• Rick Prime

The real name is Rick Sanchez, he is 196 cm and 27 years old, He was the Rick who was responsible for the deaths of Diane in every single dimension, and Beth Sanchez in Dimension C-137[4]. Rick C-137 attempted to find and kill Rick Prime throughout the multiverse for decades, killing countless other Ricks in the process. Rick C-137 eventually landed in Rick Prime's original dimension and took his place, kick starting the events of the series.In "Solaricks", Rick C-137 resets portal travelers, thereby sending Rick Prime back to his original dimension. In this episode, Rick Prime is seen in his space-station taunting Rick C-137, before being launched back onto Earth. Rick Prime then encounters Jerry Prime and kills him.In "Unmortricken", it is revealed that Rick Prime invented a weapon known to some Ricks as the Omega Device (thought Rick Prime claims that the device is "too cool for a name"), which has the power to erase an individual from every dimension, as well as interfere with other people's memories of that individual. This weapon was used on Diane, which explains her absence from the series. Rick C-137 and Evil Morty temporarily join forces, and managed to track down Rick Prime. They engage him in a vicious fight, which they barely win. Evil Morty then steals Rick Prime's schematics for the Omega Device before giving Rick C-137 the opportunity to kill his nemesis. Rick Prime, defiant to the end, ceaselessly mocks Rick for becoming like him as he is slowly beaten to death.Following Rick Prime's death, Rick C-137 briefly became depressed as he no longer had a goal now that his nemesis was dead. However, Morty was able to intervene and encourage Rick to resume their regular adventures once again. Rick Prime's legacy briefly lived on with Evil Morty, who took the plans for the Omega Device and used them to threaten Rick C-137, lest he put an end to the "Rick experiment", before Rick C-137 took advantage of Evil Morty's complacency and used the Omega Device.
