Tig Trager (played by Kim Coates) appeared in a couple of scenes in which he and Marcus Alvarez (Emilio Rivera) tried to bring the war between the Mayans and the Sons of Anarchy to an end.

The FX show, which streams on Hulu, has featured numerous Sons of Anarchy characters and SAMCRO members across its four seasons, with actors like Robert Patrick, Katey Sagal and Tommy Flanagan appearing on both series.

Here’s who has made an appearance on Mayans M.C. so far:

Chucky Marstein (played by Michael Ornstein)

Introduced early in Sons of Anarchy as Otto’s (Kurt Sutter) compulsive masturbating prison buddy (the one who got his fingers cut off by the Triad), Chucky was introduced as the Mayans’ bookkeeper in the show’s first season.

Marcus Alvarez (Emilio Rivera)

It was not much of a surprise that Marcus showed up in Mayans M.C.—after all, he is the Oakland chapter president of the motorcycle club in the original FX series.

Lincoln Potter (Ray McKinnon)

Assistant U.S Attorney Lincoln Potter was a major thorn in the side of SAMCRO thanks to his attempts to bring them down with a RICO case. By the events of Mayans M.C., he has refocused his attention on the Mayans, the Galindo cartel and Los Olvidados.

Happy Lowman (David Labrava)

Mayans M.C. has given the mostly silent SAMCRO member a bigger backstory for Happy. In the spin-off, it was revealed that he was the one who killed EZ (JD Pardo) and Angel’s (Clayton Cardenas) mother.

Filip “Chibs” Telford (Tommy Flanagan)

At the end of Sons of Anarchy, Chibs was named SAMCRO president. So it was perhaps inevitable that he would return in Mayans MC. In the spin-off, he appeared in Season 2, when he attempted to make a gun deal with the Mayans that led to them going to war instead.

Rane Quinn (Rusty Coones)

Former Nomad president Rane Quinn appeared alongside Chibs on the show, after being presented as a background character through much of Sons.

Allesandro Montez (Jacob Vargas)

Allesandro joined SAMCRO from the Nevada chapter following the multiple deaths of Sons of Anarchy Season 6. By the events of Mayans M.C., he had been promoted to road captain, and also appeared as part of the Chibs gun deal storyline. In the Season 4 finale, it was revealed that it was the discovery of his body that led to the Sons/Mayans war.

Gemma Teller Morrow (Katey Sagal)

Gemma may have died at the hands of Jax (Charlie Hunnam) in the original show, but the spin-off managed to find a way to bring her back. The Married with Children star appeared in a flashback where she met EZ in prison.

Oscar “El Oso” Ramos (Ivo Nandi)

Introduced as one of the Rey De Los Mayas in the final season of Sons of Anarchy, he left the club to join the Galindo Cartel – a role he held in Mayans M.C. until his death in Season 3.

Les Packer (Robert Patrick)

The Terminator 2 star played the San Bernardino chapter president in the first show. In the follow-up, it was revealed that he had a part to play in EZ’s mother’s murder, but by Season 3 it was revealed the character had terminal cancer.

Alexander “Tig” Trager (Kim Coates)

Tig ended Sons by being named the vice president of Charming chapter of the Sons of Anarchy. As such, he was in a position to negotiate with the Mayans in the Season 4 finale to come to a ceasefire.

Mayans M.C. Seasons 1 to 4 are streaming now on FX.
