I feel like out of all of them, Hyde was actually the most patient with Fez. He definitely had a deeper friendship with Eric, probably was closer with Donna and he loved Jackie in a different way. But he didn't seem to get annoyed with Fez much like he did with the others and was maybe the nicest to him in the beginning. I think we should give him more credit for that since he really helped him out (and Fez said he was his role model)
In seasons 1 and 2, Hyde takes Fez โunder his wingโ to help him navigate life in Wisconsin (and American) teen culture. Even without the flashback inย โClass Pictureโ (4x20)ย where Hyde pledges Fez his protection, that pledge is evident.
Hyde generally, though not always, treats Fez as a person, not defined by the F in Fezโs name (i.e. foreign); unlike Kelso and Jackie, who variously point out and use Fezโs โforeignnessโ to their advantage and/or as a weapon against.
Though once (that I can remember), Hyde, too, takes advantage of Fezโs naivety / lack of knowledge due to his not being born and raised in America. In โEric Gets Suspendedโ (2x09). Hyde and Fez go on a blind double-date, and the following exchange happens when they first see their dates.
HYDE: Oh, theyโre hot! The blonde is blond ... and hot!
FEZ: Yes, and since I set us up on this date, sheโs mine, right?
HYDE: Well, I can see why youโd think that; but actually, since I came along to help you out, American custom dictates that I get the blonde.
FEZ: Once again, the local custom bones the foreign guy.
HYDE: America man! Love it or leave it.
Also, in โJackie Says Cheeseโ (4x13), Hyde enjoys burning Fez about how the new foreign exchange student, Thomas, is succeeding with women where Fez fails. In the end, though, Hyde shows his solidarity to Fez by joining in his scheme to rid himself of Thomas by stranding him in Michigan.
Except for those examples,Hyde is shown to be a good friend to Fez during seasons 1-5. In season 6, though, the focus in writing switches from characterization to jokes. All the characters suffer because of it and act in conflict to previously and concretely established characterization. In Christmas (6x07), for instance, Hydeย sets Fez up to get attacked by Point Place High jocks. This stands in sharp contrast to Hydeโs offer of protection to Fez in โClass Pictureโ.
Hyde: Look man, if those jocks try to do this to you again, just come find me.
It also contrasts with Hyde (and Eric) avenging Fez after Fort Anderson students attack Fez for his loyalty to the Point Place High Vikings.
In โSubstituteโ (6x19), Hyde expresses his annoyance at Fezโs wish for a more intimate friendship.
FEZ: [Kelso and Mitch] look happy. Why don't we have a game?
HYDE: Would you stop asking me why don't we have stuff? "Why don't we have a song?" "Why don't we have a movie?" We're men.
FEZ: I thought we were sensitive men.
HYDE: We're not.
FEZ: One of us is.
HYDE: Shut up!
FEZ: And it's not you.
This was written more for the joke than characterization, but it characterizes both Hyde and Fez nonetheless.
Regardless, Hydeโs respect toward Fez is the most consistent and the most evident among all their friends throughout the series. The depiction of their friendship wanes as Fezโs friendship with Kelso ascends, but Kelso and Fezโs friendship need a meta of its own to analyze.
