"Better Call Saul" inhabits the same sad Albuquerque underground as "Breaking Bad," so it's natural that characters in the AMC shows would overlap. Ready to see how? (Spoiler warning: This gallery contains lots of details about both shows.)
Jimmy McGill/Saul Goodman (Bob Odenkirk)
He's the main character in the new series, so of course we need to include Slippin' Jimmy. Goodman appeared in 43 of 62 "Breaking Bad" episodes as Walt and Jesse's criminal lawyer, with an emphasis on "criminal." Thus far through "Better Call Saul," he's still just James M. McGill, Esq., but we're getting to that whole alter-ego thing, trust us.
In flash-forwards, we see that Jimmy/Saul lives long enough to become a paranoid, balding Cinnabon worker. Free icing? Could be worse.
Don Hector Salamanca (Mark Margolis)
He walks! Hector -- the uncle of Tuco Salamanca -- had a wheelchair in "Breaking Bad." But the old man who was constantly ringing his bell to communicate was a real crimelord in his younger, more virile days, which "Better Call Saul" shows.
In "Breaking Bad," Hector takes out Gustavo Fring (pictured) with a crazy suicide bomb, avenging the deaths of his OTHER nephews. We'll get to those guys soon.
Ken (Kyle Bornheimer)
Here's one of those deep pulls that we alluded to earlier. In "Breaking Bad," obnoxious Ken inadvertently helped Walter White break bad, and his mode of transportation suffered the consequences.
First, Ken stole Walt's parking space at a bank, while bragging on his bluetooth. Later, the loudmouth continued his boastful, irritating behavior. So Walt blew up his car, as chemists do.
In Season 2 of "Saul," Jimmy and Kim trick Ken into buying them a ton of expensive tequila shots at a swanky bar. The stock broker with "KEN WINS" on his BMW license plates tends to lose a lot in this universe.
Tuco Salamanca (Raymond Cruz)
Tuco's surprise appearance in Season 1 of "Better Call Saul" set the tone for even more exciting, unspoiled villainous returns. And then legs got broken, badly, because Tuco is a complete madmen.
Currently, Tuco is doing prison time, thanks to Mike. But he'll be out soon enough ...
In "Breaking Bad," the ruthless Tuco had worked his way all the way up to drug kingpin level. He, Walt and Jesse had some rough and tumble meetings before Tuco himself met his demise with a Hank Shrader bullet through the brain.
Mike Ehrmantraut (Jonathan Banks)
OK, OK, we know -- another obvious one. But you can't make this an all-encompassing list sans Mike.
Mike and Jimmy/Saul work together in both series, though their relationship remains rocky at best. Early on in "Better Call Saul," the two meet at a local courthouse, where Jimmy is a public defender and Mike works the parking lot.
Leonel Salamanca (Daniel Moncada) - One of the killer "cousins," who are really twin brothers. (They're cousins of Tuco's, and nephews of Hector's.)
The boys are dangerous, bloody, all-business hitman for the Juarez drug cartel. They're sharp dressers and have ever sharper axes. Both brothers get snuffed out as a result of a classic Hank firefight during "Breaking Bad," though this one lives long enough for one last-gasp badass hospital moment.
Marco Salamanca (Luis Moncada) - Click back to brother Leonel's slide -- don't they look similar?
One difference: How they died. Marco got the top of his head blown off by Hank in that classic parking lot fight scene. Gross, but fully earned.
Domingo "Krazy-8" Molina (Max Arciniega) - This was a really cool cameo. A more grown-up Krazy-8 was actually the first person Walter killed in "Breaking Bad," though he hemmed and hawed over it for a while, almost freeing his violent prisoner.
In "Saul," Molina comes across quite convincingly as a younger, more innocent version of himself, still new to the drug game and working at his dad's store. In a half-decade or so, he'll be choked to death with a bicycle lock in Jesse's aunt's basement.
Lawson (Jim Beaver)
Everyone's favorite weapons dealer sells Walt the gun he uses to mow down a whole lotta neo-Nazis. He also turned up on "Better Call Saul" to offer several rifles to Mike... though, to Lawson's surprise, Mike took a pass.
Honestly? We're most worried about people who turn up on "Better Call Saul" but not "Breaking Bad." Does that mean they went straight and avoided grim "Breaking Bad" fates? Or that they didn't survive "Better Call Saul"? Kim Wexler, let us know you're okay.
