On American Dad!, super-macho CIA agent Stan Smith frequently gets his hopes up that he'll one day own a pony. He's deeply saddened when he's forced to refuse one from Francine's real parents.
"I would have named her 'Buttercup'..."
In the episode "Draculee Dracula" of Animaniacs, Wakko wears pink pajamas.
Binky Barnes in Arthur lives in fear that his night light and interest in fine arts and ballet will be discovered and trash his tough reputation. In a song about the library, his solo line is "I like books with pictures of lots of pretty flowers", causing everyone to stare at him, to which he quickly adds "...being crushed by a giant pterodactyl!"
General Iroh on Avatar: The Last Airbender. He enjoys activities like drinking tea, playing Pai Sho, or bathing in saunas, and tries to curb his nephew's hot temper. Nevertheless, he is one of the cast's best fighters. Also note that he serves and grew up in the Fire Nation, a Proud Warrior Race. The fact that he can do those things, and that no one except similarly powerful characters says a thing about it, proves his badassery.
Sokka, too. "I'm not the one whose purse matches my belt," Katara teases him, but that doesn't change the fact he's a Badass Normal.
Rhinox in Beast Wars believes you should always stop to smell the flowers. He also dual-wields chainguns; when sufficiently annoyed he can pick Dinobot up by the neck and shake him like a maraca until he stops carping; and, when forced into a Face–Heel Turn by Megatron in Season 1, proceeds to roflstomp his way to the top of the Predacon hierarchy in about 15 minutes.
On the subject of Beast Wars, Megatron's rubber ducky.
Cow and Chicken had an episode where Chicken, Flem and Earl summon Sgt. Weenie Arms, a hero one of their action figures is based on, so they can become "Weenie Marines". One night of Training from Hell later, they awaken to find that they have huge muscular bodies and manly stubble, and Sgt. Weenie Arms presents them with action figures worthy of Weenie Marines..."Pencilneck Cissy", a Barbie analogue. When they object, he tells them that real men aren't afraid to play with dolls.
Darkwing Duck, the Badass Normal hero of the series of the same name, wears a purple costume (the cape is pink on the inside). He's also a loving parent to his daughter, whom he raises together with his sidekick/Heterosexual Life Partner Launchpad McQuack.
Dave the Barbarian is a perfect example for this trope. He's huge, tough... and enjoys cooking, cleaning, and collecting cute nick-knacks, among other things. His love of nick-knacks in particular once helped save the day, when a Monster of the Week turned out to share his interest and they immediately bonded over it.
The big, hulking, muscular and gentle warrior Lian-Chu, from Dragon Hunters, is very fond of knitting, something that his best friend since childhood and dragon-hunting partner Gwizdo, a Lovable Rogue, often makes fun of. In the 2008 CGI prequel movie of the same name, Lian-Chu's knitting needles even play an important role in killing the World Eater.
In Western Animation/Detentionaire, Biffy counts. He likes playing with his cat, and knits sweaters for him er, her.
Doctor Dred from Drak Pack has pink gloves, a pink band around his hat, pink slacks visible under his greenish coat, and even has pink eyeshadow on.
in The Emperor's New Groove, Kronk, the tough-and-macho henchman to the evil Yzma, has a flair with gourmet cooking not seen since Julia Childs.
Jorgen von Strangle from The Fairly OddParents. He kicked a whole negative universe's worth of Fairy ass and was a five-stars officer in the fairy military. His hobbies? Baking delicate pastries and watching mushy soap operas. Not to mention he married the Tooth Fairy and a whole episode is dedicated to him being broken-hearted after she temporarily dumped him.
Timmy Turner's shirt and hat are pink. This was because, in the episode "The Secret Origin of Denzel Crocker", Mr. and Mrs. Turner were expecting a girl, and thus they bought girl-related stuff, like girls' toys and clothes.
At the end of "The Boy Who Would Be Queen", where after spending a whole day as a female, Timmy decides to give himself a treat and goes to the local beauty salon. The ladies who work there are so delighted that they even wish he'd date their daughters. And in the beginning of the episode, he was shown enjoying soap operas.
Francis is decked out in bully attire, but if his name weren't a hint to this trope, his room is also wallpapered with posters of pink unicorns.
Dark Laser, a very powerful Captain Ersatz of Darth Vader and master of dark powers, is extremely concerned with the interior design of the Death Ball, insisting it be "cozy".
An example of the trope's name, Manly McDiverman, a pink diver decoration named by Cosmo in the episode featuring Greek Gods and Goddesses.
Fillmore! is a badbutt boy who is always solving crimes with his best friend Ingrid. The mug he is often seen drinking hot chocolate from is purple with a pink bunny on it.
He has many straight up examples: his earnest enjoyment of the robo soap opera All My Circuits, his "pregnancy" with beer, his number two most repeated word is "Daffodil", he has a deep love of cooking (and his hurt reaction when it sucks), is obsessed (and stalked) the aforementioned soap-opera's star, and the TIME HE ALMOST MARRIED SAID STAR. And displayed some emotional aftermath at episode's end.
How much of his girlfriend's (the Planet Express Ship. Yes, he dated a ship. He likes a girl with a nice, 400 ton booty) personality stuck with him?
Bender: Bender is a lone wolf, a solitary eagle, a cuddly baby tapir, and that's the way I like him.
Goof Troop: One of Goofy's friends is a huge and muscular man who works as a waiter. Pete commented that a man must be huge to wear an apron without a problem. The man secretly leads a double life as an undefeated wrestler. He'd rather quit but can't unless he loses and won't throw a fight.
There is also Pete himself, who wears light purple pajamas and bunny slippers. One episode also had him eyeing a luxury sports car that was colored Cherry Pink.
