Something's going on in the plot, and it's not good. Maybe there's a dramatic confrontation, maybe your best bud is losing a fight, but whatever the case, you need to get in there, fast, dramatically, and *THUMPCRASH!!*
All of you, listen up! For these cases, you need the Dynamic Entry!
The Dynamic Entry has three main elements: Speed — It has to be fast; Surprise — They can't see it coming until it's too late; and Violence — It's gotta hurt.
The most common form is a diving kick from off screen, usually directed mostly horizontally, hitting whoever happens to be on-screen at the time. Most of the time, it's not clear how exactly they launched themselves thusly. Often suggests a Large Ham or some-such (in which case the Dynamic Entry indicates an Incoming Ham as well). May overlap with Big Damn Heroes.
Contrast Diving Save. The "Hey, You!" Haymaker is a subtrope of this. See Your Door Was Open for the not-dynamic-but-just-as-sudden-or-unexplained entry. Sometimes combined with There Was a Door or Super Window Jump, for when the Dynamic Entry comes through a wall or window to increase the surprise factor. Can overlap with Attack Hello.
If the entry kills someone, it is probably a Surprisingly Sudden Death. If somebody else throws you, then it's a Fastball Special. If you need a rope, it's Fast Roping. It's almost always a key part of a Big Damn Heroes moment, and frequently a Big Entrance.
Compare Chandler's Law. See also Stealth Hi/Bye and Click Hello which are equally surprising but not immediately violent. In the Back can be used this way if the attacker isn't seen until he strikes.
This should not be confused with Feet-First Introduction.

Arguably, the Kool-Aid Man's preferred method of dispensing Kool-Aid to thirsty kids: Bursting through a brick wall and shouting ''OH YEAH!''
Several Stride commercials use this, with Stride executives or something else suddenly appearing and attacking people for not spitting out their gum, since it's "ridiculously long lasting."
One of the Old Spice commercials with Terry Crews involves him interrupting a Bounce commercial by smashing through the wall on a jet ski before shouting "OLD SPICE MAKES YOU SMELL LIKE POWEEEEEEEEER! It's so powerful it sells itself in other people's commercials!"
Some of the Ladbrokes commercials are disguised as commercials for items that don't exist, like energy drinks. However these get interrupted by an Italian commentator by him kicking a soccer ball into the actors face.
Anime and Manga
In Girls und Panzer, when Oarai's tankery instructor, Ami, turns up, she does so by having her Type-10 Main Battle Tank air-dropped by a huge transport plane, crushing the principal of Oarai Academy's new Ferrari. Why? Well why not?
Pictured above: This was Su's standard greeting to Keitaro in Love Hina. The page pic is particularly noteworthy because she runs across a rooftop to deliver one through an open window...and somehow lands with her legs wrapped around his head.
Come to think of it, the girls of 3-A will do this for just about any reason. Even to say "hello" in at least one case.
This happens a lot in Negima, whenever someone barges in a scene. It's sometime justified, such as when Asuna socks Eva to stop her from drinking Negi's blood, but it just gets bizarre when Little Miss Snarker Yue does it as she interjects in a perfectly mundane conversation between her classmates. Asuna is really fond of it. Recently, Chisame seems to be picking it up, too.
Done twice practically back-to-back in epic style in episodes 39/40 of GaoGaiGar. First, Soldato-J inadvertently saves Guy by riding a missile through a wall to fight the Arm and Eye Primevals. In the opening sequence of the very next episode, Mamoru bursts through the floor of the Main Order Room riding Galeon to rescue Mikoto and the GGG bridge crew from the Nail and Ear Primevals.
He gets a pretty good one in Movie Seven too, saving Goku from being throttled by Meta Cooler.
(Future) Gohan in the History of Trunks Movie. "That's ten points, now we're ti—"
Done spectacularly well at the end of volume 34 of Rave Master (Groove Adventure RAVE) when Haru comes crashing through a stone wall to kick Lucia in the face just before he can execute Elie. And then he screams "BRING IT!!!" in an extreme close-up. (The effect is slightly lessened if you realize Hiro Mashima copied the Dynamic Entry shot WHOLE from an early chapter of Tsubasa Reservoir Chronicle.)
It was so hard, in fact, that it broke the legs of the Gunmen he was riding in.
He also immediately chains it into the "HANDS-OFF-MY-BELOVED-LITTLE-BROTHER-PUNCH!!!", which breaks the arm of the Gunmen he was riding in. It's a two-parter!
More spectacularly, Gurren Lagann's first-ever hyperspace jump in episode 23. Simon uses the momentum to leap out of the robot, skid across a cavern and deliver a tooth-loosening "Let's see you GRIT THOSE TEETH!" punch to the suicidally remorsefulRossiu in the last second before the latter can shoot himself.
Also, Yoko's introduction in the first chapter. She crashes through the ceiling while firing her huge rifle. Along with a freakin' Ganmen.
Hiruma from Eyeshield 21 does this when he feels the Devil Bats aren't being awesome enough.
Kuchiha to Kon, on multiple occasions, in Amatsuki.
Futaba does this to Gargoyle with amazing frequency in Gargoyle of the Yoshinagas. Probably one of the younger dynamic kickers on this page.
In one episode of Ghost in the Shell: Stand Alone Complex, Batou is under fire by invisible assassins while trying to protect a witness. When the Major comes to the rescue, she drives her fancy sports car right into the lobby and up a short flight of stairs, only to jump out and shoot the attackers. Which in fact is just the buildup for the true Crowning Moment Of Awesome that follows immediately.
Neon Genesis Evangelion. Episode 19. Misato and co. are about to be vaporized by an Angel, when Unit 01 bursts through a wall and punches it in the face. You read that right. Dynamic Entry, as performed by a Humongous Mecha. That's what happens when you make Shinji mad.
End of Evangelion. Twice: Misato headshots a soldier from off-screen, guns down another while running and pins the last one to the nearest wall when she stops, dropping a Pre-Mortem One-Liner before she shoots him in the head at point-blank range. A while later, Asuka opens her Last Dance against the MP Evas with a flying kick to her first target's skull, turning it into a massive blood splatter on impact.
Rebuild of Evangelion 2.0. An Angel appears and blows a fleet of battleships to hell. Misato's car is under fire... then Unit 02 is paradropped from the air, avoids the Angel's attacks and opens fire with a crossbow-like weapon while falling; finishes the job by landing on the core so hard it shatters. You heard that right, by the time Unit 02 lands the Angel is already dead.
