Summer Smith

Summer Smith (Spencer Grammer) is the sassy teenage sister of Morty Smith (Justin Roiland) and granddaughter of mad scientist Rick Sanchez (also voiced by Justin Roiland) in Adult Swim’s Rick & Morty. While she and Morty often fight in the way that siblings do (or perhaps to a greater, more chaotic extent thanks to the ordeals their grandfather gets them into), the pair really does care for each other, although Summer often expresses jealousy in not experiencing the same adventures.
