Crossovers
- How Firefly appears before Rainbow Dash and the Talon squadron in Ace Combat: The Equestrian War. Rainbow makes one of her own by the end of Chapter 12.
- Rainbow does this again in the sequel, using her Sonic Rainboom's shockwave to get a One-Hit Polykill on an unfortunate group of enemy fliers.
- In Amazing Fantasy, All Might is introduced by coming out of nowhere to punch Prowler down the street while she has Mount Lady held hostage.
- Boldores And Boomsticks: Absol first appears when she jumps through a wormhole and decapitates two Grimm at once.
- Maito Gai — The Trope Namer himself — says this line word for word in Connecting the Dots when he saves Mr. Terrific and Green Arrow from being killed by Bane by introducing the guy to Primary Lotus.
- The King of the Monsters himself does this in Chapter 7 of the Godzilla/Evangelion crossover Hail to the King. Just when it seems that Gaghiel (which is now a kilometer long Eldritch Abomination) is about to smash the aircraft carrier the cast is on, Godzilla suddenly leaps out of the water and shoulder-checks the Angel in the jaw, shoving it away from the carrier and knocking out more than a few teeth.
- Harry Potter and the Natural 20: Invoked by name by Milo. In a chapter titled 'Dynamic Entry'. In which Milo dives from the clouds, uses dimension door to teleport into the Dursley's living room, and promptly vaporizes their table.
- In If Wishes Were Ponies, Twilight introduces herself to the Hogwarts students and staff by flying in through the ceiling of the Great Hall and landing on a table hard enough to crack it. This is followed by her calling Philomena the phoenix (a bird so rare in the Wizarding World that many consider it revered) a brat. Also demonstrates how, while Harry loves his foster mother, he wishes she wouldn't be so impulsive when it came to learning about the Wizarding World.
- In Incarnation of Legends, Oryou spends the first arc dealing with monsters on the outskirts of town with the Hachiman and Amaterasu Familia. When she enters the final battle of the arc, she crashes through the ceiling, interrupting all the fighting present.
- In Kyon: Big Damn Hero, Kyon uses one of these when rescuing Tsuruya who was being attacked by Yakuza. When she describes what happens to the others later, she references this trope by name, telling Haruhi that Kyon has "an awesome dynamic entrance!"
- In the Bialya mission of Life Ore Death Ferris does this when she sees two jeeps and a tank chasing two teens, combining speed, weight, and a jump off a cliff to wreck a jeep.
- Hachiman provides a picture perfect entry in Yukinoshita's Sidestory in My Hero School Adventure Is All Wrong As Expected. Surrounded by villains on all sides, Yukino appeared to be in dire straits before Hachiman glided down on a thermal updraft from the burning buildings surrounding them to deliver a devastating blow to the biggest villain he saw...before promptly coughing his lungs out from smoke inhalation.Hikigaya Hachiman, the man with a Quirk for every situation, had unsurprisingly managed to take flight and come to my aid. For a second, he was almost frozen in time, cape billowing behind him and a fierce glare as he looked down at the villains, who took a simultaneous step back when they saw him.[...]And then he pulled his mask down, bent over, and started to cough violently. Oh, right, everywhere else was covered in smoke, wasn't it?
- New Stars: CT-5599 (or Maxx) introduces himself to Marcus and Ty Finn by jumping out from behind a crate and shooting the Krill soldier who was about to kill them.
- In Origin Story, the reason Alex Harris gets to toss Sentry through a sliding glass door in the first place is because he crashes through the roof of her bedroom to attack her. Too bad for him she saw him coming.
- Peter Parker Needs A Hug: Upon his arrival in Gotham, Peter Parker tries to stop a criminal beating an old man. The fight seems to be going in the wrong direction (as Peter can't reveal his spider powers) when Red Hood shows up, announcing his arrival by shooting a gun in the air and jumping to the ground from a fire escape.
- Renegade: The Alternate Universe version of Garrus Vakarian doesn't seem to have any other way to enter a room except by introducing himself with over-the-top violence. For example, if he needs to burst into a warehouse filled with mercenaries, he does so by crashing through the wall with a cargo transport, and if he needs to apprehend a wounded, unarmed mercenary, he does so by blowing up his car with a tank.
- The Secret Return of Alex Mack: "Action Girl" makes her public debut by diving from a helicopter at five thousand feet, using a parachute that's just enough for her to land safely with her enhanced physiology, through a window that she shoots out just beforehand, and doesn't even stop to dust herself off before leaping after Bane.Hanna: HE IS MINE!
- Shinji And Warhammer 40 K: In Chapter 41, Mana uses it 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!"
- The Spectacular Spider-Man: Lost in Gotham: Two in one chapter: when Tim and Duke are kidnapped for ransom, Spider-Man goes to save Duke while Red Hood goes to save Tim. Spider-Man punches down the door to Duke's cell and scared the urine out of the person guarding him (while Duke thought it was awesome). Red Hood's entry isn't as grandiose, but just as effective: he jumps in through the open window and points a gun at every one in the room who isn't Tim.
- The fic Spider-Ninja has three:
- When she saves Avengers Tower and Agent Coulson, Petra swings in and kicks a robot in the face (doubles as an Incoming Ham moment)
- Baxter Stockman announces his arrival to the warehouse fight by shooting at Mikey after crawling out of the floor.
- After being kidnapped, Donatello enters a fight by back flipping into the building through the window. Doctor Octopus one-ups him by ripping open the ceiling, jumping down (landing tentacles first) and threatening every Dragon in the room with a buzz saw.
- The Green Goblin captures the Shredder with a giant magnet (causing his metal armor to stick to it) before he flies into the warehouse through a window while flying his glider.