Mari pulls one off right at the beginning of the film. The Angel is about to escape, the base commander asks "what in the hell is Unit 05 doing?!"... cue said Eva firing it's thrusters underneath the hole the Angel just exited, flying after it and impaling it onto a pillar while the pilot screams "No, you DON'T!!! GET BACK HERE!!!".
Also at the end of the film when Kaworu pulls one of these all the way from the moon, impaling Unit 01 with a Longinus Lance thrown from orbit in the process.
Baccano!'s Rachel features this method of entry during her Big Damn Heroes moment when she saves the Senator's wife and daughter.
Ryoma's Dynamic Entry in the Shin Getter Robo vs. Neo Getter Robo OVA, which involved jumping from the head of a 200 feet tall robot to dropkick a dinosaur in the face.
In Hayate the Combat Butler, Yukiji does this in Chapter 151 by kicking a bear in the face. Hayate also pulls this routinely.
In the Manga though, it is Honey who pulls this off.
CLANNAD: Done by Kyou to Sunohara when the latter was messing with her pet boar - immediately preceded by a well-aimed textbook to the face.
Arihiko of Tsukihime manages to compress the statement "Good morning, Shiki. I'm disappointed that you never told me you had a sister" into a running dropkick (and dismisses Shiki's insistence that this might have been a bit excessive).
In Manabi Straight, Manabi makes this her greeting to her homeroom-teacher-ally upon learning that her much-awaited, blood-and-sweat-planned School Festival was to be canceled out of nowhere.
Gundam 00's Graham Aker seems to love this, most notable being during ep4 of S2 where he intercepts the 00 Gundam with an aerial tackle just as it's about to destroy the A-Laws carrier.
No one could forget the absolutely epic moment in episode 35 of Gundam SEED: a ZAFT mobile suit is about to blow away most of the good guys then BAM! Enter Not Quite Dead Kira Yamato and his shiny new Freedom Gundam, blowing away the offender's weapon before decapitating it with a combination of a high-speed flyby and a beam saber. Absolutely no one saw that one coming.
Kira and the Freedom have a knack for this kind of thing, as it happens multiple times in the sequel. He even saves the Minerva's bridge crew in the exact same way he saved the Archangel's back in the original series! The guy certainly knows how to make an entrance.
Isshin Kurosaki from Bleach does this to his son Ichigo every morning. It was even featured in one of the openings for the series. Hell, it happened in the very first episode ever when the poor boy walks into his house! (Although My Way Entertainment managed to make it even awesomer in one of their parodies...)
Komamura pulls one on Poww, who has Ikkaku down for the count. How? He punches him in the face. Which sends Poww flying into a house.
In the manga, Nel and Pesche return to the story via pulling these on Ichigo after his meeting and brief fight with Ivan Azgiaro.
Saito from Zero no Tsukaima crashes through an expensive-looking glass window and slashes downward at Viscount Wardes just in time to interrupt a wedding. Although most dynamic entries seem random and deus-ex-machina-ish, this one was justified because of Saito's variant of the Magical Eye allowing him to hear and see through his master's senses.
Suzaku from Code Geass has a couple of these. Once in the first season, when he smashes through a window to attack Mao and a really epic one in R2 episode 21, when he drops from the ceiling to knock out all the guards after Lelouch declares himself Emperor, a move which earned him one of the most amusing of his many nicknames, Roofzaku.
Episode 23 of Fullmetal Alchemist: Brotherhood is basically Dynamic Entry: The Episode. Pretty much everyone gets one, though it's hard to beat Ling bursting up from the sewers to shove a grenade down Gluttony's throat as the best.
Fullmetal Alchemist: Brotherhood in general is full of these. Note The return of Lanfan in episode 47.
And, in the manga, Izumi is the master of these. Her very first introduction was a freakin' flying kick that took 2 sheets of awesome!... into Edward's face. But still awesome!
D.Gray-Man featured a truly epic scene in chapter 139 when, during Lulu Bell's assault on the Black Order HQ, Allen dropped down from overhead and sliced a Skull in half lengthwise, then announced that This Is Unforgivable while still standing on top of his BFS.
Full Metal Panic!: Kaname does this multiple times. In a broader definition, Sousuke also pulls one off with the Arbalest in Khanka: he leaps over a Savage, stabbing it's neck in the process then runs off without stopping for a moment.
And in the Hetalia 2010 Bloodbath we have Iceland arriving at Germany's house in a Santa sleigh.
Although The Big O is probably one of the slowest moving robots in anime, it manages to score several throughout the series. In episode 13, Big O rises from beneath the ground to save Roger from psychopath android Red Destiny. Big O does this by smashing said android into the ceiling of the subway tunnel both Roger and Red Destiny were standing in.
Additionally, Big O punches through a wall to save Dorothy from a spider-mech in season 2.
Not to mention how it's usually summoned. It usually shows up coming out of the ground and sometimes collapsing a building for good measure.
For Durarara!!'s Shizuo, jump-kicking people is simply too ordinary an introduction. Instead, he throws vending machines at their heads.
Dynamic Entry is taken to its logical conclusion in Vol. 9: there's a part where all but one character enters the scene by jump-kicking or trying to jumpkick someone (mostly Izaya) in the face.
Ayu from Kanon has many dynamic entries upon an unsuspecting Yuichi, especially early in the series.
Earlier on in Sayonara, Zetsubou-Sensei, Maria had a habit of delivering flying kicks, generally to Nozomu, because she couldn't distinguish things she saw on television from reality. In one instance, Harumi attacks Chiri with a dynamic entry kick after Chiri insults her manga.
In the one of the last Hoenn episodes of Pokémon: Advanced Battle, At the End of the Fray (AG131), Team Rocket was working for a guy who was able to do this...by PUNCHING THROUGH THE WALL.
Brock first appears in Advance Generation by throwing Forretress (using Explosion as soon as he was released) at a flock of Taillow that was menacing Ash, May and Max.
Once Ash and the gang enter Pinwheel Forest, a Sewaddle appears out of nowhere, kicks Pikachu to the ground, bites it, and uses String Shot on Ash. Ash, of course, thinks that Sewaddle is cool, and ends up catching it.
In the opening of the Koihime†Musou OVA, Rinrin tried to do this. Didn't work, and was more for laughs than anything else, but it was close enough.
To Aru Majutsu no Index has several of these, including many from Kuroko to get close to Mikoto or to keep someone else from getting close to her.
Also Touma pulls several of these for a last-second spell cancel or fist to the face
One of the most epic examples was Touma blowing open the doors to a church to save Orsola from Agnese and her nuns, backed by a blazing wall of fire created by Stiyl's fire demon Innocentius.
