Lemongrab and his clone are all but outright stated to be a couple, complete with Headbutt of Love within seconds of meeting each other, and Bubblegum saying "I made him, for you to be with". Then "All Your Fault" goes into full Adam and Eve Plot, with the two starting a family together (and bickering with each other over what to name their children). However, they at least once refer to each other as "brother."
Everything about Abracadaniel is soft and delicate, his speech included, he uses rainbow magic, is outright repulsed at the idea of kissing Bubblegum in "Wizard Battle", gets very chummy with Ice King very quickly in "Play Date", and is shaped like a giant pink penis.
The Amazing World of Gumball: Leslie is an affeminate flower boy with pink petals. In a deleted scene of "The Saint", he is the only one out of the boys AND girls that liked being kissed by Darwin. In "The Upgrade", Bobert marries him with Alan, which also seemed to be happy despite having a girlfriend. In "The Mustache", Leslie gets impressed by Gumball's butt growing. According to "The Petals", he is also a drag queen. In one of the first episodes, "The Pressure", he hangs out with the girls at Molly's treehouse, and claims he, along with the girls also made up his boyfriend (though he never talked about his fake boyfriend earlier in the episode, unlike the other girls). He also is seen in the girls bathroom in "The Fight".
Parodied with the cartoons as superheroes Ace and Gary fight crime with an array of phallically-suggestive vehicles and gadgets while engaging in plenty of Ho Yay behavior, all the while their villains (except their Arch-EnemyMad Scientist Bighead) dance around the obviousness of their gay-ness.
On the commentary for the "Best of TV Funhouse" DVD, SNL writer Robert Smigel said "one of them is gay, and one of them is straight, which will lead to a breakup". He refused to say which was which.
American Dad!: Foster, who appeared in the episode "Lost In Space" and an alien, is the head of the royal guard for Emperor Zing. He falls under this because he wears a purple captains coat, wears yellow lipstick, and made a kissy face towards Jeff Fischer while in an elevator with him.
Arthur: Binky's Hidden Depths reveal an interest for stereotypically gay hobbies such as theater, dance (especially ballet), art, music, culture, and the likes.
Brandon Higsby. He is rather girly looking, is extremely hyper, is always neatly dressed and mentioned in one episode that he dreams about purple unicorns and he likes the color pink and teddy bear pencils.
Blake Gripling always seemed a little too obsessed with winning Carl's friendship and hates Carl's best friend Hoodsey.
Courtney, although very girly, gives off these vibes near-constantly, especially when interacting with Ginger. She is attracted to boys several times however is very close to Ginger, and to a similar extent Miranda. The fanon consensus is she's probably gay and either doesn't know it or represses it.
Avatar: The Last Airbender has Princess Azula. Even fans who don't like the interpretation of her character as a Psycho Lesbian won't deny that there is some basis for it in the show. She has several Les Yay heavy scenes with her friends, especially Ty Lee, to the degree where even her voice actress ships them. Her Villainous Breakdown begins after Mai and especially Ty Lee betray her, which could just as easily be seen in a platonic matter as it could a romantic. Azula did flirt with a guy in the Beach Episode, putting her into an Ambiguously Bi category, but even then it could be argued that she was more interested in the power than the actual boy.
Babar has Pompadour, an incredibly effeminate and sissy elephant with Louis XV-like attire, very proud of his wigs, obsessed with protocol and cleanness. And of course mangos!
In the Batman: The Animated Series episode "Feat of Clay", Matt Hagen (who becomes Clayface) has a partner and stand-in called Teddy Lupin, who shows some very ambiguous signs. At first glance they might just be good friends, but with Teddy grabbing Matt's arm out of joy, mothering and looking after him constantly, and saying things such as "we can go on!", plus Hagen's violent mood swings, it's hard not to interpret them as an abusive couple. Hagen, however, shows affection for a female character in a later episode "Mudslide", suggesting that he is either bisexual, or that the feeling was not mutual, or that there was no relationship whatsoever, or that he's happy with using and abusing anyone who happens to fall in love with him, regardless of gender.
