Last appearance: "… And the Bag's in the River" (his remains, anyway) Cause of death: Chemical explosion, via Walt
No dead body caused Walt and Jesse as much trouble as Emilio's. The meth dealer and his cousin Krazy 8 held Walter hostage and ordered him to cook, but Walt whipped up something else: a lethal chemical cloud. Walt shut the men in the RV and escaped unscathed. Afterward, Walt tasked Jesse with disposing Emilio's body using acid and a plastic container. Jesse ignored Mr. White's instructions and dissolved the body in his bathtub, causing one of the grossest messes in Breaking Bad history.
Last episode: "… And the Bag's in the River" Cause of death: Strangled with a bike lock by Walter
Remember the days when Walt actually felt bad about killing another human being? It took him several days and a pros and cons list to make his decision about Krazy 8, who was tied up in Jesse's basement. Walt ultimately decided to spare the young man, and only killed him after realizing Krazy 8 intended to stab him with a broken shard of a plate.
Final appearance: "A No-Rough-Stuff-Type Deal" Cause of death: Beaten to death by Tuco
Poor No-Doze had the misfortune of running afoul of his boss, Tuco, who beat him to death for simply reminding Walt and Jesse whom they worked for. The uncalled-for violence made Walt question the wisdom of working with Tuco, ultimately leading him and Jesse to plot the man's death. Tuco had another take on the incident, yelling at his brutalized employee: "What's the matter with you? Can't take an ass-beating, bitch?!”
Last appearance: "Grilled" Cause of death: Shot in the head by Hank
Tuco's death was arguably the most significant in the series -- setting in motion the cousins' vendetta against Hank and giving us Walter's troubled relationship with Hector Salamanca. After kidnapping Walt and Jesse, who attempted to poison him with ricin, the three men struggled in the desert, with Walt uttering one of his early Heisenberg lines: "We tried to poison you because you're an insane, degenerate piece of filth, and you deserve to die." Hank ended up finishing the job by putting a bullet in Tuco's head. It was his first step toward PTSD. (Receiving Tuco's grill as a gift didn't help.)
Final appearance: "Peekaboo" Cause of death: Crushed by an ATM
Spooge, we hardly knew ye. Breaking Bad showed the nasty side of meth use by taking us inside Spooge's unhappy home, where he unwisely called his live-in lady friend a "skank" one too many times. She responds by tipping the ATM that he'd trying to crack onto his head. On the upside, Jesse called the cops, so the adorable little boy presumably went on to have a better life. Peekaboo, indeed.
Last appearance: "Negro y Azul" (except for a flashback) Cause of death: Decapitated by the cousins
Danny Trejo played the DEA informant with a penchant for ordering things from catalogs. Poor Tortuga ended up with his head on an explosives-packed tortoise (the cartel is apparently a fan of irony). Hank -- freshly transferred to El Paso -- witnesses it all and gets full-fledged PTSD afterward.
Last appearance: "Mandala" Cause of death: Shot by a young boy, later revealed to be Tomas Cantillo, the brother of Jesse's love interest
Things were going OK for Jesse and his small band of meth distributors, but after pushing into new territory, Combo became the victim of rival drug dealers' wrath. The men ordered a young boy to kill Combo. True to Breaking Bad's complex storytelling, the murder would cause a ripple effect felt seasons later.
Final appearance: "Phoenix" Cause of death: Choked on her own vomit
This was a biggie. For many Breaking Bad fans, Jane's death marked the moment when Walter became a man beyond redemption. Though he didn't cause her death, he didn't save her when he could have. In June, creator Vince Gilligan revealed that he and the writers originally conceived Walt as having a more active role in Jane's death, but after the network pushed back, they settled on what ultimately aired. In hindsight, Gilligan called it the right choice, saying that would have taken Walter's character too far too fast.
Final appearance: "ABQ" Cause of death: In-air collision
Grief-stricken over his daughter's death, air traffic controller Donald Margolis allows two planes to crash into each other through human error. An infamous pink bear landed in the White's pool, whose accusing eye Walt ended up keeping and taking to his new bachelor pad. Some fans have deemed the crash as too heavy-handed an indictment of Walt's actions. But love it or hate it, the move was a bold on Breaking Bad's part.
A Truckful of Immigrants
Final appearance: "No Mas" Cause of death: Shot and blown up by the cousins
Nine unlucky souls happened to hitch a ride in the same truck as Tuco's cousins and one talkative teenager, who complimented the cousins' boots -- only to realize the skull-adorned footwear indicated the cousins were cartel men. Tuco's cousins opened fire, killed the driver, and blew up the truck. They certainly knew how to make an entrance in America. The cold-hearted act was all the scarier for the audience in their knowledge that the cousins had their sights set on an unsuspecting Walter.