Suite Pretty Cure ♪: Hummy has a tendency to fall from the sky, all four legs spread out wide. she has shown the ability to do this even indoors in areas where there is no logical way for her to have gotten where she's falling from.
A minor subversion in One Piece on Fishman Island. Luffy bumbles out of a shark's mouth he was hiding in at the time before performing a soru and kicking the current Big Bad right in the chest. It's less bumbling in the manga.
In the Sabaody Arc XDrake saves Urouge's butt by Dynamic Entrying (albeit using a slight variation) a Pacifista.
Near the end of the CP9 saga, Vice-Admiral Garp, Luffy's grandfather, enters into the room where the Straw Hats are staying by punching through the wall. When he later orders his subordinates to fix it, he states that he entered that way because it's cooler. His subordinates counter by making him help with the repairs.
In the Excel♥Saga manga, Excel greets Elgala's face feet first, screaming at her for not being around to help with Hyatt's latest, and possibly actual, death.
Right when Nao was losing hope in the first Revival round of the Liar Game, Akiyama appears from the window which was definitely not on the first floor.
Variation in Ai Yori Aoshi: Chika pulls a flying tackle on Kaoru that ends with her crotch right in his face. And holds on for far longer than poor Kaoru is comfortable with.
InuYasha: Sesshoumaru's a big fan of both the Big Entrance and the Dynamic Entry. One of his most notable examples is when Kagome, Sango and Miroku were dying from Mukotsu's poison and Mukotsu tries to rape Kagome for good measure. Claws rip through the side of Mukotsu's body, saving everyone just in time... and the reveal is that it's Sesshoumaru who made the grand entrance, not Inuyasha. The sole reason this isn't an example of Surprisingly Sudden Death is because Mukotsu is one of the walking dead, resurrected by a shikon shard, so only the removal of the shard from his body will actually kill him. Sesshoumaru achieves that on his second attack.
Mii enters episode 3 of Popotan this way. Mai is not amused.
In Death Note episode 14 (Friend), Misa jumps onto Light, pushing him to the ground. Needless to say, Light is not amused.
Light: (thinking) This is the first time in my life that I've been provoked to hit a woman.
In Detective Conan chapter 830, Sera Masumi pulls this on none other than Kaitou Kid who is disguised as her, thinking she was a boy and even going as far as stripping her outta her clothes (save her underwear and shirt). The real reason is that... the girls' toilet was full, so Sera had to use the boy's one.
While Black Lagoon features no shortage of the guns-blazing variant, there's a notable subversion in the 'Roberta's Blood Trail' OVA: a bunch of hapless Colombian Cartel mooks attempt a door breach on a room full of US Special Forces, only to get shot straight through the door. To make things worse, one of them drops the grenade he was holding, which proceeds to bounce down the stairway to where the rest of the Cartel mooks had been standing. Unsurprisingly the US forces easily escape in the confusion.
In one Elseworlds comic, his pirate incarnation does it to a shark. Just because.
The cool factor is in no way undercut in Batman: Year One when they show all the preparation that goes into his entrance, including tranquilizing the guards, cutting the power and setting up the explosives and fog machines by the wall.
All of the heroes in Sin City do it at one time or another. The most notable example would be Marv in his very first appearance. The police are knocking on his hotel door. They know exactly where he is and are demanding that he come out... and yet he still manages this.
Captain America, having come back from the dead, makes his presence known to Norman Osborn (wearing an Iron Man armour) by hurling his shield at him, shown in slow motion as the shield reflects off of Osborn's faceplate.
In the Jackie Chan Adventures fic Queen Of All Oni, Jackie and Tohru fall through the roof of the basement of Shendu's palace, temporarily disabling Jade and knocking Hak Foo out completely, BY ACCIDENT!
Forward, a Firefly fic by the same author, has two of these in the "Silver" story arc, with the first going to River, ambushing a manvia refrigerator. Later, Simon gets one when he punches out an aristocrat while he's threatening Inara.
Don't forget Jayne running into a giant brawl in the cargo bay while on fire.
Mana seems to be fond of this trope, having used it in Chapter 41 of Shinji And Warhammer 40 K after riding a building that was being dropped on the enemy's head. Even had a speech ready afterwards:
"A HERO ARRIVES IN THE NICK OF TIME!" A boxy red shape punched out to stand on top of the tilting structure's roof. "A hero strikes when least expected! The enemy of all that is good, the ones who wants to destroy this world that is made of love! And peace! Will never escape from justice! Specially in the moment that he feels safe, he will know! There is nowhere to hide! The name for this! IS DYNAMIC ENTRY!"
In Dragon Age The Crown Of Thorns, dwarven commoner Faren Brosca interrupts the No-Holds-Barred Beatdown that the final form of the Sloth demon was administering to everyone else at once, including the protagonist and resident One-Man Army blood mage Alim Surana, with a Flash Step and a roundhouse kick to the face, followed immediately by another Flash Step and a descending axe kick that drove the demon into the 'ground' so hard that it left behind a huge crater and blew a huge dust cloud into the air. And it all happened in little over an instant.
And Shadow crashes through the ceiling of Brainstorm's lair. Calvin and co. follow suit a bit later.
A Growing Affection has Choza Akimichi being saved by a literal one of these, from the Deva Path of Pein, as part of a chapter cliffhanger, leading us to believe Team Gai has come to the rescue. The next chapter reveals it was Naruto's jump kick, and has Kakashi lamenting that he has asked Naruto not to do that.
A vehicular example from Commando, as Matrix is in dire need of guns before riding off to save his daughter, he busts into a shop by driving through the front door with a bulldozer.
Similar to Commando, Jackie Chan drives a big earth mover truck into the Big Bad's house at the end of Mr.Nice Guy, effectively bringing the whole building down.
At the end of Lockout Snow arrives suddenly to grab Hydell's knife in his hand (OWCH!) before he stabs Emilie and then procedes to punch Hydell in the face.
Played straight (heh, heh) in Jackass 2, "The Diamond Robbers." No, they didn't hit anyone, but Entry has never been so Dynamic for these office rats!
Played even straighter (heh-eh, heh heh!) in Victor/Victoria when loyal Squash bravely, uh, busts in on King Marchand and "Count Grazinski" in flagrante delicto.
Either reminiscent of or the inspiration for Rorscharch's Dynamic Fridge on poor Moloch, Kato (having been instructed films ago to keep ambushing Clouseau at any opportunity as training) managed to get the drop on the Sellers character by attacking from the icebox. Being rather cold by then, he was a lot more savage than usual..
The steroid-popping Dragon from Ong Bak ambushes Tony Jaa this way when when the hero was about to go after his boss.
