He is a megagenius scientist whose alcoholism and reckless, nihilistic behavior are sources of concern for "his daughter's" family, as well as the safety of her son, Morty. At the start of the series, Rick had returned to the Smith Family's lives after being absent for an unspecified amount of time, with the reasons for his absence being shrouded in mystery. Rick is a lanky, old man. He has long limbs and is very skinny. He has spiky grey-blue hair with a bald spot on the back of his oblong-shaped head, as well as a prominent unibrow of the same color. He has a droopy nose. His tanned grey skin is wrinkly, with bags under his eyes and a pressure fold above his unibrow that follows its position. He also has laugh lines on both sides of his mouth and wrinkles below each of his butt cheeks. He almost always wears a white lab coat with a turquoise undershirt underneath it, along with brown pants, a dark brown belt with a yellow buckle, and black shoes. Rick is shown to keep a drinking flask and his Portal Gun in each pocket of his lab coat. He is also 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. Rick speaks in a rambling, stammering manner that is often interrupted by belching and gagging, particularly when drunk or high. Rick is a genius scientist, capable of creating complex scientific inventions, including brain-enhancing helmets, dream-invading devices, portals to several different dimensions, cloning technology, cybernetic implants, various energy weapons and force fields, and the world's first amusement park inside the body of a living human. His brilliance can be muddled by his jaded personal views and his alcoholic tendencies. Rick is easily bored and does not do well with routine. When his curse removing store in the episode "Something Ricked This Way Comes" started requiring real work, Rick simply lit the whole store on fire and abandoned it. He regularly goes to other dimensions to harvest resources and will often willingly kill aliens to get them. He is willing to be extremely brutal such as when people betray him or his life or those close to him are in danger. He is usually portrayed as homicidal and having a large disregard for life, enough that he came close to bombing the world with a neutrino bomb while drunk. He was shown to find killing fun during the Purge and was even willing to kill Morty's half-Gazorpian son due to the child's danger to everyone and unstable nature. .
