Professional Butt-Kisser

"Chief Hearst: Mauser, you are the the most incredible ass-kisser I have ever seen.

Sgt. Mauser: (smiling) Thank you very much, sir. I do my best."

- Police Academy 2: Their First Assignment

Like the name says, the Professional Butt-Kisser is a career sycophant and Yes-Man. They don't care who is in charge so long as they're the right hand man. If their current boss were to meet an untimely end (or just get fired/demoted) they will happily offer their services to their replacement, even if they just saw how the new boss killed the old one! Despite their desire to be close the reins of power, they never harbor any ambitions of their own boss-hood, much less betraying their current boss (weeell... until the new one pushes them out of the job, anyway).

Just like they lack ambition, they are also devoid of all malice; both because they usually qualify as a Minion with an F In Evil if their master is a villain, and are in no way sad or angry their last boss is gone. Kind of like a True Neutral bureacrat. Interestingly, they are usually at least competent at their job as personal assistant (they are never The Dragon), though rarely to Hypercompetent Sidekick levels. Where they do excel is at shmoozing their new boss into accepting them, even to the point of getting an Ax Crazy villain to not just let them live, but convincing them they're more useful alive and working for them. Despite their (evil and crazy) boss' strange, abusive or incompetent behavior, they never feel put out and seem to derive some strange satisfaction from serving someone so powerful.

It's worth mentioning that despite the utterly slimy nature of the character, they tend to get off fairly lightly in terms of divine retribution. It may be because of the Stepford Smiler-like lack of malice, or the lack of concrete evil deeds.

Often doubles as an Obstructive Bureaucrat and/or Smug Snake. See also Punch Clock Villain and Battle Butler. Contrast Chronic Backstabbing Disorder; both have little loyalty to their allies, but the Professional Butt-Kisser never rebels. See Teacher's Pet for the Professional Butt-Kisser in training.

Anime & Manga

 * Diethard from Code Geass is one of these, a Britannian newshound who joins the Black Knights largely because he sees them as the winning party.
 * Demagawa in Death Note.
 * Takayama's secretary in Witchblade is a cross between this and Battle Butler. When he has no problems with shifting his loyalty to the new boss. He is, however, willing to stay and  to defend Tokyo from an onslaught of berserk robots. Also, he had guts to stand and face an insane murder-cyborg with a weapon that didn't even significantly slow her down.
 * Thunderblast in Transformers Cybertron is this meets My Girl Is a Slut. She doesn't want to be the most powerful, unlike most of the serious villains - she wants to have the ear (and maybe more) of the most powerful. YMMV on whether she is also a parody of Ms. Fanservice.

Films -- Animation

 * Wiggins is this to Radcliffe in Pocahontas, which is why he may come off as gay.

Films -- Live-Action

 * In Coneheads, INS Agent Seedling's assistant Turnbull (David Spade) manages to become a confidant to the leader of the Coneheads' people after he and his boss are captured and enslaved.
 * In Demolition Man, associate Bob manages to survive Doctor Cocteau's death by working with Phoenix to defrost other convicts, and after Phoenix bites it he manages to get employed by the rebel leader Edgar Friendly (who tells him to stop wearing the kimono because he thinks he looks like a couch with it, and pick a hair color).
 * Gretchen Weiner, Regina's second-in-command in Mean Girls. After Regina's downfall, Gretchen attaches herself to another Queen Bee. We last see her brown-nosing in Vietnamese!
 * Chad in In the Loop takes this trope and tries to turn it into an artform. Unfortunately, he combines it with being a Smug Snake with the result that the people he tries to suck up to barely pay him any attention and everyone else just thinks he's a creep.
 * The B-movie Circuitry Man (or possibly it was some other equally-forgettable flick) features a female Mook who is loyal to her "Boss", but cheerfully switches allegiance the instant her current employer gets killed; this happens two or three times in the course of the movie, and at the end, she survives to drive off into the sunset with Boss #4 or #5...
 * Comedian Larry Miller is to Professional Butt Kissers what William Atherton and Christopher McDonald are to Smug Snakes; nobody does 'em better.

Literature
"Tobias: How exactly do you program a computer to kiss butt like that?"
 * Casper in The Story of Henri Tod (one of the Blackford Oakes series) gives the impression of this very much in the early part of the story.
 * There is a character exactly like this in the trope-filled novel Stolen from Gypsies.
 * The Igors in Discworld work like this -- perfectly loyal until the torch-and-pitchfork brigade come calling, then it's out the back door to find a new master. Genre-savvy characters have taken advantage of this to ask them how to get in and out unobtrusively.
 * In one of the Animorphs books, the gang encounters a computer with all the information they need. With every question they ask the computer, the computer responds with everything it knows, with an absolute bare minimum of four glorifications to Visser Three.


 * Mr. Collins of Pride and Prejudice is the Regency equivalent of this; while Lady Catherine de Bourgh is not exactly his boss, he does depend on her goodwill for future advancement, and ensures this goodwill (or, given Lady Catherine's overall disagreeable character, something close to it) through shameless grovelling to the point where he's sucking up to her when she's not even in the local vicinity.
 * Percy Weasley becomes this in the later Harry Potter books after he joins the Ministry of Magic, sucking up to anyone who is at all important. At one point he bows so low that his glasses fall off and shatter.