This is only fair, as Tony Jaa is a grandmaster of this technique and uses it in both Ong-Bak (outside the cave), and even more impressively in Tom Yum Goong / The Protector (party club on the river).
Referred to as "the element of surprise" in the Inspector GadgetMovie. The surprise, in this case, being the Gadgetmobile slamming into the back of Claw's limo.
In Equilibrium, Preston makes his entrance by having two SWAT team members shoot the hinges off a door as he leaps at it, timing it so that he kicks in the hingeless door and slides into the pitch black room, into the midst of a dozen or so men armed with automatic weaponry. They stop shooting, the whole room goes dark, and for a moment we think nothing's going to happen.... then there's a 30 second scene comprised entirely of muzzle flashes illuminating Preston blowing all of his enemies away with no effort whatsoever.
Hilariously subverted in Memento, a movie otherwise steeped in serious Film Noir. Leonard knocks on a guy's hotel room door, and kicks the door open and knocks him out as soon as he looked through the peep-hole. Then Leonard looks at the unconscious man, and realizes that he just kicked in the wrong door.
Scorponok gets a very effective one of these in Transformers: Revenge of the Fallen. It makes an awesome return for the character, who hadn't been mentioned since disappearing in the first film, but doesn't end well for him.
That scene was actually a Double Dynamic Entry, as just seconds before, Jetfire took out (a?) Mixmaster with one.
Yor: The Hunter from the Future has quite possibly the most awesome example of any Dynamic Entry in the history of fiction: After the Damsel in Distress gets captured by a group of purple cavemen and dragged to their cave, Yor decides to use the instantly frozen-in-rigor-mortis carcass of a giant bird lizard he killed not five minutes ago to glide in through the enterance to their cave and dropkick a purple caveman in the face, all while his theme music blares up to inform the audience that yes, Yor is, in fact, the man. Just watch it for yourself.
Brannigan (1975) opens with John Wayne kicking down the door and saying "Knock, knock!"
In the Fist of the North Star Live Action movie, this occurs to great effect. As a pair of Zeed's thugs take a woman into a house to be raped, Kenshiro kicks through the freaking wall and dislocates a thug's jaw, knocking him out, in the funniest moment in the movie.
In Resident Evil: Apocalypse, Alice enters a church on a motorcycle...through the stained-glass window twenty feet off the ground. How she got there is never explained, but her entry results in dead monsters.
In Kamen Rider Decade: Final Chapter, after being overwhelmed by Doras, Decade, Diend, Kivala and Kuuga receive aid from their Alternate Universe allies (the rest of the Heisei Riders). They all come in attacks blazing, destroying all of Doras' monster mooks in the process.
Lucky Number Slevin features The Fairy's bodyguards, ex-Mossad agents who enter the scene after a panic button has been pressed. Their mission: Kill anyone but The Fairy.
TRON: Legacy. During the Light Cycle sequence, we get two dynamic entries, within seconds of each other. First, Sam is driving his cycle toward another program to get his cycle-stick-thing to him, when suddenly, Clu ramps his LC on top of the program in question, and he just appears out of nowhere. A few moments later, Quorra bursts into the arena in a Light-Tank, and Clu ends up running right into it.
Dynamic Entries are Iron Man's trademark. It's easier to list the times he hasn't done one. Though no matter how often he does it, it never gets old or repetitive. He's just awesome that way.
Thor: You listen well, brother. I... [knocked off the cliff by Iron Man arriving]
Loki: [shrugging nonchallantly and still looking at the spot Thor was just occupying] I'm listening.
Prior to that, Captain America gives us a pretty damn good Dynamic Entry when he jumps in to deflect an energy blast from Loki's staff with his shield to save an old German man who refused to bow before the villainous demigod.
Thor does a couple too. First on the SHIELD helicarrier, when he saves the Black Widow from the Hulk, as he's the only Avenger capable of going toe-to-toe with the rage monster (being an alien demigod and all). During the final battle, he appears on the scene first as bolts of lightning frying a bunch of Chitauri soldiers and then Thor himself descending. Hell, Thor's hammer does this during his fight with the Hulk. Thor summons the Mjölnir and, as soon as it's in his hand, he uppercuts the Hulk with it in slow-mo fashion.
In the Spider-Man novel "Darkest Hours", Spider-Man yells "Boot to the head!" as he swings in and kicks the Rhino in the stomach.
In Sergey Suhinov's Shadows on Mercury novel, the heroes arrive too late to stop the Big Bad from finding and taking a hyper-advanced Precursor ship, which they plan to use to Take Over the World, in the middle of a hazardous Asteroid Thicket. While the Big Bad is chatting with the heroes, a UN cruiser bursts in and launches a nuclear barrage at the Precursor ship before they even have a chance to turn on the Deflector Shields. In short, the only thing the heroes ended up doing is calling for help and creating a distraction.
In The Dresden Files book Dead Beat, Harry Dresden does this for the team of Wardens when he has Sue the T-Rex leap over them and stomp an oncoming car.
In Blood Rites, Murphy does this for Harry, when she kicks one of Lord Raith's bodyguards so hard it snaps the bodyguard's neck.
Rainbow Six does this quite frequently as part of their trademark hostage rescues. Generally, the sequence of events opens with the teams' resident Cold Snipers scoring headshots on any terrorist who's pointing his gun at the hostages. Moments after that come the flashbangs, the detcord ripping open the doors/windows, and Rainbow team members emerging from nowhere (or so it would look like from the inside).
Such is Grand Admiral Thrawn's tactical acumen that he can pull off a Dynamic Entry with spaceships. By using an Interdictor-class ship, which was designed to pull enemy ships out of hyperspace and keep them there, he can jump his own ships in with otherwise unimaginable accuracy. This, along with some judicious use of combat telemetry from other ships, allows his Star Destroyers to revert from hyperspace already firing at enemies they know will be there, who cannot respond in time. Only a few commanders, such as Garm bel Iblis, can keep up with Thrawn's use of the technique, and it's very devastating to the Republic cause.
Ban pulls this as well in an early episode of Tokusou Sentai Dekaranger. Hoji becomes exceptionally depressed over a mistake he made in combat, and Ban, unable to talk him out of it, simply waits for his depression to become a complete distraction before letting loose with "SNAP OUT OF IT" scream and a dropkick.
His trademark entry was averted in a couple of episodes. In one, Jerry's apartment is robbed while he's away, so he starts locking the door at all times. At one point there's a loud thump on his front door. When he opens it, Kramer is on the floor, holding his head. In another episode, Jerry has a woman in the apartment, and again, has the door locked, leading to another loud thump on the door.
