Negi: You certainly seem very happy, Tosaka-san. I've never seen you like this before. Tosaka:(holding an autographed picture of Jack Rakan) Damn right I am! What are you, stupid? To gladiators like me, he is a freakin' god, you know?! Like a Goddamn deity walking the earth!
Judai of Yu-Gi-Oh! GX started fanboying over Yugi when they met in the final episodes of GX. At that point he'd just beaten the embodiment of darkness and was one of the strongest forces in the universe, probably. Of course, in terms of the card game, Yugi is still a freaking legend. Of course, it helped that he and Yugi had met in the first episode, and Yugi had given him the Winged Kuriboh card.
Excel and Hyatt squee before agent Key, much to Il Palazzo's displeasure.
And of course there's Excel's (and later Elgala's) obsession with Il Palazzo, which goes well beyond platonic admiration. Hyatt on the other hand is too busy either dying or drugging herself up to squee over anyone.
One Piece:Major Sergeant Tashigi is pretty much fangirling on the inside over Zoro on this page. There's kind of a double-subversion going on, though. She immediately presumed he was a bad person upon finding out he was a pirate, but doesn't realize that Zoro is still a good guy, and is still all what she was squeeing over earlier and far, far more. To clarify a couple of key points: First, she thought Zoro was a bad guy even before finding out he was a pirate (because bounty hunters clearly are only slightly less reprehensible than pirates). Second, at that point in the story, she didn't know that the guy buying swords was Zoro. Yeah...
Whitebeard's allies are this. Including Jimbei, a hero of Fishmen Island, who, along side with Arlong, was a fanboy to Fisher Tiger.
Now even Luffy has one. Bartolomeo is an anti-social Troll and a massive fanboy of Luffy. He looked up to Luffy so much that after Marineford he went to sea himself, becoming an Ascended Fanboy and entered the tournament on Dressrosa to win the Mera Mera no Mi so he could give it to Luffy.
Subverted in Death Note. When Misa meets L, (giving Light the chance to get L's real name) at first he just stares at her thoughtfully and then, when he recognizes her, starts acting all fanboy-ish over the idol, drawing the attention of everyone around. It turns out that he was suspicious of Misa beforehand and everything was part of a plan to steal her cellphone, thwarting Light's attempts to get his name and at the same time raising his suspicions about Light.
In very early Sailor Moon, the very first Sailor to appear is "Sailor V". Usagi often acts as a V fangirl, even after becoming Sailor Moon. (In several episodes she's shown at an arcade playing the Sailor V video game!) Eventually V is revealed to be Sailor Venus, who joins the other Sailors, prompting a few star-struck moments before things settle down.
Mink of Dragon Half is always squeeing over idol(/dragon-slayer) Dick Saucer. At the end of the manga, Dick Saucer meets his idol, Ruath the Red Lightning, renowned dragon-slayer. And he discovers that A) Ruath retired to marry a dragon, and B) the dragon-girl he's been trying to kill the entire series is his idol's daughter. So since his idol did it, Dick ends up marrying Mink. Dick and Mink are still gushing over each other after 8 years of marriage.
Galaxy Fraulein Yuna: Kagurazaka Yuna is an epic Fangirl of the Masked Maiden Polylina... who's really played by one of her friends (and former enemy), Lia. (In the game where Polylina is introduced, this started out as a full-on crush, or at least sounded like one.)
Mirage (the upgraded form of Tidal Wave) squees over Galvatron, to the point of cheerleading with a pink heart visible on screen with him. This is the English dub; in the Japanese original, it was a running gag of him being outright Gay for Galvatron (with lines along the lines of "nobody loves Galvatron more than I do!"). Given this information, the fact that Tidal Wave was specifically modified to be able to powerlink with Galvatron (a process that involves an intermingling of sparks) becomes a bit more worrisome.
Ironhide began the series fanboying the veterans of Transformers Armada, especially Hot Shot. Later in the series, a trio of younger 'bots fanboy him.They become dead sidekicks three or so episodes later.
In Robotech/Genesis Climber Mospeada Scott/Stick Bernard has always admired Colonel Jonathan Wolfe/Major Jonathan ever since he was a kid. When Bernard finds his hero still alive on Earth and doing guerrilla warfare against the Invid, he becomes ecstatic, and he eagerly accepts the offer to join the Colonel/Major's team. Later however, Rand/Ray finds out that Jonathan has actually been selling his people out to the Invid; and when he tells Bernard about it, Scott/Stick slugs him for defaming his hero.
Princess Cornelia from Code Geass can go pretty much into Fangirl mode when you mention her idol, Empress Marianne.
