- "I know you, Alvarez. I grew up on the same streets. I've seen hot headed dicks like you give every Latino a bad name. Well, the final score is this... You aren't getting out of Oz, not in three years, not in thirty, not ever. Oh, we'll still go through the procedure, but that's so each time your number comes up, I can see how much you've ripened. I'm going to watch you ripen until you rot."
- ―Luis Ruiz[src]
Character Summary Edit

Plot Summary Edit
Season 5 Edit
He is one of the parole board members present during Miguel Alvarez's hearing. After Alvarez delivers a speech about why he should be granted parole, Ruiz begins attacking Alvarez's character with an overview of Alvarez's activities in Oz including; his escape from Oz, his role in the Em City riot, cutting out Officer Rivera's eyes, and the killings of Carlo Ricardo and Jorge Vasquez. Alvarez responds by punching Ruiz in the face, then beating him up over the table.
Season 6 Edit
Tim McManus approaches Ruiz in an attempt to convince him to have a meeting with Alvarez, so that Alvarez can apologise for hitting him earlier. Ruiz tells McManus that he'd consider meeting with Alvarez. Later, during their meeting, Alvarez apologises for hitting Ruiz, and Ruiz reveals that he deliberately provoked Alvarez into hitting him because wanted to see if Alvarez could handle himself.
Ruiz then tells Alvarez that he is going to see to it that Alvarez is never granted parole because he believes Alvarez is giving Latinos a bad name. Alvarez confronts Ruiz, and Ruiz encourages him to hit him again, but Alvarez doesn't and instead leaves the meeting with Ruiz discouraged.