In Firefly, Dobson is holding River at gunpoint, threatening to kill her if her brother doesn't drop his weapon...at which point Mal casually walks into the room and shoots Dobson in the eye without blinking. Or even slowing down.
Anna Devane of General Hospital is guilty of this as well. She once repelled through the skylight of her daughter's apartment and when asked by said if she could ever use the door like a normal person, she replied, "Doors are so pedestrian."
Captain Jack Harkness gets one in the Torchwood episode "Kiss Kiss, Bang Bang", after having been away from the team for some time due to circumstances beyondhis control. Gwen, Owen and Ianto have got themselves in over their heads with a hostage situation involving a dangerously high alien blowfish and a terrified civilian, at which point Jack strolls in, shoots the alien in the head and cheerfully greets his team.
In "The Harvest", Luke is about to chow down on Cordelia when Buffy kicks one of his mooks over a railing and onto the stage below. Luke watches him land with a thud.
In the episode "Angel", Things aren't going so well between Buffy and her fan club. As the leader of the Three is going for the kill, Angel suddenly yanks his hair from behind and punches him in the face.
Angel: Good dogs don't... [socks vampire] bite!
In the Season Two premere, Xander grapples with a vampire in a losing effort until a hand yanks the vamp away. We then see the vamp get pummeled by someone in a shiny micro-mini.
Buffy: Miss me?
While Angelus is busy with her Watcher, Buffy swoops out of nowhere and judo kicks him in the back. ("Passion")
Angelus:(to Giles) All right, you've had your fun, but you know what it's time for now?
Buffy: My fun.
Perhaps the most famous example in the Season 2 finale. A Sunnydale cop, so nonexistent in previous weeks and so very prevalent in this one, jumps out and tells Buffy to hold it right there. Suddenly, the gun gets kicked out his hands. Spike pops out of nowhere, slaps around the cop and kicks him into the hood of his car, knocking him out.
Spike: "Hello, cutie."
In the same episode, Angelus readies himself to free Acathla as his acolytes look on. Buffy enters quietly behind one of the henchvamps and cleanly decapitates him. O hai!
In "Consequences", Faith is straddling Xander in her bed and about to strangle him. She hears a sound and looks over to see Angel swinging a baseball bat before the screen goes black. Ow.
The first time by Gibby and Guppy and the second time by Mrs. Benson and T-Bo...on a MOTORCYCLE.
In Castle, being a cop show, doors suffer much abuse. Castle is thrilled when he finally gets to break down a door himself (albeit ungracefully) and save Beckett.
In Kamen Rider Fourze, this is Meteor's method of entry into battle. He transforms somewhere, then flies into battle in a Sphere of Power that explodes when he appears, causing damage to anything in close proximity.
This is actually his transformation sequence. The Sphere of Power that appears when he transforms carries him off and he drops in on the enemy in an explosion; you don't see his full suited form until it dissipates. They don't call him Kamen Rider Meteor for nothing. It is extremely rare for him to still be standing where he was when he changed.
Skyrider, the main character from (what else) Kamen Rider Skyrider, does this quite often crashing his motorcycle, the Sky Turbo, through walls, windows and anything else. It even has its own name: Rider Break.
In Let's Go, Kamen Riders, every Rider ever hops on their bikes to join in the All Rider Break to take down the Great Leader once and for all (which really means "until the next teamup," knowing the Great Leader.)
In Kamen Rider Wizard, Kosuke, aka Beast, is fond of leaping in and attacking the enemy once before suiting up. In old-school Rider Kick pose, even!
Many, many backstage brawls start this way. One wrestler will be either conducting an interview or be involved in a (usually unrelated) conversation with another wrestler when he/she will suddenly be ambushed by the wrestler with whom he or she is currently feuding.
Dungeons & Dragons 3.5 Ed has the 'Flying Kick' feat, which turns any unarmed charge attack into this, along with an additional 1D12 damage.
There's also the Leap Attack feat, which allows a player to combine a Power Attack with a jumping charge to do up to three times their normal damage.
There's also the blood magus from complete arcana who I'd say was the King of this trope. His 'Blood Walk' ability allows him to enter any creature with blood's bloodstream then essentially teleport to any other creature in range (which is a long way, basically a teleport spell). Upon arrival you burst out of the target, forcing a fortitude save and huge damage (though you can choose not to if you're going to an ally). So his dynamic entry is BURSTING out of an enemy's body in a shower of blood from miles away.
GURPS has the Flying Kick and Pole-Vault Kick skills. Flying Kick can be combined with Flying Leap for spectacular entries.
This◊ custom model for Warhammer 40,000 representing a Tau Crisis suit entering play via Deep Strike. It's a shame they can't actually do that in game.
Ork Stormboyz led by Boss Zagstruk can.
the tyranid mawloc can enter play by shooting out of a large blast if his deep strike lands on an enamy (hes also the only deep striker that can be intentionaly placed to deep strike in this situation)
Space Marines usually specialise with this as they usually act as shock troops. However, they usually do it from orbit.
Pretty much any case of a unit arriving on the battlefield via Deep Strike, which can involve teleportation, airdrops, burrowing, or a myriad array of other more outlandish methods. Special mention, however, goes to the Deathwing, designed to arrive en masse and shred the enemy in a hail of More Dakka, and Space Marine Vanguard Veterans, whose Descent Of Angels rule allows them to fall out of the sky and start stabbing people right away without giving them a chance to shoot back.
As of 6th Edition (or before?) there is a special rule, Hammer of Wrath, which is mostly used by jump infantry to bump their first melee attack up to initiative 10 (normally the maximum possible under the rules) when they... jump into the fray. To put this into perspective, even the Eldar don't usually go above 6 except with their fastest units when those are buffed.
Warhammer Fantasy 8th Edition has a few versions of this. The ambush rule, if it goes off right, alows you to place a unit where ever you wnat (like behind the enemie's preciouse cannons); scouts can now be deployed as close as 12 inches from an enemy unit; assassins' hidden rule alows them to hide in their unit then pop out at any time. Because assassins always strike first, they hit hard first.
Fudge Firefight presents us with the following: Glass Dancer: You're a master of leaping through plate glass windows, guns blazing, grim determination spread across your face. Apparently the glass protects you by disorientating enemies, or maybe it deflects incoming bullets, but regardless of its actual function it makes you completely immune to incoming attacks while you smash through it.
Magic: the Gathering just so happens to have a card for this exact purpose, aptly named "Dramatic Entrance". Combos with this tend to err towards the ridiculous.
The move Fake Out is a low-powered move with decent PP that is guaranteed to make the opponent flinch and miss their turn, with the catch that it can only be used if the user has just entered the battle.