Side materials suggest that Lelouch's Zero persona is inspired by a clandestine love of Tokusatsu; one of the History Lesson stories included in the DVD booklets has C.C. catch him humming a tune which she identifies as the theme song for a Toku series that aired around the time of the invasion of Japan.
In Tiger & Bunny, Wild Tiger/Kotetsu T. Kaburagi is a rather vocal fan of Sternbild's first superhero, Mr. Legend. Ends up on a Broken Pedestal when Kotetsu is told that once Legend's powers began to fade, the 'crimes' he foiled were actually set up by the TV show. One wonders what his reaction would be if he found out how bad Legend reallygot.
A villainous variant occurs in Fate/Zero; Uryuu, the demented serial killer, accidentally summons Caster, and soon goes into total fanboy mode when he discovers that Caster is even more enamored with disturbing violence than he is, and has various superpowers to assist in his creatively horrific mutilations. Justified, since Uryuu summoned Caster without a catalyst, so the ritual provided him with the spirit most suited to his personality.
Spidey: Plus it's, like, you're standing there and I'm nerding out on the inside. [...] Permission to freak out openly...?
And there's also another Captain America and Spider-Man Team Up, where it is very easy to believe that Spidey is not just squeeing at Cap, but crushing.
Spidey also regarded Batman like this (in a more dignified way) in the first Batman/Spider-Man inter-company crossover, calling him "a legend"; in fact, when Batman told him to leave Gotham and let him handle Joker and Carnage himself, Spidey was seriously considering doing so, only deciding to stay when Batman changed his mind.
Spidey has got this treatment himself a few times. Mattie Franklin (one of the Spider-Women) was a total Spidey fangirl.
Likewise, during a Time Travel story, the Post-Crisis Superman once shook FDR's hand, and got quite emotional, if only in his thought balloons.
In the same story, Superman sees Doctor Fate, Dr. Mid-Nite, The Spectre, and Jay Garrick through a skylight and spends about a page fanboying to himself and wondering if he'll really ruin the timeline that badly if he just pops in for a moment to meet them.
It's fairly common in DC crossovers for almost every character created after 1980 to have this reaction when they meet Superman.
The Pre CrisisLex Luthor felt this way about Albert Einstein. After all, this was Mad Scientist Lex, and Einstein had been his childhood hero. Luthor would commemorate Einstein's birthday each year by traveling to some pivotal location from Einstein's life for a visit (spending one day working in Einstein's old patent office, for instance). It took Superman years to figure out why Lex was behaving so oddly, until he made the connection, at which point he was genuinely touched. Notably, Lex couldn't bring himself to do anything genuinely wicked on that day, out of respect for his hero. Notably, this story was written by Elliot S! Maggin, who always treated Lex with more tragic sympathy than other writers did; and Einstein is Maggin's personal hero.
In Dark Reign: Young Avengers, upon meeting Norman Osborn superperson artist Coat-of-Arms has one of these moments. She (literally) lets out a "Squee!", then proceeds to go into super-fangirl mode, gushing about how she admires Norman's "works" while showing him paintings she did of some of his more infamous moments (including killing Gwen Stacey). This pisses Norman off and, for a brief moment, he loses his composure and flips out on her. The fact he "went into Green Goblin mode" makes her completely ecstatic.
Most of the Young Avengers are total fanboys or fangirls, especially Wiccan and Hulkling.
In Booster Gold, time travellers had got Sinestro to come to Earth ahead of schedule, so that he would meet Guy Gardner and cause disaster, by telling him that he would no longer be the greatest of the Green Lanterns. Booster had to stop him. After a brief attempt at fighting, Booster tries, "But I'm your greatest fan!" He gushes over him, tells him that he knows in his heart he can never be replaced, and convinces him that it was a plot by his enemies to find out what he feared. This meeting would go on to have a notable consequence: Sinestro asks Booster what Corps he belongs to, leading him to make up the name "Sinestro Corps" on the spot. This gets Sinestro thinking...
Victor Mancha of Runaways got really excited about meeting the X-Men. Strangely, he was much calmer about meeting Spider-Man, who he cited as his favorite superhero in his very first appearance.
Tim Drake (the third Robin) was more-or-less an ascended Batman fanboy. An amateur detective, he deduced the secret identities of Batman and the first Robin, Dick Grayson. Following Jason Todd (the second Robin)'s death, he forced Batman into making him Robin, believing that Batman needed a sidekick to keep him stable. A later issue of Birds of Prey showed that Tim was also a huge fan of (the second) Blue Beetle.
