Summer Smith

Summer Smith is one of the main characters of the American animated television series "Rick and Morty". Created by Justin Roiland and Dan Harmon, Summer is a conventional and often superficial 17-year-old teenager, who is obsessed with improving her status among her peers Known for her smart and humorous personality and for her high dexterity, the character has been well-received. She is the well-meaning and intelligent older sister of Morty Smith and granddaughter of mad scientist Rick Sanchez.
Following Rick and Morty abandoning their original reality in the first season episode "Rick Potion #9", a new Summer identical to the original is introduced; the original Summer is shown to be ruling a post-apocalyptic wasteland with her parents in the third season episode "The Rickshank Rickdemption" and the "Rick and Morty" comic series, the latter of which additionally establishes Summer to be pansexual, a character trait later incorporated into their television series depiction.
Biography.
Summer is 17 years old and is a student at Harry Herpson High School along with her younger brother Morty. She occasionally expresses jealousy that Morty gets to accompany Rick on his inter-dimensional adventures, whom she sees as a hero, though he is often contemptuous and dismissive of her teenaged life perspective and values. As the series progresses, Summer begins accompanying Rick and Morty on their adventures and is trusted with restoring their memories in the scenario of the pair being rendered amnesiac.
Development.
Addressing the character's "gradual" evolution from side character to main character over the course of the series and Dan Harmon's attribution of her vocal performance to the character's increased role in an interview with "Looper", Summer Smith voice actress Spencer Grammer stated that:
"I maybe wasn't necessarily aware that I was having that kind of an influence at all [on the character], but I love voicing Summer and I love acting. So it's really lovely when you do something that you love and other people can find inspiration from that too."
Reception.
The character has received positive reception. "The Mary Sue" praised Summer as "the most interesting female character to ever appear on Adult Swim [and] a great example of powerful, funny feminine youth." "The A.V. Club" praised "[how] Summer develop[s] from the fun, quippy side character to a notably more active participant in the intergalactic shenanigans and a strong thinker" over the course of the series, stating that "what makes her so fascinating is that some of the things that would be vilified in other young female characters often make her the smartest person in the room. The fact that she’s concerned about being social and popularity makes her the most personable. She tends to have a better understanding of how people work than anybody else." "Inverse" declared that "Without a doubt, Summer is the most relatable character on "Rick and Morty"", while "SyFy" described her as a better main character than their brother Morty, praising her increased role in the series as it goes on.
VerbStomp described Summer as "[one] of those girls in high school everyone hated, but simultaneously tried to "be" [and] primarily concerned with increasing her status amongst her peers, and [classmates] — she’s a necessary trope that adds to the dynamic of the Smith family."