This is how Captain Falcon first appears in The Subspace Emissary in Super Smash Bros. Brawl. Those poor Pikmin... *sniff*
On a related note, his Falcon Kick is a great way to introduce yourself in a free-for-all Brawl.
City of Heroes has this in two powers: Shield Charge and Lightning Rod, where you teleport into a group of foes and do a fair amount of AoE damage. Of course, with a fair bit of lag working in your favor, you can queue just about any attack and rush into a group of foes and hit before any of them know you're there.
Most MMOs have a technique for their warrior-type that involves a dynamic entry, they're usually referred to as "charge".
Just about every tag-in in a Marvel/Tatsunoko vs. Capcom game comes in the form of a Dynamic Entry where the character who's getting into the fight kicks or punches the rival (or in Hakushon Daimaou's case, dives into them with his ass headfirst) in their entries.
Super Robot Wars Alpha 3 also gives you the DaiRaiOh's ultimate move Jinrai, which combines this with Hot Wings. While it doesn't look like a real invoking of this trope, there's this last scene on the scenario of the robot's pilot Touma. Big Bad Keisar Ephes tried to attack the ship his girlfriend Minaki is in. Touma gets super furious and then executes this trope immediately, STRAIGHT ON KEISAR EPHES' FACE.
Thane makes such an entry in Mass Effect 2 when he drops from the ceiling and quickly dispatches some mooks before putting a bullet into a corrupt asari businesswoman.
During the attack on the Citadel in the original Mass Effect, Shepard does this using the Ilos mass effect relay connected to the relay "statue" on the promenade, blasting full bore in the Mako and plowing right into a pair of Geth who never knew what hit them.
Geth in the entire series are fond of appearing by falling from a Drop Ship and then dramatically unfolding.
In the third game'sCitadel DLC, an unarmored Shepard and a squadmate are pinned down a by a shuttle full of mercs...until Wrex leaps through a window and elbow-drops the shuttle out of the air. Then he takes the mercs apart with his bare hands (and head).
Nero's first blow to Dante in Devil May Cry 4 was a dropkick. With both feet. To the face.
The dropkick can also be done in-game.
Dante also does one to Sanctus: He just crashes in from the ceiling right on Sanctus' face, then Boom, Headshot.
Touhou's Wriggle Nightbug is sometimes seen in fanworks performing a Dynamic Entry or some other form of flying kick, usually specifically called "Wriggle Kick." (Her Touhou Puppet Play counterparts have two such moves, the one named number 2 being a take on Fake Out.) The technique's origin is not often apparent, but it surprisingly has its roots in the games: while playing as the Magic Team (or Marisa solo) in the eighth game, players can auto-collect onscreen items by going to the top of the screen at any time, where normally it would be limited to when the character is at full power. This is often disastrous when Wriggle descends from the top of the screen for her midboss appearance, leg extended, straight into Marisa's face.◊ As Wriggle is a youkai bug in humanoid form, the Wriggle Kick is likely a Kamen Rider Shout-Out.
There's also Kisume, Stage 1 midboss of the eleventh game, who does the same thing while in a bucket.◊ Considering the fact that Kisume is a Tsurube-otoshi, a Japanese creature that lays in wait for humans and then drop down onto them, this was likely intentional on ZUN's side. Heck, she almost touches the bottom of the screen at times during the fight itself.
Worse than this is Chen, in her appearance in Shoot the Bullet. Usually, the player is encouraged to spend the first seconds before the boss appears stationary, charging his camera. This is usually well and good... except that Chen then proceeds to enter screen by falling like a brick in the exact same vertical line the player spawns at, usually ending with the first-time player eating a catgirl to the face.
This overlaps with Squall's story. The best part is that Squall is all set to fight two powerful end-bosses, and gives a speech about how he'll do it, no matter how hard it might be, if it'll make things easier for his allies, and then Zidane does his Dynamic Entry and tells Squall to stop stealing the spotlight. In fact, it's even better from Squall's side, because, from his perspective, Zidane comes completely out of frickin' nowhere. And, just before he crashes in, Garland turns his head slightly; the poor sap saw it coming (entire English scene starts here).
The scene just before the very first stage of No More Heroes starts off with this: Travis Touchdown drives his motorcycle through the gates of a mansion, leaps into the air with Beam Katana drawn, then, upon landing, the two mooks behind him fall apart in a pile of blood and body parts. Talk about Crazy Awesome.
The Shivans do even better when the Sathanas jumps into the battlefield and melts a destroyer under your escort. Note that FreeSpace does not follow the usual Earth-navy notion of a destroyer as a small ship — destroyers serve as carriers here, and are the biggest military ships in common service (next to the aforementioned and singular Colossus).
The original Mercenaries opens with the player mercenary of choice driving his/her humvee out the back of a C-130. While it is flying. Into a war zone. You then have to power through enemy blockades to reach the Coalition HQ.
Gwendolyn in Odin Sphere does this twice with her diving spear attack, first to save Velvet from General Brigan and later to save her husband Oswald from the infant Levanthan.
Halo 3. Level: The Covenant. Miranda Keyes makes a Dynamic Entry with a Pelican gunship.
In King of Fighters Maximum Impact 2, Chae Lim enters her stage in story mode by kicking through the screen door. And splitting it in two. And leaping into the stage.
A Ragna vs. Jin versus mode match in BlazBlue will open with a Double Dynamic Entry. Both characters enter the stage from the sides with their charge moves, cross pass each other, then the announcer interrupts them to start the match.
Also, in the beginning of Litchi's Astral "Nine Gates of Heaven", she first jumped upwards and vanished, and out of nowhere, from the side of the screen, there she comes lightning fast with a flying kick. If you're hit with it, you're beaten. To add things up, the move can be delayed.
In Tekken 6, Lars has an actual stance called "Dynamic Entry", in which he dashes towards the opponent extremely quickly and attacks them.
Actually, the "Dynamic Entry" move is more of a Flash Step (he just shuffles forward quickly). For a more accurate Dynamic Entry, his running left kick attack (where he heroically leaps up and thrusts his foot in his opponent's face from a running start) is probably a closer example.
Alyx's entrance in Half-Life 2. As Gordon is knocked unconscious by Civil Protection...
Over here! (sound of someone being whacked) No, you don't! (sounds of the cops getting their asses handed to them) Hm.
Assassin's Creed has a kill animation closely related to this trope: Altair runs up to the target, leaps onto him and stabs him in the throat.
A better example is the technique where you jump off a roof onto a guy to knife him.