Similarly, Dick Grayson, the first Robin, first Nightwing, and second Batman, has been shown, both in and outside of current canon, to be a huge Superman fanboy, more outwardly so when he was still Robin.
To the point where he took the name Nightwing after a hero from Kryptonian legend.
Batman himself has never actually gushed upon meeting someone he admired, but his brief meetings with retired legends The Shadow and Sherlock Holmes (both of whom he claimed inspired his career) did seem to excite him a little.
Ironfist from Last Stand of the Wreckers, is a total fanboy of the titular Wreckers. The fact that he got to work with them was like a dream come true. It makes his death at the end all the more saddening.
Ladytron in WildC.A.T.s is a huge fan of Overt-Kill, the biggest and most powerful cyborg in the world. She's got the trading card, the posters, that punk song that sampled one of his one-liners, everything. One of the only reasons she even joined up with the team was because she was promised the chance to meet him. When she finally does, she frantically looks around for a piece of paper for him to sign. Of course, she also wants to fight and maybe kill him, because she's kinda loco like that.
In Archie Comics' Sonic the Hedgehog's "Mobius: X Years Later" continuity, Argyle, Vector the Crocodile's son, is a major fanboy of Sonic, squeeing madly when the Blue Blur spouted out his Catchphrase "Let's Do It To It!" when mobilizing the emerging Future Freedom Fighters.
In her micro comic, Pinkie Pie is a huge fan of Ponyacci, a famous Equestrian clown.
An odd recursive version of this occurs in "Earning Wings of a Different Nature", when Princess Luna saves Daring Do from a nightmare. For the latter, she's in the presence of one of the diarchs of their native world. For the former, however...
“As in, Princess Celestia and I,” Luna clarified, “My real name as a human was John Sappington, but you may address me as simply ‘Luna’ if you wish”.
“Mark,” Daring nodded weakly, “Mark Sheffield. Otherwise known as Daring Do, apparently”.
Luna coughed loudly to suppress a *squee* at the name ‘Daring Do’.

In Kung Fu Panda, Po is exploding with delight over getting to hang out with the Furious Five. The Five don't quite share his enthusiasm.
In the sequel Po is thrilled to be locked in the same pressure-point shackles as Tai Lung. Even noting this fact with a bit of audible glee.
In Ice Age: Dawn of the Dinosaurs, Crash and Eddie (and to a lesser extent, Diego) become obsessed with the Crazy Survivalist Buck.
Crash: You are Super Weasel! Eddie: Ultra Weasel! Diego: Diesel Weasel!
In Cars, Lightning McQueen goes Squee over Doc Hudson when he realizes he was a great race car in his day. Leading to the painful scene where none of Doc's friends will believe him, and Doc watches, knows he is telling the truth, and says nothing.
Films — Live-Action
In The Dark Knight Rises it's revealed that Jim Gordon isn't just Batman's friend and ally, from the moment in Batman Begins when Gordon tried to comfort Bruce Wayne when his parents died, Jim was Bruce's personal Hero.
Star Trek: First Contact, the second TNG film, has the crew traveling back to the mid 21st century and meeting Zefram Cochrane, the man who invented warp drive and pretty much founded the utopian principles of the Star Trek universe. Much of the crew expects to meet a living saint, and instead discover Cochrane to be a raging drunk who cares more about money than anything else. Other crewmen, like Riker, either didn't have such expectations or just got used to the reality faster. Although Riker does get the best line about Cochrane's attitude:
Riker: Someone once said, "Don't try to be a great man. Just be a man, and let history make its own judgements." Cochrane: That's rhetorical nonsense. Who said that? Riker:You did. Ten years from now.
Barclay and Geordi are obviously the most taken with him. Barclay has to drum up the courage to ask to shake Cochrane's hand and immediately dissolves in ecstatic babbling, while Geordi waxes so eloquent about how "Zefram Cochrane" is the first chapter in the introductory text for the required warp field course at Starfleet Academy, the grand 20-foot-statue of Cochrane that was built on the launch site, etc, that Cochrane freaks out and tries to escape from the launch party because it's too much pressure.
While not the best movie, there's something heartwarming about the awed reaction of Captain Picard upon meeting Captain James T. Kirk in the Nexus in Star Trek: Generations.
And touchingly, Kirk, initially dismissive of Picard, warms up to him almost immediately upon learning what ship he commands.
Lars von Trier gets to work with and even impersonate his lifetime mentor and role model Jørgen Leth in a documentary film called The Five Obstructions.