Carmen Sandiego: Villains El Topo and Le Cheve. The two only work togeher and prioritize each other safety over the mission. Le Cheve in particular, calls El Topo "mon ami" (a French expression for both "my friend" and "my boyfriend"). In another moment, Dr. Bellum refers to El Topo as Le Cheve's "Dear Boy".
Eddie the Squirrel from CatDog seems to have an eye for Cliff.
Henrietta von Marzipan from Codename: Kids Next Door. She's introduced to the audience as a boy and subsequently has a lot of Foe Yay with Numbuh Five. In her last episode, she is returned to her true gender via the lifting of a curse, and finally makes up with Abby in a very sweet scene. She never gets a male romantic interest, either.
In the bannedDexter's Laboratory episode "Barbequor", the title character's sidekick The Silver Spooner (a Silver Surfer parody) was extremely effeminate and campy, including the limp wrist, he skipped when excited and raised one leg, walking on his tiptoes while swinging his hips, and slapping Monkey to prevent him from getting to his master.
The entire cast, especially in regards to the bizarrely perverted Captain Hero and Xandir P. Wifflebottom who stated "I'm on a never ending quest to save my girlfriend!" for the first three episodes, until he finally faces his sexuality and then changes that to, "I'm on a never ending quest to save my boyfriend!"
There's also Wooldoor Sockbat and Spanky Ham. When Captain Hero simulates sexual advances to Wooldoor, he swoons and says, "Captain Hero? I want you inside me." To which he responds, "Class dismiiiised." As for Spanky, he was right in the middle of a triple French kiss with Hero and Wooldor. Not so ironically, the ladies took "poker night" surprisingly well.
The episode where Xandir came out also featured other ambiguously gay characters such as Elmer Fudd and Snagglepuss.
Droids: The Adventures of R2-D2 and C-3PO: C-3PO became a gay icon shortly after his film debut, but the 1985 spinoff cartoon Droids takes the implications Up to Eleven. In addition to being mincing and prissy, Threepio has limp wrists, seems legitimately uncomfortable when a woman hugs him, harbors a fondness for fashion accessories, and shares a surprising amount of Ho Yay with R2-D2.
DuckTales (2017) introduces Storkules, a Greek Hunk, who is glad to see his best friend Donald Duck, who he is fond of hugging and patting. The fact that he also made a musclebound sculpture of Donald wearing nothing but a fig leaf that he looks lovingly at it is a bit of a tip off.
Apple White from Ever After High has a surprising amount of Les Yay despite being destined to marry Daring. She isn't dating Daring due to the belief that they will have forever to be together after high school and she also doesn't bat an eye towards his flirtatious nature towards other girls. Apple White leans towards this more than Ambiguously Bi, especially since Dragon Games has her being resuscitated by Darling's Kiss of Life instead of her brother Daring's kiss.
Cupid, such as in the "Wishology" trilogy where Cupid and Juandissimo had a scene in "The Exciting Middle Part" eating in an outdoor cafe together, acting very much like a dating couple (which would make Juandissimo Ambiguously Bi).
Chester doesn't like being too close to girls because he gets rashes and an episode had Chester cross-dressing and dancing with AJ when the two needed dance partners.
Franklin: Bear is very close and attached to Franklin, more than best friends usually are, and exclusively hangs out with Franklin for most of his time. He is tender, sensitive, effeminate, and doesn't have any interest in girls unlike Franklin. Bear dresses flamboyantly in a small and unbuttoned blue sleeveless vest. note Which is a gay cowboy stereotype and in Real Life, kids dont walk around and dress like that. (This is even more odd considering that the characters dont really need to wear clothes. Its definitely not going to keep him very warm anyways which means it could be a gaudy fashion statement.) Bear also likes to get very touchy-feely with Franklin and routinely tickles him, in odd positions.
President Richard Nixon's head has behaved very weirdly towards the headless body of Agnew and its clones, who are all vice presidents of Earth. When the first two incarnations of Agnew died, Nixon got enraged and behaved like a grieved and vengeful wife. He also appeared to be on a date with Zapp Brannigan in "The Thief Of Baghead".