Live-Action TV

 * Dr. Jeffrey Steadman from Scrubs.
 * Dwight Schrute in The Office. Aside from the few episodes he's fired (and promptly rehired) or trying to usurp Michael's job.
 * Phil Smith on The Thick of It.
 * An offscreen example from 3rd Rock from the Sun: the family all know that their distant superior, The Big Giant Head, only got his position "by kissing The Big Giant Butt."
 * Played for Laughs and subverted with Evaristo Espina from the "La Oficina ("The Office") segment in the Chilean humor show Jappening con Ja, who had almost all the marking of the trope but is also fiercely loyal to his boss. He's so iconic that in Spanish Chilean slang, the word "espinita" is actually used to define the trope itself.
 * Weyoun on Star Trek: Deep Space Nine literally worships the Founders, the rulers of the Dominion. In fact, this trope is the hat of the entire Vorta race.
 * Hodges on CSI. He's always out to kiss up to the boss and doesn't really have any ambition, he wants to stay in the lab where he's happy. Grissom used to get terribly annoyed at him sometimes.

Pro-Wrestling

 * Michael Cole on Monday Night RAW and Friday Night Smackdown usually kisses the butts of just about every heel, except for Daniel Bryan.
 * Vince Mc Mahon's "Kiss My Ass" club is a literal version of this.

Sports

 * The University of Kansas is one of these to the Big 12 Conference, especially during the recent departures of four charter members (possibly due to the fact that they lose teams that they easily beat in basketball).

Theater

 * Cyrano De Bergerac: This is a more realistic, non villanous example: At Act II Scene VII, Cyrano discuss this trope with Le Bret, claiming that he will defy it. It should be said that in The Cavalier Years and now, this is Truth in Television: An artist is always dependent of patronage.

"Cyrano: What would you have me do?

Seek for the patronage of some great man,

And like a creeping vine on a tall tree

Crawl upward, where I cannot stand alone?

No thank you! Dedicate, as others do,

Poems to pawnbrokers? Be a buffoon

In the vile hope of teasing out a smile

On some cold face ? No thank you ! Eat a toad

For breakfast every morning? Make my knees

Callous, and cultivate a supple spine,

Wear out my belly grovelling In the dust?

No thank you ! Scratch the back of any swine

That roots up gold for me? Tickle the horns

Of Mammon with my left hand, while my right

Too proud to know his partner's business,

Takes in the fee? No thank you! Use the fire

God gave me to burn incense all day long

Under the nose of wood and stone? No thank you!

Shall I go leaping into ladies' laps

And licking fingers? or to change the form

Navigating with madrigals for oars,

My sails full of the sighs of dowagers?

No thank you !"

Video Games

 * In The World Ends With You, the third GM is one of these. Or Is She?
 * Pious Augustus in Eternal Darkness: Sanity's Requiem if he's working for Ulyaoth.

Web Animation
"Simmons: You're both an excellent leader and a handsome man, sir.
 * Simmons from Red vs. Blue, commonly referred to by Grif as a "kiss-ass". And not just Grif: pretty much anyone who's ever met Simmons is aware of his sycophancy. On one occasion, Sarge decided to forego commanding them to do something useful and just commanded them to do what they were going to do anyway (except for Grif, who made sarcastic remarks instead). Simmons' order was "kiss ass at will," which he did, with gusto.

Sarge: Excellent work, Simmons."

Web Comics
"Qarr: See, the first lesson of being 18-inches tall is: Find someone more powerful than you are, and glue your lips to their ass."
 * Qarr The Imp from Order of the Stick even have this as his personnal motto. At first working for Kubota by order of his higher-ups (well, lower-ups, since they're from the Lower Planes), he then tries to bind himself to Vaarsuvius (who killed Kubota) and ends up at the service of the IFCC.

Western Animation

 * Transformers Animated
 * Sunstorm (Sycophant Starscream) heaps praise and compliments on everyone. He especially praises the original and most brilliant Starscream, Of course, he's not nearly as awesome as you, wonderful article reader. You're so cool!
 * Lugnut too, though only for Megatron. He seems to not only worship Megatron in the most literal sense of the term, but he actually swears by him -- and he doesn't hesitate to remind Megatron of this fact in person. Even the megalomaniacal leader of the Decepticons sometimes gets tired of it, but keeps Lugnut around anyway because he's completely reliable.
 * The Simpsons
 * Averted by Waylon Smithers, whose devotion to Mr. Burns is genuine and absolute (and, well, more than just professional). It's also implied in one episode to be quite literal in Smithers' case, as he asks Mr. Burns, when the latter claims during a meltdown that he has nothing left but to kiss his sorry ass goodbye, if he could kiss Mr. Burns' ass.
 * Played straight with his lawyers though, who absolutely refused to inform him he was making bad decisions even when he was losing everything. Hell, when he did, they still said he made all the right moves and when he called them out, they agreed in the exact same way.
 * Wuya of Xiaolin Showdown happily offers to work for whatever villain happens to be the top villain, only to come crawling back to work for Jack Spicer when said villain gets defeated. As a matter of fact, Wuya is extremely competent herself, but when she's trapped in "spirit form" she has no choice but to enlist a partner in crime.
