Mortimer Chauncey "Morty" Smith Sr. of the Prime Dimension is the titular deuteragonist of Rick and Morty.

== Appearance == Morty is 14 years old, stands at 5'2" (158 cm), and weighs around 110 lbs (50 kg). He has a medium complexion, short brown hair, and a small, droopy nose. Morty's head is round and roughly in the shape and size of a circle, unlike many other characters in the show. He also doesn't have a visible neck. He typically wears a yellow shirt, blue pants, and white shoes.

== Personality == Morty is Rick Sanchez's grandson and is often forced to tag along on his various misadventures as a sidekick whilst attending Harry Herpson High School along with his sister, Summer. At the beginning of the series, Morty is shown to be an incredibly anxious and submissive teenage boy. He had little say in the adventures he went on with Rick and was often verbally abused and manipulated by him. However, Morty eventually gained more confidence as time went on and is now more capable and independent rather than a mere sidekick. This newfound confidence also allowed Morty to distance himself from Rick more often due to his despicable tendencies, although Morty still stays by his side when necessary.

Morty also has a pronounced stutter (even when calm), and his voice constantly breaks due to the effects of puberty. However, as the series has progressed, Morty's stutter seems to occur less frequently.

== Trivia ==

• Morty's birthday is on February 6th, making him an Aquarius.
• Despite being one of the least intelligent members of his family, Morty has shown moments of cleverness and ingenuity.
• Morty has a darker alter-ego known as "Evil Morty", who originated from a different dimension.
• Morty harbors a long-standing crush on Jessica, a classmate, although their relationship remains mostly one-sided.
• He is one of the few characters in the series who consistently shows a strong moral compass.
• Justin Roiland originally voiced Morty until 2023; the role has since been recast.