Fry's not-actually grandfather, Enos is worth a mention. He's dating the woman who will become Fry's grandmother, but says things like "you ever get the feeling you're only going with girls 'cause you're supposed to" and when shown a pin-up calendar, he is more interested in the male pin-ups than the female ones. Unfortunately, he gets killed before we can ever find out.
George and Martha: Oscar & Wilde. Apparently in the short lived cartoon series, there is a pair of alligator characters who give off so many clear signs that there is definitely something more to their relationship. They live together, they go on vacation together, one is never seen without the other, and there's even a scene in one episode where the two are dressed up in outfits straight out of the Village People. The kicker? Their names are Oscar and Wilde.
Dade seems to really, really like the main character.
Dade: Don't get me wrong, Harvey. You know there's nothing I'd like more than to make a beautiful life with you, my friend. But I got a family down there and a life to live, and so do you.
Fee is the only one of Harvey's female friends who hasn't displayed interest in a boy. In "Nightclub Night", she is quite impressed by the club's female bouncer, so when Harvey tries to encourage her to talk to the bouncer, the whole discussion comes off like Harvey encouraging Fee to talk to someone she has a crush on.
He-Man and the Masters of the Universe (1983): Though looking back, the "ambiguously" was incredibly tenuous sometimes. (A running gag on Cracked is that whenever He-Man is brought up, they will inevitably mention that the show taught the children of the '80s that being gay is okay.) At best, Prince Adam was a Camp Straight who wore a pink vest and lilac pantyhose! When he became He-Man he basically stripped down to fur bikini briefs and a harness, with a magical spray-on tan! Years later, the parody cartoon VH1 ILL-ustrated, would do a spoof segment of Queer Eye For The Straight Guy where they show up on Eternia to makeover He-Man
Carson: Have five other gay guys already been here?
Stormer is the only major female not to have any male love interests, be it long term or a passing glance; the closest we get is her saying love is hard for her. Instead she has an episode with Kimber where she essentially plays the 'delinquent boyfriend' out of a 50s movie. The Les Yay is so thick it can't seem anything but intentional. Stormer even longingly looks at a picture of her and Kimber together (that she keeps by her bedside!) after their singing duo splits up. The 2015 IDW reboot outright made them a couple and few fans complained.
Rapture makes an off-hand comment early on that she and Riot are meant to be together, however that could be choked up as Characterization Marches On because Word of God also states that The Stingers feel no romantic feelings towards each other. Rapture is the only Stinger not to have a love interest at all.
Samy Garvin, who can best be described as Waylon Smithers in demon form. The fact that he has Always Camp dreams of stardom do not help his case. Word of God's remark though is "I dont think of him as either gay or straight, just someone with a pathetically desperate need to feel needed and more important that he is."
The eponymous Jimmy Two-Shoes as well. He has considerable Ho Yay towards Lucius and Beezy, shows no interest in girls beyond as friendsnote there were two Season 2 episodes in which he fell for a Girl of the Week, but fans consider both of those to be an Out-of-Character Moment, and in "Jimmy Matchmaker", when Lucius tells Beezy he needs a date for an upcoming event, Beezy turns to Jimmy and asks him how he looks in a dress. Jimmy responds with "Are we talking full-length or mini?", though he quickly adds "Nooooo way are you getting me into a dress'' when he realizes what Beezy means.
Johnny Bravo: Carl pounces on Johnny constantly (as in "Johnny Goes to Camp"), is very clingy despite Johnny shoving him away, all-too-into playing Johnny's pretend date ("Charm School Johnny") or wife ("Chain Gang Johnny"), is impervious to the wiles of chicks, often thinking they're evil ("Forest Chump"), and even said he loved Johnny while standing up for him against an angry mob in "Lodge Brother Johnny". Heck, the episode "Carl Be Not Proud" is practically nothing BUT Ho Yay.
Gil is mostly Oblivious to Love when it comes to Johnny's sisters but is very interested in Johnny himself. He expressed said that he loved Johnny after seeing Johnny cross dress and sell girl scout cookies and in another episode, he asks Johnny out on a date after being rescued by him from nightmare monsters, which Johnny accepts. What's odd about this is that he did express interest in some other girls including Jillian Vegan.
