PERSONALITY

 Diane Sanchez is characterized as a sharp-tongued, witty, and grounded individual who found Rick's nihilistic humor funny. She is portrayed as a stabilizing, affectionate, and intelligent counterpart to Rick's chaotic personality, serving as the emotional anchor for his early life.

BIOGRAPHY

Diane was Rick's wife and Beth's mother. Not much has been revealed about what her relationship with Rick was actually like due to conflicting statements over the course of the series. However, it can be discerned that they had a happy marriage, as shown in the (only partially fabricated) flashback in "The Rickshank Rickdemption". Mr. Nimbus appears to have known Rick long enough to at least know who Diane was, although it is unclear if he actually met her (as shown in "Mort Dinner Rick Andre").

However, Rick's marriage to Diane was ruined when another Rick, annoyed at Rick's refusal to explore the universe like other Ricks, murdered Diane and a young Beth using an explosive that destroyed Rick's house. As shown in "Rickmurai Jack", Rick spent the next several decades of his life systematically murdering various Ricks across the multiverse, trying to find the one who took his wife and child away from him. However, he was unsuccessful in his endeavor, and after founding The Citadel, he decided his best bet was to instead settle down in the dimension the other Rick came from. Since that Rick had abandoned his family, Rick reasoned he could give them the relief of having him back in their lives while also allowing him to wait for that Rick to return so he could finally have his revenge.

Rick avoids revealing much about his relationship with Diane to Morty for a good portion of the series. He even avoids telling the audience, deliberately pretending the backstory from "The Rickshank Rickdemption" is fabricated and interrupting Mr. Nimbus from establishing a "canonical backstory". Eventually, Morty finally learns about it in "Rickmurai Jack" due to the actions of Evil Morty and tries to sympathize, but Rick brushes it off and says "Now everyone can shut up about it."

As revealed in "Solaricks," at some point over the years Rick created an AI-version of Diane to "haunt" him at his old house in Dimension C-137. This AI would always sound like she was calling to him from the other room, constantly reminding him of his failure to save her and urging him to get revenge on her and Beth's murderer. Rick re-encountered this AI when he was returned to his home dimension after trying to reset his portal fluid, where he declared it was time for him to move on from her and Beth's deaths as he now had a family in a different dimension to care for. However, the Diane AI reasoned that, if Rick had reset by Rick's portal fluid error, Rick Prime would also have been reset to the Prime Dimension. Rick nearly started his revenge quest once more but was talked out of it by Morty, unaware that the Diane AI had been correct.

As revealed by Rick Prime in "Unmortricken", after killing Rick C-137's Diane, he repeated the process on the Dianes of other Ricks who had likewise turned down his offer before eventually using a weapon called the Omega Device to kill Diane in every universe across infinity. As a result, Diane is deceased in all of the dimensions Rick settled in, including the Prime Dimension, Dimension C-131, and the Parmesan dimension. When other Ricks began hunting Prime in revenge for killing Diane, Prime built a Saw-style trap to take care of them, deploying a kill-bot wearing Diane's face as a final foe. After Rick C-137 survived the trap, he managed to track down Prime and finally avenge Diane by killing his counterpart.

In "Fear No Mort", Morty ventures into a Fear Hole, during which he and Rick encounter a version of Diane who survived the bombing due to her Rick sacrificing himself. Morty easily guesses that she (along with, he later learns, the Rick who ostensibly followed him) is a manifestation of the Fear Hole, given the Omega Device would negate any possibility of Diane coming back. The real Rick learns of her appearance later on and briefly considers jumping into the Fear Hole in hopes of seeing Diane one last time, but decides against it.
