scientist, who eschews many ordinary conventions such as school, marriage, love, and family. Although Beth welcomes Rick into her home, her husband, Jerry, isn’t as happy about the family reunion. After having been missing for nearly 20 years, Rick Sanchez suddenly arrives at daughter Beth’s doorstep to move in with her and her family.