Dukey, his trademark laugh, some of the outfits he wears (particularly the vampire hunter episode) and getting cuddly with Johnny in the episode Johnny Irresistable to the point where he nearly starts humping Johnny's leg.
Zizrar the mole king and the mole people. Zizrar is flamboyant and dresses very camp while most of his minions dress in biker leather. Plus no female members of their species had onscreen appearances. What makes them ambiguous is that they never flirted with anyone.
Nobeard and his pirate crew. Their ship is colored pink and their flag has a skull with flowers on it. The crew dreams of using whatever treasure they find on kitchens, classical dance lessons, and theater plays and musicals. The crew also dresses very camp and many of them wear pink and purple. They also lightly slap their opponents rather than sword fight them.
The Legend of Korra: Wei Beifong (and possibly by extension his twin Wing) visibly flirts with Bolin when the latter rescues him from Kuvira. Given that there are confirmed LGBT characters in the show (i.e. Korra and Asami), the ambiguity here is quite justified, since there is a legitimate precedent.
Kulipari: An Army of Frogs: Gee does not have a canon love interest and did not show attraction to girls but he exhibited Ho Yay towards his best friend Darel, as he offered to give Darel a back scratch and Gee really enjoyed a massage that was given to him by a male Kulipari healer named Ponto.
Kung Fu Panda: The Paws of Destiny: Wing and Wong, the two warthog minions of Rooster. But the only reason it's "ambiguous" is because in the same episode (A Game of Fists) that they blatantly state that they're in love and a couple after Rooster brings up their lost wedding gift, Rooster later muddles it by saying he just made up the wedding to garner sympathy, with most people assuming that means he made up them being a couple too. But as the show goes on, the ambiguity starts to lessen as it becomes more likely that Rooster meant ONLY the wedding part, although they never undeniably mention their couple status again, just very very strongly hint at it. By the end of the series there's enough evidence that it's extremely likely that they really are a couple, but there's further ambiguity due to a line where Wong says that (s)he's with child, leading many people to believe that Wong is actually a girl. It is extremely unlikely that Wong is a woman due to multiple reasons that would take too long to list, but unfortunately cannot be 100% deconfirmed due to the fact that Wong and Wong alone is never referred to as any gender specific pronoun.
Legion of Super-Heroes has Color Kid, who wears a rainbow on his chest, as well as speaking and gesturing flamboyantly. He's also concerned at one point that he may not have used the precisely appropriate shade of green.
Marc Anciel has a fondness for Nathaniel, and his name sounds like the French word for "rainbow" (arc-en-ciel). The showrunners later confirmed him as gay.
Goth girl Juleka Couffaine has a ton of ambiguous moments with her best friend Rose, but nothing's been explicitly confirmed within the show itself, although the staff have heavily hinted that this is the case.
Vincent Aza, who behaves like a Stalker with a Crush toward Jagged Stone, and also dyed the tips of his hair pink.
Wayhem, who could be best described as Marinette's Spear Counterpart, right down to the obsession with Adrien. Wayhem takes it a step further by dressing very similarly to Adrien.
Lyra and Bon Bon are always seen together and sometimes act as if they are a romantic couple. The last few episodes of season nine drop the ambiguous part - they're shown proposing to each other in a Meaningful Background Event in "The Big Mac Question", and "The Last Problem" shows a photo of their wedding in the newspaper in a Freeze-Frame Bonus.
Stephen Magnet, the Sea Serpent from part 2 of the pilot. He's pinkish-purple, speaks in an effeminate voice, and cries when his fabulous mustache is ruined.
Gilda acts like a jealous girlfriend to Rainbow Dash in "Griffon the Brush Off", bordering on Psycho Ex-Girlfriend, but no romantic feelings are ever mentioned. Which only added to the already-rampant speculation about Rainbow Dash's tomboy personality and connection with rainbows (however, Dashie has some Ship Tease with male characters, nudging her into a slightly different trope).
Male bit characters tend to be modeled after flamboyant celebrities like Sigfried and Roy, Charles Nelson Reilly, and Andy Dick. Others that aren't explicitly based on celebs also often have effeminate voices and mannerisms, though there's usually a justification of being in an Always Camp industry like hairdressing or fashion.