The hookblades introduced in Revelations give you a technique where you can side behind a guard from a run and sweep him off his feet with your hookblade, leaving him prone and wide open to be finished off easily.
The intro to Freelancer shows a Coalition fleet jumping out of FTL right on top of the Alliance defense fleet, firing even before they complete the transition. Needless to say, the defenders were obliterated before they even had a chance to return fire. A rare case of the bad guys (according to the game storyline) doing this successfully.
In Red Faction: Guerilla, it's almost outright encouraged that you find the heaviest vehicle and drive it into, or sometimes THROUGH the enemy base, as you cannot be hurt while inside a vehicle, the heavier ones can rip walls to shreds, and later ones have weapons like HEAVY ROCKET LAUNCHERS strapped to them for easier Entries.
Call of Duty: Modern Warfare 2 features this at the end of "Takedown" as you chase an arms dealer through a Favela in Rio.
Ghost: He's gonna get away!
Soap: No he's not. (Dives out of a window ahead of the player and tackles the target down onto a wrecked car from the first floor.)
The slow-motion breaches could also be considered this, although in that case it's the player doing so.
Q in Street Fighter III: Third Strike. Here we have a spooky creep in a trenchcoat who doubles as a badass brawler dude, and he just JUMPS ONTO THE SCREEN. Although on the stages that take place in urban areas, his intro is even more elaborate. A group of children run off the screen as Q walks in eerily.
In his stage, Yang leaps into the stage from what, at least two stores above the stage?
Pulled by several charas in Street Fighter IV. Aside of Yang and his brother Yun we have Dan, Guy...
Most Beat 'em Up games feature this: when a player continues (or a second player joins the fight) expect all foes on screen to get knocked off their feet. The norm is not having any visible effect or explanation for the mobs tripping over spontaneously, but certain games do have animations for them, for example, Cadillacs and Dinosaurs has your character respawn after a deadly barrage of rockets.
Kuradoberi Jam in Guilty Gear does this literally in one of her intros, leaping into the screen with a Kiai shout:
"Kuradoberi Jam, tadaima tanjou aru!"/"Kuradoberi Jam, now appears!"
Also, May's hilarious Instant Kill move is basically her grabbing her victim, tossing them to the ground and having them dynamic-entried by the whole crew of the Mayship (including the fat cook, the baby, the pet cat, and Dizzy). See it at 0:40.
Bridget's intro has him rushing into the stage and tripping his opponent to the ground before the battle even starts.He then apologizes for it.
Trauma Team has a rather brutal non-human example when a school bus comes out of nowhere and crashes into the middle of a crowded mall.
Note that this was on The second frikkin' floor. What, did the bus hit a ramp or something?
Splinter Cell: You. All the time. This trope is probably at its height when Fisher can fall onto a guard's head with other guards watching. You'll probably get shot at a little, but hey, the awesomeness of the dramamtic entry is worth it.
In Marvel vs. Capcom, swapping out partners causes the incoming character to make a Dynamic Entry, and assists can be used in a similar manner.
SECTION 8 features the ability to instantly kill opposing players by dropping onto them from orbit when you spawn.
I feel like lightning, and my burden is awesome.
In League of Legends, Pantheon's ultimate, Grand Skyfall, allows him to leap halfway across the map and land with a huge shockwave.
Similarly, Nocturne's ultimate, Paranoia, lets him dash to a target from a great distance.
Rengar's passive ability (Unseen Predator) lets him leap out of bushes and his ultimate's stealth on top of a target.
Amumu has his Bandage Toss ability, allowing him to come flying into the fray from massive ranges while stunning his target and often setting up his mass-rooting Curse of the Sad Mummy.
Vi's main attack and Ult are both extremely fast rushes, the Q can go through walls, allowing for some very effective ganks, and her ult is followed up with a Meteor Move that does damage and stuns. Fitting, considering she's so hot blooded she fights just to fight.
After rescuing Kotone from a group of thugs at the end of Day 1 in Kenka Bancho: Badass Rumble, Aya "introduces" herself to you this way, leaping to Kotone's defense against entirely the wrong thug.
It's also possible to use the zipline to kick mooks in the chest and one challenge has you combine this with Destination Defenestration for extra awesome.
The sequel, Batman: Arkham City, has an early mission in which you must subdue a half dozen armed mooks without letting any of their hostages die. The entire encounter largely plays out as a Tutorial Level teaching you all of the 4-5 different ways that you can do this to take out mooks without being seen.
The first technique is used when falling from a dangerous height. If augmented, the Icarus Landing system will activate and cover Adam in a ball of electricity that protects him from falling damage. While falling the player has the option to make Adam smash the ground which releases a shockwave that staggers anyone nearby. Not only is this extremely flashy, but it also creates some extremely funny gameplay moments.
The second technique is used on breakable pieces of wall where Adam can punch his way through using the armstrenght augmentation. If a Guard is positioned behind the wall Adam will snap his neck in the process.
Since the switch to the Frostbite engine, the Battlefield series makes this possible with explosives and vehicles.
Anghel Higure from Hatoful Boyfriend seems to be in love with barging in through glass windows whenever he wants to proclaim something about Edel Blau, demon spores, or his Crimson Breast acting up. The protagonist swiftly becomes accustomed and once responds to the sound of breaking glass with "Hi, Anghel!"
If you're on Sakuya's path then you can be invited to a party which is literally crashed by Oko San, who breaks through a window in search of pudding.
Near the end of the tutorial level of Dark Souls, there's a ledge you can use to drop down on the Asylum Demon with an opening attack. This makes the battle a fair bit easier... but if you wait too long to go through with it, the demon will fly up and smash the ledge — this is frequently instant death for characters this early in the game, and severely damaging even when it's not.
In one of the trailers for the Updated Re-release, Abysswalker Artorias does this to a monster by jumping down and impaling it with his BFS.
In the reboot of Syndicate Agent Tatsuo makes his appearance teleporting in and giving Miles a Boot to the Head. Agent Ramon shows up by jumping in and doing the same after you first open a door to a seemingly empty corridor. You are also instructed at several times to crash through things, which may surprise a mook on the other side.
Knights of the Old Republic and The Old Republic have this in the form of a jedi/sith warrior technique which involves selecting a target, leaping a huge distance all the way to said target and causing some delightful damage.
This serves as a gameplay element in the Mana Khemia series. Party members who are out of battle can swap in via support attack at the end of another character's move, and each character has unique upgrades to make an even more impressive entrance. Alternatively, they can swap in defensively for a Big Damn Heroes moment.
Mortal Kombat: Shaolin Monks features this toward the end; Raiden intervenes when Liu Kang attacks Kung Lao, stating that Shang Tsung has been manipulating the duo into empowering him. Before he can reveal exactly how Tsung was doing this, however, he is blasted by Shao Kahn, who has just come into the hallway.
