Martinez (full name in the comic book series: Caesar Ramón Martínez) is a recurring fictional character from the comic book series The Walking Dead and was portrayed by Jose Pablo Cantillo in the third and fourth seasons of the television show of the same name.

Martínez is introduced in the 27th issue of the comic book series in April 2006 as the loyal second-in-command to The Governor.

He is responsible for bringing Rick Grimes and two of his fellow survivors, Michonne and Glenn into Woodbury to be questioned and later tortured.

Martinez's backstory is told in The Walking Dead novels, The Rise of the Governor,[citation needed] and The Road to Woodbury.

[2] After assisting Rick's party in escaping, Martinez betrays them by sneaking out of the prison to go tell The Governor its location so that he may capture and kill everyone inside.

[4] In The Fall of the Governor, his zombified head is put down by Lilly Caul following the failed prison assault.

In the episode "Made to Suffer", Rick and his group come to Woodbury to rescue Glenn and Maggie, and Martinez helps fight them.

In the episode "Home", Martinez assists The Governor in his attack against the prison, firing at Rick to keep him pinned down.

In the episode "Live Bait", in a flashback set hours after the prison attack, a depressed Governor does not try to stop a walker from killing him, forcing Martinez to shoot it.

They explore inside and are attacked by walkers - including two that are just severed heads - and the Governor saves Martinez and Pete.

The next morning, brothers Pete and Mitch, who served as Martinez's top men, reveal that they found his remains in the pit, and assume that he fell in due to being drunk.

Club in his review of "Say the Word", describes the fight match between Merle and Martinez as a way to "blow off steam", commenting: "The night-fights are stupid and silly, but they at least offer some sense of victory over the dead, some way to normalize all that's happened.

"[6] TV critic Keven Skinner, in his review of "Arrow on the Doorpost", enjoyed the scene between Daryl and Martinez, which he called playing a game of "whose d*** is bigger", by one-upping each other via brutal zombie kills.

[7] Skinner called Martinez's baseball bat kills "some of the most brutal this season" and the accompanying special effects "fantastic".

[7] Skinner also found it funny that during the filming of the scene, actor Norman Reedus missed his zombie target and wound hitting the back of Cantillo's head twice with a rubber knife.
