Character biography
Unbeknownst to Walt and Jesse, Krazy-8 is a DEA informant, who acquires the customers of the dealers he rats out.

Season One
Krazy-8 becomes suspicious of Jesse when Jesse attempts to sell him a new product after Emilio's arrest, and Krazy-8 forces Jesse to take him to Jesse's new partner. Krazy-8 suspects Walt is involved with law enforcement and appears intent on killing him until Walt offers to teach Krazy-8 his drug formula. While mixing chemicals, Walt creates a small explosion that produces phosphine gas and appears to kill both Emilio and Krazy-8. Emilio dies, but Krazy-8 eventually regains consciousness, prompting Jesse and Walt to imprison him in Jesse's basement for several days as Walt works up the courage to kill him. Walt attempts to rationalize freeing Krazy-8, who has regained his health, but eventually strangles him with a bike lock upon realizing Krazy-8 plans to attack him with a concealed piece of a broken plate. Later in the episode, it is implied that Walter disposed of Krazy-8's body with hydrofluoric acid in the same manner as Emilio's. Throughout the series, Walt continues to make sandwiches without bread crusts, adopting the manner in which Krazy-8 ate sandwiches.
