Rick and Morty

Summer Smith is Morty's older sister from Rick and Morty. She's his 18-year-old older sister, a more conventional and often superficial teenager, is obsessed with anything that can improve her status with her peers. Summer is very similar to her mother, as she is often shown to be very smart and humorous, but is much more selfless. She occasionally expresses jealousy that Morty gets to accompany Rick on his inter-dimensional adventures. In the second season, she accompanies Rick and Morty on adventures more frequently and sometimes will even prove herself to be more competent than Morty.

Summer is a teenage-girl of average height and a thin build. She has a light skin-tone and ginger hair. Her facial features take after Jerry's, having an oval head and pointed nose.