Several Avengers admire each other. Notably Tony Stark is a huge fan of both Dr. Bruce Banner (it says something when Tony Freakin' Stark admires someone's else's genius) andThe Hulk, being one of the few who regards Banner alter-ego as a superpower, not some condition to be cured.
Stark: Your work on anti-electron collisions is unparalleled. And I'm a huge fan of the way you lose control and turn into a giant green rage monster.
In Pulp Fiction, Jules and Vincent turn into giggling schoolgirls when they realize the "cleaner" being sent out to deal with the body they created is none other than Winston Wolf.
Many, many characters behave this way toward Gilderoy Lockhart in Harry Potter and the Chamber of Secrets, to the point where Harry — the actual hero of the series — gets forced to spend a detention helping the man answer his fan mail. Lockhart's general incompetence, though, implies that he doesn't deserve his fame; he eventually reveals that he made a career out of finding people who did impressive things, wiping their memories, and claiming he did those things himself. Right afterward, in a fit of irony, Lockhart blanks his own memory while trying to blank Ron and Harry's memories. Ron and Harry never seem to mention his secret to anyone, so Lockhart's fame is mostly intact.
In one Batman short story, "Fat Tuesday", a man wears a Batman costume to Mardi Gras, because Batman is his hero. He is kidnapped by a local gangster, but the real Batman saves him. The real Batman was dressed up as his hero, Zorro. Which a bit of Lampshading as Zorro is basically what Batman was based off of.
At the end of The Last Hero, Cohen and the Silver Horde meet Fingers Mazda, the Discworld version of Prometheus in this manner. All Mazda understands is that some old guys just freed him from the chains that kept him bound to a rock where vultures could come eat his liver and handed him a sword.
The Dresden Files: Harry Dresden, meet Kris Kringle a.k.a. Santa Claus a.k.a. Donnar Vadderung a.k.a. Odin
In Pretty Guardian Sailor Moon, Usagi is a big fan of Minako Aino, who also happens to be Sailor V's real identity, though Usagi doesn't find this out until very late on in this version.
"The Waters of Mars" does an interesting one when the Doctor meets Adelaide Brooke, captain of the first human base on Mars, in 2059. To him, she's another historical figure he particularly admires, and he hates that her death is a Foregone Conclusion he can't prevent without breaking the laws of time. The audience, not being Time Lords, can't really appreciate this in the same way, whereas it's very obvious how much the Doctor wants to save her, so it's easy to be tempted along with him — which is of course the point.
Vincent van Gogh can be added to the tally as of the fifth series. Eleven and Amy are no more subtle than Ten and Rose in their squeeing, much to Vincent's confusion.
Amy and one-shot companion Riddell are both quite excited about meeting Queen Nefertiti.
In Kaizoku Sentai Gokaiger,Sixth Ranger Gai is a complete and total Super Sentai fanboy, and will flip out whenever he meets one of the older team members (and then ask for an autograph). On a couple of occasions they have fun with this; when he meets Abaranger's Yukito he fanboys, but then he sees Emiri and says "...And somebody I don't know!", and when the team meets Ohranger's Momo Maruo, she herself fangirls a little.
Of course, everyone was doing some sort of squeeing over the TOS crew (or at least the big three). O'Brien was pretty proud that he lied to Captain Kirk, and even Worf said "It would be an honor to meet him" in a tone that can only be described as the Klingon equivalent to squeeing.
Worf has met 3 of his personal heroes; Kahless, Kor, and Martok (the real one), and while Klingons don't exactly squee per se, his reaction on meeting all of them has been more of the aforementioned Klingon equivalent.
Worf gets major respect from even the highest ranked Klingons.
In the TNG episode "Relics", the crew is amazed to meet the original Miracle Worker himself, Montgomery Scott. La Forge, being the chief engineer of this ship, is especially taken with him. It sours a bit, that the crew regards him as a relic.
But then Scotty does what he did 80 years ago all the time and help save the Enterprise, and he's promptly regarded as the Miracle Worker again, and Picard even gifts him a shuttle.
Star Trek: Kirk himself is no stranger to this trope. In "The Savage Curtain", e pretty much acted the same way when he got to meet Abraham Lincoln. In the same episode, Spock briefly showed emotion when he meets Surak, the "the father of Vulcan civilization" as Spock describes him. (But he quickly deduces that Surak, like Lincoln, is not truly real.)
Star Trek: Voyager: Janeway's interaction with the Leonardo da Vinci hologram also had this vibe. Likely due to the fact that Janeway is a scientist, while Leonardo literally is the scientist.
The crew come to view Lt. Reginald Barclay, himself a bit character on TNG this way after he managed to get a Starfleet message to them for the first time in four years.