One-shot character Rolling Thunder, who appears in "The Washouts", winks at a mare in the audience (who immediately faints) just before one stunt.
Applejack licked Glory in the beginning of the first special, though it seems like it's just affection and because she's covered in apple juice - it seems innocent until you notice some official figurines have Glory marrying Moondancer, another mare.
There's also Gusty, who fits for most of the same reason Dash does in G4 (plus she has an androgynous voice).
OK K.O.! Let's Be Heroes: Nick and Joff are heavily implied to be more than just friends, as they are not only often seen together, but they actually behave like a couple. In "Plaza Prom", they are each others' dates and can be seen dancing together in the end, while "Second First Date" show them together on a spot where it's implied to be a hot spot for couples on dates.
Vice-Principal Zeigler from Pelswick has a lot of stereotypical mannerisms, was just as excited if not more than the middle-school girls to see the boy band, N*Talented (whom all the other guys at least tried to hate), and occasionally dresses in a fairy costume. In one episode, Ace voices suspicions that Pelswick's online girlfriend might actually be a guy, and the hypothetical scenario involved the guy in question being him in the fairy costume. In another, Pelswick's grandmother refers to him as a "fruitcake."
King Julien. As mentioned in the film section, but is even more noticeable here, although he shows interest in courting the only main female character, Marlene the otter, and has also admitted to having girlfriends in Canada (no, really). Some of his dialogue can easily be interpreted as a ring-tailed lemur in serious denial. (Six words: "No one will be sucking seed!")
Mort might be a close second, though he's only interested in Julien's feet specifically, not the rest of him.
All the penguins have their moments, but those made the biggest deal of are Private and Rico - Private could be acting babyish, but it's just funny for the Dumb Muscle to have quite the number of notable 'gay' moments.
The Problem Solverz has Roba, the most sensitive member of the team and is frequently anxious about being loved and accepted. He practically had a man crush on master funny face artist Tony Marv, and becomes upset in another episode because he wouldn't be able to wear a salsa hat if Bad Cat went undefeated. Roba was also completely turned off by Katrina Rad's amorous advances (although she wascrazy), and is quick is criticize Alfe's fashion sense. His high-pitched voice and effeminate hand gestures are additional traits.
The Proud Family: Michael the "sissy" sole male cheerleader and son of the macho coach (who he can't call "Dad" in public).
Mikey from Recess is a deeply flamboyant, theatrically sensitive and emotional character who is hard not to read as this. It may run in his family in "Parents' Night" we see that his father is a small, equally effeminate man married to a large, masculine woman.
The Reluctant Dragon: In the Disney animated short, the title character is rather effeminate and very campy, singing in a high voice, reciting poetry, dancing on his tiptoes, doing the stereotypical gay wave, etc.
The title characters of The Ren & Stimpy Show, whose ever ambiguous status as a couple was something of a Running Gag throughout the series. When asked about fan rumors that they were a gay couple their creator reportedly just gave a Shrug of God and said "I don't know, it's none of my business". In the Adult Party Cartoon, however, it was made... quite explicit... that the duo were in fact lovers. This kind of ruined the joke, though.
Rick and Morty: Revolio "Gearhead" Clockberg Jr is heavily implied to be gay in the series. He speaks in an effeminate voice with an obvious lisp and displays several effeminate mannerisms, and he appears to own a gay magazine in his workshop on his home planet.
Sagwa, the Chinese Siamese Cat: Lik-Lik speaks in a effeminate voice and has speaking manners similar to the average Camp Gay stereotypes, and in addition he wears a hat and scarf while Hun-Hun is the only other alley cat who wears clothes.
Samurai Jack: Scaramouche, a robot assassin who was hired by Aku to kill Jack, has some signs of it. He frequently teased Jack in a flirtatious tone during his fight with him, often calling him "baby" and he also has several flamboyant mannerisms.
