- Main article: Fez's Homeland
One of the shows running gags is that no one knows what country Fez is from. Fez is merely the phonetic version of the acronym FES: Foreign Exchange Student. His friends know his true name (the audience does not because when he says his name the high school bell is ringing), It is very long and he says the first five K's are silent. His friends say they are not going to remember it, as seen in a flashback episode so they decide to call him Fes(z) but Kelso suggested that they call him "Captain Poo-Face". What Valderrama was actually saying was the first names of the main actors who appear in the show. It was rumored that his mother and his true native homeland would be revealed in the series finale, but all were proved false.
He once said he had Latin pride, which led Red to believe he was Latin. Fez retorted "No, only my pride is". He once said that he could speak Dutch in a job interview, and viewed this as "his strongest point". Also, Fez once claimed his country has never fought a war. In another episode, however, he alludes to the fact that his country "won the war" against Britain. In Stolen Car he referred to his country as "The beautiful island of-" but was interrupted. The last two indicate that he may be Indonesian. In another episode he tells the gang that his ancestors were not Mayan. Fez refuses to ever mention what country he is from.
Another running gag for Fez in the show is his accent and slight lisp. Fez also tries to constantly pick up women flirting constantly with Donna, Jackie and even Laurie on a regular basis and he fails miserably every time. Fez's hormones and pervert like instincts always get the better of him and he resort to hiding in a closet like a pervert watching Donna and Eric having sex and has been caught on at least two occasions.
Eric and Fez are pretty good friends, playing burns on each other, playfighting like the rest of the guys do, and complimenting each other friendly. Eric is especially helpful in keeping the peace following Red's heart attack over Laurie & Fez's marrying, to help Fez not get deported.
Kitty Forman is basically the mother Fez never had. Very supportive, nurturing, smothering, and kind to him, Fez and Kitty have a very tight-knit relationship. Fez loves Kitty's upbeat and strong personality along with her protection of him while Kitty loves Fez's innocence, independence, happy go lucky, sensitive, and somewhat intellectual personality.
Their relationship does take a bump in the road however towards the end of the series where Fez shouts to Kitty "You're not my mother!", exclaiming displeasure and disobedience in Kitty's demand for Fez to stop having one night stands. Kitty was very upset and disappointed over the whole ordeal and reminisced over their best moments as she was quiet for a while, which was unusual, especially for Red. Fez later apologised and the duo rekindled with open arms.
Hyde and Fez start out by sharing the commonality of being more aware of how to romance girls than Eric and Kelso, while also being the competition to the latter two guys respective girlfriends, Donna and Jackie. Especially around Kelso, Fez and Hyde always share knowing looks and appreciate each other's burns where Kelso is oblivious. They also take to defend each other to the group or protect each other, such as when Eric and Donna post break-up fight over rights to the gang and Fez gets caught in the crossfire, or Fez attacking Kelso when the latter flushes their 'bag' stating that Kelso broke Hyde. Fez is also arguably the only guy not scared of standing up to Hyde and speaking his truth in the face of Hyde's potential retribution. However, this is one of Fez's common traits.
The two start out as rivals for Jackie's affections, although she isn't ready to admit that she'd rather be with Fez until years later. Where Kelso is a complete schmuck when it comes to Jackie, and also cheats on her, Fez is suave, a great dancer and a romantic. Fez also tells Kelso straight up what he thinks of him and the two eventually bond over not being able to win Jackie (after Jackie and Kelso break up) and become close friends, although the two do have their moments, such as Kelso often looking down on Fez because he is a foreigner and Fez looking down on Kelso because of his ignorance. The friends have a secret somewhat man crush on each other but will never act on it.
Another short relationship he had was with a girl from school named Caroline, whom Donna had set up with Fez. They shared a few love-filled months together until Fez realised that Caroline was obsessed with him and also mentally unstable. He broke up with her, lying that he and Donna were in love so as not to make Caroline think he ended the relationship because she was crazy.