Buffy the Vampire Slayer: In probably the only case when it happened between a hero and a villain, Buffy squeed pretty hard when she met Dracula.
On his first appearance on Ghost Hunters, Meat Loaf is squeeing over getting to investigate with TAPS while they are squeeing over getting to meet him.
He's less obvious than most examples, but Cam Mitchell is definitely one of these at the beginning of season 9 of Stargate SG-1. So much so, in fact, that he spends all of his time Putting the Band Back Together rather than enjoying his newfound command.
In "The Examination for Lieutenant" from Horatio Hornblower miniseries, Horatio is if not a complete hero yet, then surely an up-and-coming rising star of an officer in the Royal Navy. He squees — well, he almost squees, because he's a shy and solitary boy — when he meets Captain "Dreadnought" Foster who is a Living Legend. Foster enjoys his admiration and is taken with the young acting lieutenant. Horatio ends up disillusioned when he finds out that Foster breaks rules and concludes that he doesn't care much for lives of his crew.
On Murdoch Mysteries, Detective Murdoch, our hero who loves science and uses various applications and gadgets during his investigations, is always delighted or thrilled to meet famous inventors and scientists, but he absolutely fan-boys over some of them, like when he meets Nicola Tesla, Alexander Graham Bell, Thomas Alva Edison or especially Guglielmo Marconi whom Murdoch met when he was setting up wireless telegraph in Nova Scotia.
In Persona 4, despite regularly diving through television screens and battling the physical embodiment of people's suppressed selves, Yosuke can't help being completely starstruck when teen idol, "Risette" comes to town.
Also, in the game's sequel, Persona 4 Arena, Chie comes to admire Akihiko so much that she starts to call him her master.
The Ouendan of the Japanese game Osu! Tatakae! Ouendan appear wherever they are needed, sometimes for a reason. In Ouendan 2, a pop star is kidnapped, and the Ouendan are there to support fans in reclaiming him because they clearly are fans themselves.
Ratchet of Ratchet & Clank is like this a few times. He treats Captain Qwark as one (until he realises he's not so great, reacts with awe towards a hoverboard champion and is rather excited that the spaceship he is stationed on has a gamestation in the third game.
Mass Effect: Commander Shepard gets this from time to time, since Shepard's already a badass with a rep in the first game. In the second, Shepard's only the savior of the entire galaxy. One could almost argue that there's less squeeing over Shepard than there should be. Especially since Shepard's back from the dead. Though given the memorials to the Commander on a half dozen planets, Shepard's home colony adopting Shepard's face as their official logo, and (according to one news report) raging extranet arguments about what Shepard's return means, you can say things are pretty Squee-ish. If you chose the Paragon ending in the first game the turian weapons dealer on the Citadel positively gushes over Shepard. Even before completing his loyalty mission, it's clear that the tankborn mega-krogan Grunt has nothing but total respect for Shepard and is infuriated whenever anyone insults Shepard in anyway or spits on Shepard's name.
In Mass Effect 3, it's clear that Shepard is quietly awed by the fact they've discovered a Prothean who's been in stasis for 50,000 years. This is however, quickly overshadowed by the sheer amount of squee emanating from Liara, leading Shepard to suggest she handles asking their questions, since she looks like she's about to explode.
Altaïr, protagonist of the first Assassin's Creed, has a mild fanboy in Ezio, protagonist of the nextthreegames. They never actually meet, because they were born three centuries apart, but Ezio adopts Altaïr as his mentor and tries to follow in his footsteps and learn from his mistakes.
The Player Character from Saints Row The Third reacts in this way when meeting the current mayor of Steelport: Burt-FUCKING-Reynolds.
In the Dragon Age: Origins expansions Awakening and Witch Hunt, companions Sigrun and Ariane have this reaction to the Warden if he/she is a casteless Dwarf or a Dalish Elf, respectively. The Warden is a Folk Hero to all of Ferelden, but a Warden from those backgrounds obviously has a special appeal to individuals from those two (historically much-persecuted) groups.
In Dragon Age II, Charade Amell has this reaction to Hawke, after discovering that her long-lost cousin is the Champion of Kirkwall she had grown up hearing tales about. Hawke later receives a very squee-filled letter full of questions, making it clear she's something of a fangirl.
Hawke also receives this from Tallis in Mark of the Assassin, especially if begun after Act 2 and if Hawke earned the respect of the Arishok. This is because Tallis is actually a Qunari agent and explains that rather than revile Hawke for defeating their leader, all Qunari now know and respect Hawke as a honourable Worthy Opponent.
