Rick Prime had more grayish skin than other versions of Ricks, as well as more dull-colored hair in a "nondescript" haircut. He wore a purplish "sci-fi" jacket with a gray shoulder pad and a red shirt underneath. He also wore grayish black pants and appears to have been using the "iPhone 3 equivalent" prototype of the modern Portal Gun upon first meeting Rick C-137. After many years, his appearance was completely unchanged, implying that he either transferred his mind to a cloned body or his healing abilities also give him longevity.Being a Rick, he shares all of his counterpart's intellect and resourcefulness, though he does not seem to indulge in any hedonistic acts like drinking or partying. It is possible Rick Prime is somewhat more intelligent than most other Ricks, as he states that he and Rick C-137 are the only Ricks to ever figure out inter-dimensional portal travel on their own. (All other Ricks having been gifted the technology by Prime himself, or other Ricks whom Prime gave it to.) Like most Ricks though, Prime shows signs of hypocrisy, being willing to kill his original Morty, yet acting shocked when Evil Morty, whom he mistook for his biological grandson, attacked him. In a sense, Rick Prime's personality is what Rick pretended to be for years, a self-absorbed man who didn't care about anyone, upholding the nihilistic philosophy that all other Ricks project. Despite this, he does appear to have some affection for his family. He held some fondness for Slow Mobius, saying that killing him would hurt and having a look of sorrow when he subjected Slow Mobius to the Omega Device. When he thought he met his original Morty, actually Evil Morty, he attempted to make small talk before killing him and later praised Evil Morty's ruthless nature, even attempting an alliance. He also appeared outraged that Rick C-137 had lived in his house with his daughter and grandson. In spite of never officially meeting him, he was fully aware of his grandson's age that showed he at least kept tabs on the lives of his infinite families. Rick C-137 would later state that he had initially sought out Morty purely as bait for Rick Prime, suggesting Prime might have eventually cared enough about his grandson to intervene. Unlike other Ricks though, Rick Prime, as recounted by his daughter, had a horrible relationship with his wife Diane, later mocking his counterparts for being so attached to their "beloved Diane" and Rick C-137 for basing the Space Cruiser's voice on Diane's. Atypically though, Prime did refer to Diane as "our wife" in conversation with Rick C-137, possibly indicating that he retains a degree of attachment for his late wife. In his last moments, he can be heard sobbing, implying there was a part of him that was scared of dying. Unlike most Ricks, he did not display anger when Jerry Prime tried to kill him, instead praising how badass he found the attack. This moment also further demonstrates his coldness, as Rick Prime executes Jerry Prime afterwards, despite him not being able to pose a threat.Rick Prime's life was, to a point, similar to other Ricks, being married to Diane and having a daughter, Beth. As recounted by their daughter, they both had a horrible relationship. He even went so far as to mock his counterparts for being attached to their "beloved Diane" and C-137 for basing the Space Cruiser's voice on Diane's. When Rick C-137 was still pretending to be Rick Prime, he noted in "Rick Potion No. 9" that Rick and Diane Prime had a "failing" marriage — a comment that received no correction or push back from the Smith Prime family. Atypically though, Rick Prime did refer to Diane as "our wife" in conversation with Rick C-137, possibly indicating that he retains a degree of attachment for his late wife. He initially started trying to invent intra-dimensional teleportation technology, but after succeeding he found out that he was the 'last to invent teleportation' as most the rest of the universe already had it. Later he became the first Rick to invent Inter-dimensional Portal travel,[4] a feat that only Rick C-137 managed to duplicate,[5] he abandoned his original family and universe and started introducing the Portal Gun and the existence of the multiverse to other Ricks. . During Rick C-137's search, Rick Prime repeated his offer to other Ricks. When some of them refused, Rick Prime killed their Dianes. As more and more Ricks began hunting Rick Prime, he developed a weapon capable of wiping out all the remaining versions of someone across every conceivable reality, which he used to wipe out all the remaining versions of Diane's.
