Jimmy McGill uses the professional name Saul Goodman after becoming a lawyer in Better Call Saul.
The name becomes central to Jimmy's transformation from a struggling public defender into a flashy criminal lawyer. He introduces the Saul Goodman identity through advertising, colorful suits, and aggressive courtroom tactics. The name also connects the prequel series to Breaking Bad, where Saul Goodman represents Walter White and Jesse Pinkman.
The phrase is a pun on “It's all good, man,” reflecting Jimmy's talent for turning language into salesmanship. Although Saul presents himself as a separate persona, the series shows that Jimmy's choices, relationships, and insecurities remain beneath the performance. Gene Takavic is the later identity he adopts while hiding in Omaha, not his professional name in Albuquerque.