If importing a save with the Human Mage Warden from Origins, several conversations make it clear that Hawke's family are very proud and huge fans of their second cousin. As an Apostate who often finds her magic a curse, Bethany especially is amazed that a Mage became the saviour of Ferelden.
In Psychonauts, Raz is a big psychonauts fanboy and really looks up to them; Agent Cruller in particular. Lili is also shown to be a bit of a fangirl herself.
Trucy Wright in Apollo Justice: Ace Attorney over the Gavinners, despite the fact that Gavin is actually their opponent in court. Apollo himself has some fanboyish tendencies concerning Phoenix Wright.
The Order of the Stick: Roy meeting his grand-father in the afterlife. Roy is also quite fanboyish when meeting with Gary Gygax earlier — probably channeling the author there. Given that Gygax was one of the people primarily responsible for the setting that Roy exists in, this reaction is entirely justified - he could only get closer to meeting his maker if Rich Burlew drew himself in. Later, Laurin subverts it: she remembers how much of a fan of Julio she had been, but that had been when she was younger.
Villainous example from Homestuck: despite being an omniscient, nearly omnipotent "first guardian" of Alternia, Doc Scratch is apparently a big fan of Sweet Bro and Hella Jeff, bringing up many of the same Memes that the rest of the cast does. There is actually a very good reason for this: He was made in part from a magic cue ball and one of Bro's puppets, and Dave (who wrote SBaHJ in-universe) has a similar sense of humor to Bro.
Also, the post-scratch Trolls are all huge fans of their respective ancestors, and when they finally meet them, squeeing ensues.
Alloy from The Descendants to the point where he has to be told to control himself when meeting other heroes by his teammates.
Aquerna and some of the other Underdogs of Whateley Academy in the Whateley Universe have a fan club for Fey. This is really embarrassing for Fey, since she's their age and still in high school.
After Doug Walker did a Nostalgia Critic tribute to Siskel and Ebert, Roger Ebert tweeted about how much he liked it; Doug had that tweet printed out and framed for his wall. He was also very enthused to have the creative team of Animaniacs on for a tribute to their show.
Eric Rodriguez did a countdown of the the Top 10 Voice Over Actors. Not only did two of the actors mentioned in the list watch the video and tweet about it to their followers (Rob Paulsen and Tara Strong), but Rob actually emailed Erod to tell him how much he loved the video.
The Knights Of Fandom are an online group of fangirls and fanboys who unite for the dual purposes of being huge fans of whatever they enjoy and fighting cyber-bullying. Their Tumblr account invokes this trope by name ("We are the Knights who say 'Squee'!"), and they certainly lived up to the trope when Grey DeLisle joined their ranks.
Ruby Rose from RWBY has dreams of becoming a Huntress. When she meets Glynda Goodwitch, an active Huntress, she Squees and asks for an autograph.
Penny did this in an episode where everyone's favorite detective family has to protect a rock and roll star.
Plus there is one where a MAD agent also happens to be Gadget's favorite actress.
Katara of Avatar: The Last Airbender is a total Jet Fangirl for one episode. Hey, All Girls Want Bad Boys. She loses her capacity to squee harder than most examples here when she learns that he's not just bad, he's a narrow-minded jingoist who considers killing a town full of innocent Earth Kingdom civilians a ringing success for the rebellion, just because there happens to be a Fire Nation camp nearby.
And Bats himself to Sherlock Holmes, in the episode where he went back in time. At the end of that episode, Holmes asks how he knew who he was. "Everyone knows who you are. You're the world's greatest detective." (World's Greatest Detective is usually a title given to Batman.)
In Justice League, Captain Marvel finally meets his idol Superman, only to discover that he's nothing like he thought he would be. After Supes beats the tar out of him, destroying the "reformed" Lex Luthor's new city in the process, he resigns from the now understandably repentant JL with the words, "You just don't act like heroes." Contextually, the Big Blue's attitude had a lot to do with recent events. It didn't help that Lex Luthor had gone out of his way to make things look suspicious to Supes so he'd go off half-cocked, thus soiling the League's reputation. The same happens with the Ulti-Men later on.
Green Lantern John Stewart was a big Justice Guild fan when he was a kid.
The members of the Sushi Pack fall into this occasionally. In "The World's Tastiest Heroes", Ikura fanboys over all the superheroes on "The World's Biggest Heroes" and even gets backstage passes to the show. The superheroes all turn out to be horrible braggers and just laugh at the Pack when Ikura introduces them as heroes, too.
