- "You're not cut out for this line of work, Walter. You should get out, while you still can."
Domingo Gallardo Molina, better known as Krazy-8, was a meth distributor formerly associated with Jesse Pinkman and Tuco Salamanca. He is also the cousin of Emilio Koyama. He acted as the main antagonist for the first half of season one.
According to himself, he was born in Albuquerque. His father owns Tampico Furniture on Menaul. He worked in the store before quitting. Walt was a customer back then, and he speculated that he might have met Walt at that time. He has a degree in Business Administration from the University of New Mexico. He originally wanted to study music in Oberlin College or Berklee College, but his father persuaded him not to. He also has an uncle called Alex who wrote songs for the furniture store infomercial. ("...and the Bag's in the River"). While working at his father's store, Domingo also worked as a drug dealer for kingpin Tuco Salamanca and would make weekly cash deliveries to him, often wearing his Tampico uniform. After Tuco's arrest, he continued to work for Nacho Varga and Hector Salamanca, Tuco's uncle.
At some point however, Domingo left the employment of Nacho and established himself as a solo drug dealer and manufacturer and developed a tough reputation and took on the new name of "Krazy-8". In order to maintain a firm grip over the local drug trade, he would often blow the whistle on rival dealers to the DEA and steal their former customers for himself. He also met Jessie Pinkman at some point.
Better Call Saul
Krazy-8 appears in "Off Brand" delivering a cash payment to Nacho Varga with Hector Salamanca watching. The payment is light and Nacho lets him off easy, but Hector comments on this and Nacho then proceeds to savagely beat Krazy-8. He appears again, still injured, in "Slip" delivering another payment to Nacho who determines that Krazy-8 gave him the correct amount and lets him go. Nacho then pretends one of Krazy-8's bills are marked, buying him the chance to switch out Hector's pills with fakes as he intended.
When Jesse tried to sell Walt's new product to Krazy-8, he forced Jesse to take him to his new partner. When Emilio recognizes Walt from accompanying Hank on the drug bust, Krazy-8 furiously believes that Walt is involved with law enforcement and plans to kill him until Walt offered to teach him his meth formula.
Emilio and Krazy-8 follow Walt into the RV and force him to show them his recipe at gunpoint. While mixing chemicals, Walt created a small explosion that produces phosphine gas, choking and incapaciatating both Emilio and Krazy-8. Walt explains to Jesse -- who tripped and knocked himself unconscious before Krazy-8 and Emilio entered the RV -- that one whiff of phosphine gas is enough to kill ("Pilot").
Emilio died as a result of the phosphine gas, but Krazy-8 managed to survive, shocking both Walt and Jesse. After Krazy-8 unsuccessfully tried escaping from Jesse's house, Jesse and Walt imprisoned him in Jesse's basement by securing him to a pole with Jesse's bike lock. Walt and Jesse flipped a coin to decide who would kill Krazy-8. The coin flip determined that while Jesse would be in charge of "disincorporating" Emilio's body, Walt would be responsible for killing Krazy-8. However, Krazy-8 lived for several days as a prisoner while Walt worked up the courage to kill him ("Cat's in the Bag...").
Walt attempted to rationalize freeing Krazy-8, who had regained his health. Walt drank beer with Krazy-8 and gave him food and toilet paper before discovering, in Jesse's kitchen, that Krazy-8 has stolen a shard of a broken plate. Walt confronted Krazy-8 about the piece of broken plate, which prompted Krazy-8 to attack him with the shard. Walt strangled him to death with the bike lock ("...and the Bag's in the River"). It is then implied by Jesse that he was dissolved in hydrofluoric acid like his cousin Emilio.

- Jesse: "What do you mean? To, like, a distributor?"
- Walter: "Yes. Yes, that's what we need. We need a distributor now. Do you know anyone like that?"
- Jesse: "Yeah. I mean, I used to until you killed him."