She-Ra and the Princesses of Power: While the show is normally extremely upfront about LGBT characters, there are Kyle and Rogelio. Kyle is the wimpy and talentless kid, while Rogelio is the buff Lizard Folk. Both are members of Adora and Catra's squad. They are implied to have something with each other, which is never clarified, aside from the fact that Rogelio is the only one to treat Kyle with any kindness and often save him from danger by carrying him out of it. In a tweet, a story board artist called them a "background ship", together with a compilation of images that has them close to each other in the background of various scenes. This wasn't helped by a lack of communication between artists and writers that resulted in Kyle saying no one in the Horde had ever been nice to him, despite Rogelio's protectiveness. This was cleared up after season 1, and both the artists and writers promised to make it more obvious.
Mr. Waylon Smithers used to be Ambiguously Gay but in later seasons the show just ran with the gay jokes. Originally he was strictly a "Burnsosexual", which eventually devolved into Ambiguously Gay and then just plain gay. He'd previously mentioned having a wife, but in a flashback their relationship was played out as a reference to Cat on a Hot Tin Roof, so...
Milhouse: A lot of jokes travel this route; Bart's Heroic BSoD after disastrous early school experiences (flashback episode "Lisa's Sax") lead to this exchange with a school counselor:
Dr. Pryor: Mr. and Mrs. Simpson, there's nothing to be alarmed about. Public school can be intimidating to a young child, particularly one with as many flamboyantly homosexual tendencies as your son. Marge: Bart's gay? Dr. Pryor: Ah, whoo, wrong file. (Counselor replaces file into its rack; audience sees the label: "van Houten, Milhouse").
In recent years, writers have played up this aspect of the effeminate and sissy nerd Martin Prince. In one episode, after fantasizing about becoming a basketball star, Martin imagines himself holding hands with a boy and a girl, though he only checks out the former. He is sometimes implied to have a crush on Nelson as well.
For that matter, Nelson himself, despite having dated Lisa, is sometimes shown as having a secret effeminate side of which he is very embarrassed of.
Skunk Fu!: Baboon is known to behave very effeminately at times, the hand gestures, the hip swings, the fact that he was willing to teach a monkey how to act like a girl and dressed up like one for Dragon's birthday, on the other hand he has been shown to have a crush on Fox the youngest shapely female character in the show.
Slugterra: Pronto Geronimole has a very effeminate attitude most of the time, has not been shown to have any interest in any girls throughout the whole series (or any of the movies), ogled a bejeweled purse at the mall, and when he crossdressed as a disguise his only complaint was that the shoes were too "Matchy-Matchy"
The Smurfs: Vanity Smurf is very effeminate, has the stereotypically affected voice of a "gay man", has a flower on his hat, is obsessed with his own beauty, and is always looking at himself in the mirror. Next to The Smurfette Principle and the alleged Communist propaganda, Vanity's sexuality is one of the most joked-about aspects of the franchise.
Eric Cartman and his obsession withKyleBroflovski. The subplot of the three-part-special Imaginationland consisted of Cartman trying to force Kyle into sucking his balls to humiliate him- to the point of traveling across the country, and even having the trilogy end with Cartman actually imagining him doing it, complete with calling him a 'dirty girl'. Additionally, Cartman states that girls are vile and disgusting (although he has shown attraction to girls regardless), had a relationship between Ben Affleck and his hand puppet of Jennifer Lopez, and he made-out with a cardboard cutout of Justin Timberlake while he was pretending to be Britney Spears. He performed oral sex on Butters, and made Butters reciprocate in a feeble attempt to right the first blowjob, which just lead to Butters being sent to a camp for gays.
Stan and his funny (as his mother puts it) relationship with Kyle makes Cartman look straight in comparison, though whether his girlfriend makes him this or Ambiguously Bi depends on how serious he actually viewed that relationship (it was never more than shallow, and it took years before Stan stopped vomiting uncontrollably around her). In "Two Guys Naked in a Hot Tub" Stan's parents try to get Stan to play with other kids while they're at a party, as Randy says to Stan that he has to make more friends. "You can't just spend all your time with Kyle, people might think you're... funny. "Trey said over 10 years ago that of any of the four main boys, Stan is the most likely to turn out to be canon gay, because he's the most sensitive. You can still see it.