In "Yam Yakkers," Ikura and Wasabi are looking forward to getting the autograph of the actor playing Aquabot-boy, and while Tako claims to be a fan of Aquabot-boy, not the actor, he still does a happy dance when he gets an autograph, too.
Raven and Starfire basically dissolve into a puddle of gently Squeeing goo when they first meet Aqualad.
The whole team drools over Val-Yor to a scary degree, trusting the stranger to the point of joining a mission of his far from Earth way too quickly. Then it turns out he's speciesist and hates Tamaraneans.
Also, in the flashback episode showing how the team first met, Beast Boy was very excited to meet Robin, who was, of course, already famous.
The whole team save Beast Boy squeed hard when BB received a letter from the Doom Patrol, a famous (in-series) and established team of superheroes. They stop squeeing and start asking themselves questions when BB reveals he had been in the team before getting fired.
Ben squeals like a fangirl when he sees a commercial for a new live-action "Sumo Slammers" movie.
Also in a more recent episode, Ben's girlfriend said the reason she didn't get jealous when a movie star kissed Ben was because "he's gotta bigger crush on Captain Nemesis than he does on Jennifer Nocturne".
In Danny Phantom, a villainous example is given with the Green Bay Packers fanatic Vlad Masters.
In The Penguins of Madagascar episode "The Red Squirrel" Skipper, Kowalski, and Rico all squee over meeting and working with the legendary Special Agent Buck Rockgut. Skipper even claims to have "patterned his whole life" after Rockgut. Their enthusiasm fades when he accuses first Private then Kowalski of being the villainous Red Squirrel.
A bizarre example happened in the Codename: Kids Next Door episode "Operation: T.R.A.I.N.I.N.G." After Tommy bluffed Father (the Big Bad of the show) into thinking his autograph book was the Code Module, Father seemed pretty excited to see that it had Numbuh 362's autograph in it, despite the fact that she's his Arch-Enemy.
In Teenage Mutant Ninja Turtles (2003), Mikey often feels this way regarding established super-heroes, such as Silver Sentry and the Justice Force.
Donatello gets a moment like this every now and then. Most notable is in the third episode, when April mentions that she used to be employed by Stocktronics and— by extension— Baxter Stockman. This pedestal breaks within five minutes, with little fanfare. There's also an episode that sets up to this, with Don telling Mikey about how a monster hunter is an accomplished biologist and psychologist... but also a "Certifiable nut-case!"
There was a definite Broken Pedestal moment when he met Green Lantern John Stewart. However that was quickly resolved upon learning the Lantern Static thought he'd met was Sinestro impersonating him.
Same with Superman in another episode, not to mention both he and Gear getting their minds blown when the Justice League itself asks for their help in their crossover episode (well, Static's help, anyway.)
In My Little Pony: Friendship Is Magic, Rainbow Dash is a very skilled flier, winner of many awards, implied to be the fastest living being on the planetnote excluding Pinkie Pie, who has access to Offscreen Teleportation, and bearer of the Element of Loyalty, but she's still a total fangirl of the Wonderbolts and hopes to join them someday.
She has a similar reaction when meeting Daring Do.
Twilight Sparkle, The Hero of the series and one of the most powerful magical practitioners in all of Equestria, is this to its Big Good, PrincessCelestia. In fact, it was a display of Celestia magically raising the sun that first inspired Twilight to take up the study of magic as a filly.
Sadlygrove Percedal greatly idolizes his mentor Goultard. Though ironically back when the two met, Sadlygrove was the only person not to know Goultard in a town populated by fanatic fans of the legendary warrior.
Amalia Sheran Sharm, despite being herself an heroine and a princess, can easily turn into a complete fangirl around renowned people, like the Justice Knight or the Masked Gobbowler.
The Adventure Time episode "His Hero" featured Finn and Jake idolizing a great hero called Billy (Jake: "I wanna be the dog you, Billy!"). At the end of the episode, after they restore his faith in heroism, he declares them his heroes and they squee out so hard he gets really uncomfortable and has to ask them to leave.
In Kim Possible, Frugal Lucre is a villainous version, driving Dr. Drakken to distraction with his hero-worship when they're stuck in prison together. After they get out, Lucre makes a pest of himself again by seeking out Drakken as a mentor.
In the 1993 NHL playoffs, the Los Angeles Kings eliminated the Vancouver Canucks in the second round. During the team handshake, up-and-coming young Canuck star Petr Nedved asked his idol, the Kings' Wayne Gretzky, for his stick as a souvenir. Needless to say, Vancouver fans were not amused at the antics. For completelydifferentreasons, this actually turned out to be his final act as a Canuck.