In Hey Arnold!, Helga's father, Big Bob, is big. And when he throws his back out and can't work, he is shown becoming addicted to watching soap operas (and demanding his wife videotape them when he goes back to work).
Inspector Gadget has no problem cooking for his niece while wearing a pink frilly apron over his trenchcoat.
Mrs. Buttowski: Oh, how cute, Gunther! You're a darling little ballerina! Gunther: Actually, Mrs. Buttowski, I'm famed Viking warrior Thor Thorson. He was so fierce in battle, he wore purple tights to avoid intimidating his own men.
Ron Stoppable of Kim Possible plays into this territory. Sure, as Kim's sidekick and master of Mystical Monkey Powers he regularly saves the world, but he is also a dab hand at cookery, keeps a (pink!) naked mole rat as his pet, and is obsessed with trick-or-treating (the photo of him and Kim dressed up as a princess and a cowboy... respectively) and a certain Christmas animated special.
In the King of the Hill episode "The Sun Also Roses", the rose gardener Morgan treats the details-obsession and hyper-competitiveness of the rose hobby as a natural extension of his big-guy toughness. When his rose wins "Queen of show", he shouts "Who's the queen? You know it!".
Big Macintosh is a very large (Draft horse?) stallion who works on his family's farm, is incredibly strong and tireless even by Earth Pony standards, and is implied in several background events to be a Chick Magnet, but:
In the episode "Lesson Zero", Twilight Sparkle enchants her childhood plaything with a spell that causes everyone to want it for themselves. After the spell is dispelled, the doll is left on the ground, only for Big Macintosh to grab it and run off.
In "Brotherhooves Social" he shows absolutely no compunctions about wearing a frilly dress, wig, and makeup so that he can compete in the Sisterhooves Social with Apple Bloom.
Twilight Sparkle's elder brother Shining Armor. Another large stallion, Captain of the Royal Guard, born to protect others, doesn't hesitate to attack a massive Eldritch Abomination with little expectation of doing more than delay it. Sheds liquid pride when his sister is coronated, always cries at weddings and is generally quite sweet natured. He was also a proud nerd in his high school years.
Spike seems especially prone to this trope, what with his desire to attend the Grand Galloping Gala in "The Ticket Master", wearing a pink apron in "Dragon Quest" and even playing with pony dolls in "A Canterlot Wedding".
Buford's love for his goldfish in Phineas and Ferb. He also plays the violin, the piccolo, and the accordion, speaks fluent French, and quotesVoltaire.
Let's not forget Agent P, who has been seen watching mushy soap operas on his days off.
Mojo Jojo from The Powerpuff Girls, an evil, ruthless, scheming, diabolical villain whose main goal is to Take Over the World, shows a hidden cooking talent when forced to babysit the girls (the girls didn't like it, but it's implied this was them being bratty rather than him a Lethal Chef). The Grand Finale plays it straighter with him, when we discover that his whole reason for wanting to rule the world was to make it a more peaceful place. "Free puppies for everyone!" indeed. (Though that line was originally said by Bubbles, Mojo was the one who actually enforced the law.) Though again subverted when he gets bored with the peaceful world and reverts to his life of crime.
Also, HIM is the ultimate example of this. An effeminate Satan who's described as the ultimate evil, a villain so terribly diabolical that not even his name can be said... who does yoga and owns a breakfast café, among other things. He's also the biggest threat out of all the villains the girls face.
In Scooby-Doo and the Alien Invaders, one of the suspects is a large, muscular Native American who refuses to explain why he is mysteriously roaming the roads at night. It turns out that his hobby is collecting pressed flowers.
Nelson in The Simpsons forced Bart to detour from their trip to Knoxville, Tennessee so he can see an Andy Williams concert in Branson, Missouri (or as Homer calls it, "Vegas, if it were run by Ned Flanders.")
In another episode, he's seen earnestly explaining to his classmates the proper way to clean, and apply powdered sugar to, freshly-picked huckleberries. When Principal Skinner wanders within earshot, Nelson quickly ad-libs something about punching a kid in the face.
In yet another episode, one of his prized possessions is seen to be a photo from Disneyland of a girl dressed as Snow White. When a shady private eye tells him she's just an actress, Nelson snaps "Shut up! Some of us prefer illusion to despair!"
In "Lisa On Ice", he's doing bad in history, geography, and math, but doing surprisingly well in Home Ec. He tells Skinner to keep it quiet.
Jimbo also these moments. In the Season 6 episode "The PTA Disbands!" (in which the teachers of Springfield Elementary go on strike), Jimbo is seen in a fancy living room watching soap operas with his mom ("I haven't cried this much since The Joy Luck Club!")
And of course, there was Dolph, Jimbo, and Kearney's reactions to Bart's ballet performance in "Homer vs. Patty and Selma" and their mock therapy session in "Whacking Day".
Jimbo: Bart does ballet! Kearney: He dances like girls! Nelson: Ha ha! Bart: Go ahead and laugh, but I took a chance and did something I wanted to do, and if that makes me a sissy, well I guess I'm a sissy! (Beat) Jimbo: ... he's a sissy! Let's get him!
The three bullies were also moved by Ralph Wiggum's surprisingly emotional acting as George Washington during the President's Day parade. Jimbo says his performance made him interested in learning more about the founding fathers and Kearney enthusiastically shouts "To the library!"
The first episode of Season 3 has Homer wearing one thanks to Bart placing his lucky red cap with the white laundry. Of course, this gives him trouble since wearing a pink shirt leads to him being sent to a mental institution.
Brock Samson, of The Venture Bros., is a hulking secret agent/berserker, who displays great concern for his herb garden and shares coupons with Doc Venture. Not only that but he seems to enjoy poetry, as evidenced by one of his conversations with H.E.L.P.eR.