Kyle himself might be of the Armoured Closet Gay variety; he's the only male of the main boys who expresses disgust at naked males, when the other male student characters seem fine with watching naked dudes, implying that he is unsecure about his own sexuality; furthermore, the only things he considers disgusting are suspiciously penis related (pee and bananas), while he doesn't have any problems with far less hygienic things like anthropomorphic sapient shits, further implying that he wants to make himself look straighter even though he has no need to.
Terrance & Phillip's situation is so ambiguous even they don't know what it is:
Terrance: That Scott really hates us. Phillip: Yes, perhaps he's homophobic. (Silence) Terrance: But we're not gay, Phillip. Phillip: We're not?
A running gag with Mr. Garrison for several seasons. He's virulently anti-gay, yet sports a stereotypical gay lisp. Several characters state outright that they thought he was gay, but he insists that he just acts that way to "get chicks". In one episode he writes erotic fiction and focuses on penises, seeming to get very aroused by his own writing, but then insists that he's just writing to what his audience, women, want to read. In later seasons he comes out of the closet but gets a sex change and while a girl, sleeps with a couple lesbians before eventually going back to being a guy.
Jimbo and Ned. They're unrelated, live together, evidently have hospital visitation rights worked out. And then, Jimbo can say "fag" without getting bleeped, which according to Mr(s). Garrison means that he is one. All the other guys at the bar are bleeped when they say fag. After an awkward silence, Mr(s). Garrison says "Well, we've certainly learned something about Jimbo today."
Butters. He has been shown crossdressing, he's feminine, innocent, submissive, polite, and fits The Twink status. While he has shown affection toward girls, it's mostly blocked by his naivety. Oh, and he's more than willing to share his "creamy goo" with all the boys.
Various hardline religious groups have made efforts to get Spongebob taken off the air for its perceived support of the so-called "gay agenda". Word of God has said that calling SpongeBob "gay" or "straight" doesn't make sense, since he's a sea sponge that reproduces asexually. Later official information mentions that Spongebob has a crush on Sandy, a girl. (Contrary to popular belief, it is entirely possible to have a crush on someone and still be asexual).
Master Cyclonis is veryinterested in the female Piper, who's a similar case herself. It starts in Episode 6 where she infiltrates the Storm Hawks and becomes close to Piper, to the point when she tried to kill her with a special crystal it fails because, in Piper's words, it can't hurt someone you consider a friend. Their later appearances have both of them throwing out almost flirty dialogue in the midst of battle with a bit of inappropriate touching here and there. And then there's the time she scraped some food off Piper's cheek and tasted it. Notable in that the closest relationship Cyclonis has with a man would be her dragon, The Dark Ace, and that relationship is strictly professional, if amicable.
Arygyn the Skeelur, in Episode 25, "The Lesson", Arygyn (voiced by Scott McNeil) appears to the Storm Hawks team to train them. He is rather flamboyant in his mannerisms and clothing style, and often makes comments about someone's lousy hairstyle or the need for more decorations on the Condor.
Summer Camp Island: Word of God is that Oscar's close relationship with his female best friend Hedgehog is platonic. In one episode, Oscar compliments Ghost by calling him a "babe".
The museum director of the Cornbury museum. He acts flamboyant and signs of a lisp are found in his voice. He also Screams Like a Little Girl during virus attacks.
The Incredibly Amazing Man wears a purple supersuit, does not pay attention to any of the women swooning over him, positively accepts Kevin's "sidekick proposal" and is very narcissistic.
Symbionic Titan: Todd the decorator of the student council from the episode "Under The Three Moons". He wears a pink shirt and tight pants. he's very flamboyant, speaks with a lisp, and skips when excited.
Time Squad has Larry 3000, especially in the second season. The first season did have its share of gay innuendo with Larry, but not as much as Season 2; it's like the writers knew the show was getting cancelled and they wanted to get as much as they could past the censors. The biggest example being "Ex Marks The Spot", an episode that was pure Ho Yay with Tuddrussel and even ended with the line that he would be "sleeping on the couch tonight"; the nightclub scene from "Day of the Larrys" is a close second.