Final appearance: "One Minute" Cause of death: Shot in the head by Hank
Marco decided that offing Hank with an gun was too easy a death for the man who killed his beloved cousin Tuco. So he fetched an ax to finish the deed. Unfortunately for the infamous cartel member, this gave the gravely injured DEA agent time to get one final bullet in his gun and end Marco's New Mexico murder spree. His brother, Leonel, would survive the attack but was later poisoned in the hospital by Mike.
Final appearance: "I See You" Cause of death: Shot by Federales
And he thought they were friends. Juan Bolsa learned that Gus was one step ahead of him, orchestrating the killing of the cousins and getting Mexican Federales to put the heat on him and raid his compound. They had a shoot-first, ask-questions-later policy, apparently. Gus won the battle of wits, as usual.
Final appearance: "Full Measure" Cause of death: Shot by Jesse
Jesse proved his ultimate loyalty to Walt by murdering the (relatively) innocent chemist/meth cook Gale, who was enjoying an evening in his tastefully decorated apartment. Jesse would go on to deal with guilt and self-hatred for months to come, but Gale's death would buy Walt enough time to destroy Gus' empire.
Final appearance: "Box Cutter" Cause of death: Throat cut with a box cutter by Gus
In the scariest Gus moment ever, the drug kingpin entered the lab where Walt and Jesse awaited his judgment regarding Gale's murder. Without saying a word, he changed into lab clothing, walked over to Victor and sliced his throat with a box cutter. Why? That's up for debate. Perhaps it was because Victor failed to keep Walt in line and allowed Gale to die. Or perhaps, as Walter theorized to Jesse in season five, Victor might have been killed for taking liberties that weren't his to take -- namely, attempting to cook a batch of meth on his own without Gus' knowledge.
Final appearance: "Hermanos" Cause of death: Shot by Hector Salamanca
Gus Fring's backstory was revealed to include the tragic death of his business partner (and possible lover). Max was gunned down by Hector during a meeting with Don Eladio, with whom Max and Gus wanted to go into the meth business. The killing of Gus' Los Pollos Hermanos partner started a lifelong hatred between Gus and Hector, and proved that Gus once had someone he cared about.
Final appearance: "Salud" Cause of death: Poisoned by Gus
In perhaps Gus' most badass moment ever, he poisons Don Eladio and his capos at a meeting where Gus was to give in to the cartel's demands and give up Walter's meth recipe (and Jesse). Gus presented the Don with a poisoned bottle of tequila, drinking some of it himself (and later throwing it up in the bathroom). "Fill your pockets and leave in peace, or fight me and die!" Gus shouts at those who remain alive. It was a shocking moment and one of the few times we root for the cruel drug lord.
Final appearance: "Face Off" Cause of death: Blown up by Hector
Just when you think the show can't get any more insane … ding! BOOM! Walt's brilliant plan began with poisoning an innocent boy, continued with forging an unlikely alliance with Hector and culminated with the old man blowing up Gus with a bomb rigged to explode when he rang the bell on his wheelchair. Sure, Walter technically bombed a nursing home -- but we'll let this one slide. It was awesome.
Final appearance: "Dead Freight" Cause of death: Shot by Todd
It doesn't get any worse than this. Drew Sharp -- a young man with a penchant for dirt bikes and tarantulas -- had the misfortune of coming across Walt, Jesse, Mike and Todd after they successfully complete a methylamine train heist. Todd shot the kid so he wouldn't tell anyone what he'd seen. Jesse never got over the murder and eventually lost all respect for Walt, who continued to work with Todd after the killing.
Final appearance: "Say My Name" Cause of death: Shot by Walt
Mike was about to ride off into the sunset, but got into an argument with Walter about giving up the names of his men in prison. Mike also blamed Walt for Gus' death, saying they had a good thing going when Gus was in charge. "You, and your pride and your ego! You just had to be the man! If you’d known your place, we’d all be fine right now!" Mike shouted. Walt acted rashly, shooting Mike and later apologizing, saying he could have gotten the names from Lydia. Then, Mike's dying words: "Shut the f--- up and let me die in peace."
10 Prison Inmates
Final appearance: "Gliding Over All" Cause of death: Stabbed, choked and burned on Walt's orders
After securing the names of Mike's men in prison, Walter orchestrates their chilling two-minute murder -- designed to happen too quickly for authorities to stop it. The men were the final obstacle to Walt becoming a kingpin, and his grisly plan's success only reinforced his ever-growing ego.
