Breaking Bad is an American television series created by Vince Gilligan. The following is a list of characters from the series.

Walter Hartwell White (also known by his clandestine alias Heisenberg) (played by Bryan Cranston) is an underachieving Albuquerque, New Mexico high school chemistry teacher who, after being diagnosed with lung cancer, starts manufacturing methamphetamine to provide for his family upon his death. Knowing nothing about the drug trade, he enlists the aid of his former student, Jesse Pinkman, to sell the meth he produces. Walt's scientific knowledge and dedication to quality lead him to produce crystal meth that is purer and more potent than any competitors'. To avoid the tedious collection of pseudoephedrine required for production, Walt devises an alternative chemical process utilizing methylamine, giving his product a distinctive blue color. His crystal meth, which is given the street name "Blue Sky," dominates the market, leading to confrontations with established drug makers and dealers.

Walt is initially squeamish about the use of violence, but gradually comes to see it as a necessity. He also comes to find his new status as a drug lord psychologically rewarding, leading him to become less and less reluctant to resort to criminal acts such as theft, extortion, money laundering, depraved indifference, and murder. Walt's descent, Macbeth-like, into the criminal underworld unearths immense levels of deeply repressed ambition, rage, resentment, vanity, and an increasing ruthlessness which alienates him from his family and colleagues.

Skyler White (née Lambert) (played by Anna Gunn) is Walter's wife. She has had several meager sources of income: writing short stories, selling items on eBay, working as a bookkeeper, and ultimately helping her husband launder money. Skyler and Walter have a son, Walter Jr., and an infant daughter, Holly. Skyler cares for Walter very much, but their marriage becomes increasingly strained due to his unexplained absences and bizarre behavior, ultimately leading to their separation. Later, once Walter reveals his operation, she aids him in laundering his funds. They buy the car wash where Walter had recently moonlighted. Although she helps Walter, she remains displeased with the situation overall. As Walter slowly becomes more of a "hardened criminal," her emotions of fear and worry for him become increasingly prevalent. When in the episode "Buried," Hank tells Skyler he is on to Walt, but needs her help to provide sufficient evidence to build a successful case, Skyler replies that she needs a lawyer and later tells Walt they should remain quiet.