Reportedly, one of the New York firefighters doing rescue work in the wake of the 9/11 attacks had a complete fanboy moment upon discovering that one of the volunteers serving them food and water was none other than Kevin Conroy of Batman: The Animated Series fame.
Even cooler, the firefighter then asked Conroy to say something in his Batman voice. And then it gets even better than that: the entire room heard the famous Batman voice and then EVERYBODY Squeed!
Similarly, more than one volunteer helping out after the Touhoku Earthquake/Tsunami of 2011 apparently had had similar reactions when they found out that the famous seiyuu Norio Wakamoto (who actually was a policeman before becoming a voice actor) was among them.
Tim Allen and Buzz Aldrin mutually fanboyed each other when they had an opportunity to meet.
Movie stars and astronauts always make for good mutual squee-bait. During the filming of Apollo 13, Jim Lovell and Fred Haise visited the commissary and were awe-struck by all the big-named stars walking around. The stars, meanwhile, were used to seeing each other every day, but reacted with "ZOMG, Apollo astronauts!" at Lovell & company.
French comedian Jamel Debbouze and French soccer star Zinedine Zidane are complete fans of each other. It shows whenever they're invited together on television.

An excerpt from Growing Up Brady: I Was a Teenage Greg by Barry Williams, about his time on The Brady Bunch:
[Following a story about a time when Henry Kissinger visited the set.] By now you must have asked yourself, "Why on earth would Henry Kissinger go out of his way to visit "The Brady Bunch?" The answer, quite simply, is that he was trying to impress his daughter. She was a big "Brady" fan, and when she asked her father if he might arrange for her to meet us, he simply made a phone call, blew off an afternoon full of globally significant meetings, and arranged for the visit. I still find it nothing short of amazing that a man who was arguably the single most powerful politician in the world needed The Brady Bunch to impress his kid - sort of an eerie commentary on the power of the tube and its significance on the lives of American children.
An even more blatant example of the egregiously potent power of "The Bunch" came when astronaut James McDivitt appeared on the show in a cameo role. McDivitt had piloted both NASA's Gemini 4 and Apollo 9 missions, and he had been to the moon, for chrissake; but when he got to our set, the first words out of his mouth were "Boy, being on The Brady Bunch is gonna make me a hero at my house."
Monkey Punch (creator of Lupin III) upon finally meeting Mort Drucker of MAD, who was one of his major artistic influences and basically his hero. Though there was a Language Barrier, Omniglot Jan Scott Frazier was able to help them communicate.
David Tennant, world-famous actor and easily in the running for "most beloved Doctor of all time", found himself incapable of doing anything other than squeeing like mad upon meeting his childhood idol Elisabeth Sladen, aka Sarah Jane Smith. He openly admitted that "it was always the Doctor and Sarah" and that working with her was a lifelong dream come true, and called her "the one true assistant". The fanboying is easily visible in every scene they share.
Tennant and Peter Davison too, who he got to work with in "Time Crash". Davison is the Doctor that Tennant watched while growing up. The dialogue sounds less like the Tenth Doctor fanboying over the Fifth Doctor and more like Tennant fanboying over Davison. He even points out several aspects of his performance that were inspired by Davison.
Senator Elizabeth Warren, formerly an outspoken but otherwise unassuming consumer advocate, has become a hero of the liberal left in American politics and a rallying point for anti-corporate-welfare activists all around the nation. But when she joined forces with Hillary Clinton to introduce Senator John Kerry at his confirmation hearing for Secretary of State, she spent most of the time she wasn't talking gazing at Clinton like she couldn't believe she was sharing a table with the most famous woman in the history of American politics. Even before then, during her Democratic Convention speech, Warren called Clinton "one of the coolest women on this planet."
Beloved fantasy author Tamora Pierce, on giving up writing comics only to be asked to help write a miniseries for Red Sonja by the legendary Gail Simone: "I know, I know, I swore off comics, but when the splendid Gail Simone asks, what's a girl to say but ::wagging tail thump thump thump:: 'Sure, Gail, sure! Which way should I go? Which way should I go?' ::tongue hanging out, tail bumping furniture::"
Noah Antwiller of The Spoony Experiment has expressed great fondness and admiration for Richard Garriot, creator of the Ultima series, calling him a "god of geeks" in his review of the original Ultima. Then when he got a sit-down interview, Garriot admitted to being a fan of Noah's.
Tyrese Gibson, during a convention appearance shortly before the release of the Film/Transformers live-action movie, admitted to Peter Cullen that he'd never had a dad growing up, but he did have Optimus Prime.