Jackie brings Rhonda to the party to find Hyde a girlfriend, and she and Fez hit it off almost immediately, Rhonda telling Fez "I may not be pretty but, given the chance, I'll put out something fierce". Fez was romantically involved with Rhonda for awhile, and almost lost his virginity to her but she dumped him because of his perverse advances.
Eventually, Fez got a job at the DMV where he seduced his coworker Nina.
Fez was happy to show his friends he had a beautiful girlfriend. He was disgusted by her bigoted parents and wanted nothing to do with her afterwards. However, Nina cut up to him and begged him to give her a second chance by having sex in the bed of her parents as revenge, finally ending Fez's agonizing life as a virgin. But, as Fez recounted, it was not a magical moment; there was no soft music "like in the movies so I had to hum" - Nina had asked Fez to stop humming but he started again without realizing it. There were then some sounds that "were certainly not applause". The night ended with him sneaking out of Nina's bathroom window pantsless. Nina did give Fez a second chance by saying that they had to practice more and it appeared they got better.
However, the relationship did not work out and she dumped him for being needy.

Near the end of the Season 5, Fez was arrested for vandalism of the town's water tower and came close to being deported back to his native country. But at the last moment, Laurie Forman slept with Fez and subsequently married him so he could stay in America. Red suffered a heart attack upon learning this. Their marriage is clearly not one of love, as Laurie went on their honeymoon to Cancun with someone else.
In "Mother's Little Helper", Fez, working as the shampoo boy at a salon, meets a girl named Danielle, and they end up starting a relationship after Danielle stood-up her date (who turned out to be Kelso). When she kissed Kelso, Fez told her she had to choose between him or Kelso, to his surprise and joy, she chose Fez. Danielle explained to Fez and Michael that she chose Fez because she liked his assertive nature, something that further pleased him. They were supposedly still in a relationship after the episode ended, although she was never mentioned again.
In "Spread Your Wings", Fez had an interest in his co-worker Hillary. It was shown to be mutual though Hillary was put off by his perverted possessions that Jackie exposed but after that mess was cleared out they got together.
During "My Fairy King", Hillary and Fez are officially a couple and Fez calls her his girlfriend. It is shown that they have a good relationship and Hillary enjoys the sex with him.
In "Crazy Little Thing Called Love", Hillary surprises him by telling Fez of her decision to be a nun. Hillary had some regrets because she enjoyed her time with him.
- Main page: Fez and Jackie
In the first half of the series, Fez longingly pined for Jackie Burkhart, worshiping her like a queen (although he was often just as annoyed by her as the other gang). Jackie either failed to realize his love for her or did not act upon it because he was too weird . They did share a kiss in one episode when he mistakenly thought Jackie was opening up to him. They shared another kiss when pretending to be dating to help Jackie keep her job. Michael Kelso, Jackie's boyfriend, quickly socked him in the face. Jackie revealed to her friend Donna that she did enjoy his display of affection. Other times that Jackie has shown a small interest in Fez include the time when he wowed her with his dancing moves at a Disco and when he helped her win at a Roller Disco contest.
Jackie got drunk to celebrate her win and hit on Fez. After battling with his light and dark side (shown as two shrunken Fezs on each of his shoulders dressed as Batman and The Riddler), he decided to be a gentleman and not take advantage of her. The two did go on a date when Jackie broke up with Kelso, but Fez was let down when he realised that Jackie had not yet gotten over Kelso. He was also disgusted that she was engorging herself with food.
Towards the end of the series, she finally realizes her feelings for him and kisses him but he rejects her. Jackie later sought revenge after being hurt Fez turned her down because of his assumption that she only wanted him because he was "a third base" to Hyde and Kelso. After Jackie's revenge's destruction is done, Fez gets even by ruining her hair and reminding her of all her previous rejections to him and calls her an awful person for hurting her actions. After brief tensions, he realizes his error but is turned away with this failure, he tries to go back to his country. Though after she is persuaded by his friend, she comes to see she genuinely likes him and stops him from leaving. In the Season 8 episode before the finale, the two finally confessed their feelings and become boyfriend and girlfriend.