- In Buffy the Vampire Slayer/Supergirl crossover The Vampire of Steel, two vampires are trying to gun Buffy down when Supergirl barges in and pummels them.All that went through her mind the instant between the click and the sound of breaking glass.
Sunlight streamed in through a broken window and torn draperies. The two gunmen leaped back, avoiding the rays. A speeding figure was already inside the hall. Buffy saw a blur of blue reaching out to the guy who had been behind her, tearing the gun from his hand, compacting it impossibly into a small sculpture of twisted metal, and backhanding him so hard he somersaulted down the hall. - In Wonderful (Mazinja), when Taylor bursts into an alley to save her friend Emma from a group of thugs, she does so by falling from a rooftop and kicking the nearest goon in the face.Her gaze turned elsewhere as she saw a glint of metal. Another of the men had pulled out a gun, aiming it at the scuffling girl. Emma tried to find her voice, to cry out a warning…
"TORYAH!"
—until a second figure, in a bright red hoodie, fell from the rooftops to kick the gunner in the face. The man staggered, spinning in place, as the interloper landed in a crouch, and rose with an uppercut, fist covered in red light.
"TOH!"
The fist connected, and the gunner did a flip in the air, before crashing back down against the floor, face first.
- Calvin and co. bust through Thunderstorm's lab's entrance at one point in Calvin & Hobbes: The Series.

- At the climax of Hellsister Trilogy's second arc, Darkseid has just struck down the first wave of heroes when Supergirl suddenly flies into the battlefield and smashes into Darkseid.Dev, Kal, Captain Action, Action Boy, the two Flashes, and Joanie Swift were lying on the floor of the chamber as if they were dead, and Darkseid’s eyes were blazing red.
He’d gotten them. He’d nailed them with his Omega Effect. Even the super-speedsters among them, he’d hit.
Darkseid had enough time to hear a scream of terrible rage before a freight train in blue, yellow, and red hit him and smashed him into a wall, and halfway through it.
- 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.
- What If Gine Went With Goku to Earth?: At one point, Raditz Instant Transmissions in to defend his mother from Cell, punching the android in the jaw and sending him flying into a mountainside.
- Forward (Peptuck) has two of these in the "Silver" story arc, with the first going to River, ambushing a man via refrigerator. Later, Simon gets one when he punches out an aristocrat while he's threatening Inara. Also Jayne running into a giant brawl in the cargo bay while on fire.

- Alucard from Hellsing Ultimate Abridged gets several:
- In Episode 4, Alucard must make his way onto a fully-armed battleship in the English Channel. The guns are hot and the waters are mined, leaving only one angle of attack: above. Alucard proceeds to crash an SR-71 Blackbird moving at supersonic speed directly into the bridge to the appropriately badass tune of AC/DC's "Shoot to Thrill".
- In Episode 8, after having been stranded on the aforementioned battleship, Alucard makes his glorious return by steering the battleship back into London, jumping a few hundred feet into the air, and landing directly between the Nazis and Catholics. All to his tune of "Ready to Die" by Andrew W.K.
- In For the Glory of Irk, Carrius feels the need to keep doing this:
- He makes one to the confrontation between Lor and Dib and the Irkens by kicking open Lor's door. Lor complains about it, since he's the one who has to pay for damages.
- He does this again later when bursting into Lor's trial. Dib Face Palms at it, as this was clearly unneeded.
- In 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 by pure accident.

It is about to blast Rei when Unit 03, piloted by Shinji and Asuka, slammed on it from behind, knocking it to the ground. Shinji and Asuka declared straight after: "Get away from my friend".
- Doing It Right This Time: Mari Makinami has participated in two of these, only one of which was actually her idea but neither of which have worked all that well for her. Particularly the second, intentional one versus Ramiel, which wasn't going to end well even if she hadn't decided to combine it with headbutting it.
- Nobody Dies has Mana and Jet Alone Prime interrupt the battle with Ramiel by executing one of these from orbit.
- Yamato in Crossed Lines announces her arrival at Loguetown by attacking Luffy, only to get interrupted by Nami who demands they not use haki in their clash, lest they destroy the town.

- Pokémon Reset Bloodlines features examples of this during the WhamEpisodes:
- In Chapter 23, Ash reaches the Gringy City's Power Plant control room, and ends up frozen against a wall. After a tense and rather revealing chat with Belladonna, Charizard (who has just evolved) smashes through the locked door, allowing himself, Pikachu and the others to come in and rescue Ash.
- In Chapter 34 there's an even bigger one. When Ash is kidnapped by Sabrina and forced to fight his way through her hordes of Psychic-types, Dexter initiates a plan to teleport every single Pokémon Ash has at Oak's ranch to level the playing field. They break through the ceiling and quickly join the fray when Ash and his current active team are reaching their limits.

- Deconstructed and reconstructed in Price of Blood. Taylor attempts to make a dramatic landing in her new Powered Armor, hitting the pavement on one fist and one knee — but while she does indeed make an impression, she also damages her knee and the suit. Amy later tells her that Glory Girl had to practise that move for weeks to get it right, and Armsmaster agrees that it can be useful to spread shock and awe, but that you need to know how to pull it off without damaging anything.Amy: Because armour or no armour, you’re still smashing your knee down hard enough to crack concrete. There’s a reason most people who do it are Brutes. The Tinkers who do it in power armour always have padding.