Chef Hatchet displayed a lot of behavior that can be considered gay. His friendship with Chris is similar to that of an old married couple and he has frequently cross dressed on his own free will. He also showed some attraction to Justin, a contestant on the series who is Camp Straight.
Topher, a constestant on Pahkitew Island has a huge amount of hero worship towards Chris. It does look as if Topher wants to take over Chris' job as host of the series but he has behaved effeminatley and made some questionable comments towards Chris.
Chris, the host himself. He has never flirted with any women onscreen, yet he has a lot of Ho Yay with Chef. He even showed some affection towards Justin, calling him hot and nicknaming him "McGorgeousness" He is also implied to have slept with his male pet, mutated venus fly trap Larry in "All Stars" as an egg Larry was holding hatched and one of his offspring greatly resembled Chris, which makes Chris whistle innocently.
Blitzwing, or more precisely, one third of him. When he's in his "Random" persona he has a high-pitched giggly voice, enjoys flamboyant dancing, is "light on his oscillating servos" and on one occasion referred to a crane as "big, bold, and sassy" — before he realized that the crane was an inanimate object and not a fellow Transformer. Blitzwing's other two personas have not expressed any sexual preference, but he seems actively repulsed by Blackarachnia. However this may be more because of her technoorganic form rather than her female persona. Oddly, while his other two personas seem actively repulsed by Blackarachnia it is the Random persona who wanted to "express his feelings for her in song". Said song being The Itsy-Bitsy Spider.
Starscream, who, as well as being on occasion quite flamboyantly fabulous, made five clones meant to represent different aspects of his personality — one of which was distinctly female. Which part of his personality was she? The answer given was "guess".
Generation 1 Tracks is famously this. Fan constantly either joke or say that he's secretly gay despite the fact that Word of God says this isn't true (or at least wasn't intended).
Blades from Transformers: Rescue Bots. He's effeminate, gets along most with the one female on the main team, and gets flustered when around Bumblebee.
Tutenstein: Luxor the cat shows signs of this in the "Cleo's Catastrophe" episode where he thinks about dating Jake.
Ugly Americans: Twayne is deliberately written as an ambiguous homosexual (or at least bisexual, given his attraction to Callie) as a running joke. He embodies a number of stereotypes about gay men, such as watching Oprah, being a poor athlete, and is even shown wearing a dress as a child. Additionally, most, if not all of his close friends are women and he even belongs to an all-female social club called "The Girls Club".
Watership Down: Cowslip from the animated adaptation acts like an elderly gay gentleman. He gets very excited when Hazel says they have no does (female rabbits) with them; he also hates getting wet and often brushes his ears back like an effeminate man would do with his hair. He was possibly intended to be more "intellectual snob" than gay, but that's what the viewers saw there.
Carver is into fashion, especially shoes but also mostly all of it, and gets caught wearing and/or buying women's clothes repeatedly, claiming they're for his sister.
Tino comes from a broken family, dominated by his trying-hard-to-be-unorthodox mother, and also has a very submissive/dependant personality that hints at a back-burner relationship or fascination with the local bully rough trade (as hinted at in said bully's not-declined offer of "Take me to the concert, and I'll beat you up" when Tino found that he had an extra ticket for a local concert... Tino's response was "I'll think it over").
Dojo. He admires Master Fung a lot and gets super jealous when other dragons hang out with Fung. Its ambiguous though because his admiration of Master Fung seems to be a reference to Chinese lore about eastern dragons loving the elderly. Its heavily downplayed in "Showdown" but flanderized in "Chronicles".
The white suited henchman of Pandabubba. He screams like a girl when given a wedgie and his underwear is pink colored. One scene that was cut from the official episode he appeared in had him mention how much he liked flying with the black suited henchman.
Young Justice: Impulse. He has an incredibly close relationship with Blue Beetle that is practically subtext. He is one of the few characters in the show that is shown to have no romantic interest in any girl. On a mission to Bialya (where there's Queen Bee, who can brainwash anyone who is attracted women) he is one of the only boys to openly be a part of it. And Greg Weisman has stated that his sexuality is a spoiler.
