Rick is easily bored and does not do well with routine. His brilliance can be muddled by his jaded personal views and his alcoholic tendencies. Rick is a genius scientist, capable of creating complex scientific inventions, including brain-enhancing helmets, dream-invading devices, portals to several different dimensions, and the world's first amusement park inside the body of a living human. He would later orchestrate a massive escape attempt, leading to the elimination of the Council of Ricks, significant damage to the Citadel and the destabilization of the entire Galactic Federation's economy.
In the episode "The Wedding Squanchers", Rick willingly turned himself over to the Galactic Federation and was sent to one of their maximum security prisons. In the garage, he works on his inventions and scientific formulas, and tests them out - traveling to other dimensions, building various robots and devices, and causing general mayhem in different parts of the universe, be it dimensions, planets, or alternate realities. Rick is about 60-70 years old and currently resides in his room in the Smith house. In the episode Get Schwifty, it was revealed that when Rick was somewhere in his college years or in his 20's, he, Birdperson, and Squanchy were in a rock band called "The Flesh Curtains". In the same episode, he and Morty leave their original dimension (Dimension C-137) in favour of the one they currently reside in. Nevertheless, she is absent from his life.
This could imply that the woman he married before is either divorced and/or deceased as of now. In the episode Rick Potion #9, it is revealed that Rick has a very pessimistic worldview, informing Morty that love is "just a chemical reaction that compels animals to breed", advising him not to continue the cycle of love, marriage and heartbreak that he had to go through and that his parents would likely go through, and instead encourages him to direct his energy towards science. In the Pilot episode, Rick told Beth that he loved the eggs that she made him and that her mother would have loved them too if she were still there. The reason for his absence is unknown to the rest of the family. It has been mentioned multiple times that Rick has been absent from the family for at least fourteen years, and it wasn't until one year before the events of "Something Ricked This Way Comes" when Rick finally returned to the Smith house on January 15th. Not much is known about Rick's life before his current state seen in the show except for a few things that have been vaguely mentioned in the series. Rick speaks in a rambling, stammering manner that is often interrupted by belching and gagging, usually from being drunk. He is occasionally seen with some green spill on his mouth, showing up mainly when he is drunk, or during a rare chance where he throws up. He also wears brown pants, a dark brown belt with a yellow buckle, and black shoes. He wears a white lab coat with a light blue undershirt underneath it. His face is wrinkly as he has bags under his eyelids and a pressure fold above his unibrow that follows its position and laugh lines on both sides of his mouth. He has spiky blue hair on his head and a unibrow. He has a dimly tanned ashy complexion and grey-blue hair with a bald spot on the back of his head.
He has long legs and arms, and is very skinny.
He is later revealed to be Morty's cousin in an interview with Roiland himself. He is a genius scientist whose alcoholism and reckless, nihilistic behavior are a source of concern for his daughter's family, as well as the safety of their son, Morty. Rick is one of two main characters in Rick & Morty