The Quartz Dragon in Phantasy Star Online 2 makes its appearance in field maps by crashing from the sky into the ground head first at a ridiculous speed. More often then not, its landing point ends up being directly on top of you, and it can easily one shot the less defensive classes in this manner, which means that if you suddenly see a boss indicator show up on the edge of the radar in areas where it can appear, dodging/guarding might be necessary in short order.
Tower of God: Yuri introduces herself to Baam by jumping down on his face.
In those rare moments of Exterminatus Now where Eastwood gains a sudden burst of competence, you get this. Extra points for this strip being actually called "Dynamic Entry".
Toyed with in A Loonatic's Tale. Tiny Doctor Qubert bursts into the scene shortly after a (very efficient; just two words!) verbal drubbing from an ill-tempered coworker declaring that "DREAMS LIIIIIIVE!" In the panel prior, easily missed, is the tiny "click" of him tripping the latch. The authors missed the opportunity for the "thump" of his first attempt.
In Super Mario Bros. Z episode 7, Metal Sonic at first ambushes Mario and Sonic in the tunnels this way (or he would have, if Mario hadn't heard him), but then in his appearance in the Minus World he delivers a standard villainous speech before attacking. Then invoked again when Shadow suddenly appears and pummels Metal Sonic before stealing his Chaos Emerald.
Wouldn't Mecha Sonic's massive haymaker on Mario have been a Dynamic Entry?
Luigi sort of gets one of these in the short clip from the unfinished episode 9, when he uses his Tanooki Suit powers to break out of his petrification offscreen, before WALLOPING Basilisx with his hammer to save the weakened Mario. View here.
A scene in The Lazer Collection 3 has Detective Randall coming out of nowhere, hitting Dr. Octogonapus with a flying side kick - a rare case of a Dynamic Entry being countered by another Dynamic Entry.
LoadingReadyRun: In the "Meatshroom" episode of Man Cooking, Morgan opens the segment by very calmy saying "Hello, and welcome to another edition of Man Cooking.", at which point Paul runs in from off-camera and slaps him while shouting "MANLY!"
In the same series, Chapter 9, after a three season absence, Tex proceeds to make her return by smashing up a metal door in front of a terrified group of Reds not knowing who's on the other side, before she kicks it completely clear of the frame. The next episode is a 7-minute long Curb-Stomp Battle.
Fly into the assembly hall in a jet fighter, so low that the crowd runs for their lives. Leap dramatically from the fighter and deliver a Pre-Mortem One-Liner immediately before vaporizing that bastard that really, you should have shot years ago. Dare any of the crowd to make something of it. What'd he say his name was? GALVATRON!
From the same production: The Dinobots busting in to break up Hot Rod and Kup's aborted trial and flattening the "bailiff" in the process. Overlaps Big Damn Heroes, as they save Kup and Hot Rod from being devoured by lots of sharkticons.
Slag: [to bailiff] Excuse me!
Optimus Prime makes his first Earth appearance in Transformers Cybertron this way. Thundercracker is circling for another strafing run on Landmine and the human companions. There is a dramatic glint right above the trees. It turns out to be Optimus in flying fire truck mode. Saying "I hope you don't mind if I butt in!", he rams Thundercracker, and chases him into a canyon. The end result is that Thundercracker runs away after having his own missiles blown up in his face.
G.I. Joe: Renegades: Being a voiceless ninja, Snake Eyes' method of saying "hi" is either suddenly appearing behind you, nearly giving you a heart attack, or a sudden roundhouse kick to the face, depending on how much he likes you.
Batman in Young Justice, doing what he does best in the pilot episode (and in his first appearance) and later in "Downtime".
In The Lion King, the hyenas chased Simba and Nala into a corner, where Simba attempted to chase them off with his "roar". They laughed and encouraged him to do it again. Only this time, it was someonetheydidn'texpect.
Spike gets a couple on Twilight Sparkle in the "Feeling Pinkie Keen" episode.
Gerald from Sid The Science Kid does this before the start of Rug Time, but his version of this is usually themed to the question of the day.
One occurs, as a rather glorious example that predates the trope namer Naruto, near the end of Don Bluth 's 1989 classic, All Dogs Go to Heaven, provided by the Big-Lipped Alligator himself, King Gator. As Carface, the gangster pug, corners Charlie at the edge of a burning pier in an attempt to murder him for stealing Anne Marie, a little girl who can communicate with animals, and exploit her gift at Carface's expense to win it big at animal-related sporting events (It Makes Sense in Context), King Gator, who was last seen in a very bizarre, show-stopping musical number, comes charging out of nowhere, reprising the aformentioned song as he barrels into the support beams, causing the dock to sway and Carface to sink and be at the mercy of King Gator.
King Gator: (singing)AAAAAAAAAAAAAHHHHHHHHHHH~!Let's makeMUSIC TOGETH-AAAAHHHHHHH~!(rams headfirst into dock, causing dock to sway and Carface to fall in the water)
In the Rainbow Magic movie, Jack Frost does this... which the goblins promptly ruin.
In an IRC channel, a Dynamic Entry can be performed by an op that enters a room and immediately kicks someone.
The usual tactic for ambush predators such as big cats and crocodiles. The animal uses stealth to get as close as possible to its prey to minimize its escape. At the right moment, it bursts forward for the kill.
A useful strategy for military or police forces who need to enter a building occupied by bad guys. Often preceeded by a "flashbang" (a kind of grenade that makes a lot of noise and a bright flash to disorient your enemies) or sometimes just by blowing a hole in the wall using explosives, a technique known as "mouseholing". Everything mentioned as criteria for Dynamic Entry is also vital to military and police success, since a defensive position is pretty much always at an advantage over the attackers, thus properly utilizing speed, surprise and violence is necessary for a clean and effective sweep. It's not just that, however...
I don't know whether anybody actually does this, but it seems that an effective variant might be produced by subverting There Was a Door. Blow a hole in the wall, toss in a flashbang, wait for the bad guys to start shooting through the hole, and bust in through the door instead.
Waste of time. That "Speed, Surprise, Violence of Action" mentioned in the topper is the US Military's bywords for dynamic entry. While that suggestion may be effective, it takes time, which in a fast clearing situation, you don't have. To the point that if you're mouseholing, you don't even use a flashbang, just use the surprise of the wall breach and unexpected direction. The actual subversion was practiced by the Marines in Fallujah, where the SAW gunner would simply figure-eight the door, then open it, and do the same to the room. Again.
