Dodge, duck, limbo dodge, jump, throw the trash can, drop the vase, spill the oil slick, slip and make a hit, and win without even throwing a punch. All in a day's work for Improv Fu. A character's fighting style isn't so much as fighting as it is making up new and ridiculous ways to combat their opponent. Perhaps they don't like violence, or perhaps they never learned Kung Fu, or perhaps they just can't catch up. Either way, they find a way to be useful. Improv Fu tends to involve quick tricks, trips, traps, a lot of dodging, and heavy implementation of objects or the environment available at any given moment. Sometimes the character essentially blunders through combat. Most of the time Improv Fu is played for comedy. May lead to Improbable Use of a Weapon if they find one they don't know how to use. If The Strategist finds himself in a situation where he has to fight directly instead of just advicing, he/she may use these tactics. Probably utilized by the Action Survivor as well. It's essentially in-universe Improv for combat, a combination of Indy Ploy and Combat Pragmatist with a lot of Improvised Weapons. This is like an Indy Ploy specifically for fighting and while this is similar to Combat Pragmatist, the Combat Pragmatist usually uses "dirty tactics" to gain the upper hand rather than fighting indirectly to ameliorate their disadvantage. Related to I Know Mortal Kombat. Compare to Confusion Fu. Usually involves an Improbable Weapon User. See also Geo Effects, which involves incorporating the use of the field and terrain to one's advantage or disadvantage (e.g. lava lands, stages with collapsing platforms, etc.)
Examples:Anime and Manga
- Ranma ½: Ranma Saotome has this trope reconstructed, featuring an as-serious-as-it-can-get Anything Goes Martial Arts dojo. While the fighting style has some of its own unique characteristics, Ranma's most distinctive ability is being able to adapt with remarkable skill, something that comes in handy when forced to engage in all sorts of rule-restricted Martial Arts and Crafts.
- Mobile Suit Crossbone Gundam's protagonist Tobia Arronax makes extensive use of this, thanks to his being a very quick thinker. His bag of tricks includes including throwing logs (and enemy machines), using a re-entry pod to disguise his attacks, and in one memorable instance crafting a balloon shaped like a bunch of bananas to distract a group of psychic monkey pilots.
- Fist of the North Star: Jyuza gave Raoh one hell of a Humiliation Conga with a fighting style he invented on the spot. The fight ends with him stealing Raoh's horse, Kokuoh.
- A Certain Magical Index: Shiage's usual method of fighting higher level opponents, which works surprisingly often.
- This is Luffy's main fighting style from One Piece, as he'll use anything available to him so he can win. This cause's his opponents to underestimate him because it, more often than not, looks like him fooling around rather than fighting seriously.
- Minako Aino in Codename: Sailor V has shades of this, having gone so far to weaponize mosquito-repelling incense (to be fair, the youma was a mutant mosquito with an army of the standard insects, so...).
- Dolphin Rider Koishi: Newly-transformed Sirens are advised to just say the first thing that comes to mind when they want to attack.
- Nexus Renegade: Just like his trainer, Tyrogue thinks of his techniques right on the spot.
- To the Stars: Magical Girls are instructed to make up new stuff in combat, since that's how they develop and expand their powers.
- Jackie Chan's characters are all about this. This is because the Chan man loves action but dislikes violence so he uses his own style involving a lot of dodging and using the environment to combat his opponents.
- This is also true for his character in Jackie Chan Adventures.
- Ace Ventura invokes this when in a tight situation.
- Jason Bourne. In The Bourne Supremacy, he beats the shit out of a guy with a rolled up newspaper and blows up his condo with said newspaper when he's done.
- Gamera Vs Guiron: At one point, Gamera swings on a huge horizontal pipe like it's a gymnast's parallel bars.
- Power Rangers has many examples of Improv fu but the most egregious one is that a lot of fight scenes throughout the series features the Rangers fighting grunts in a playground and use the equipment to augment their fighting.
- Mighty Morphin' Power Rangers: Billy the Blue Ranger of the team kind of sucks at fighting, but he manages by using this trope, though by the time he leaves the Rangers he's gotten much better at hand-to-hand
- Power Rangers Zeo: Occurred with Bulk and Skull when they were accidentally sent to a coliseum in another world and they get saved by another warrior, they have to face down a few guards and ultimately, they were able to take them down with the power of bumbling around.
- Power Rangers RPM: Ziggy The Plucky Comic Relief became a Power Ranger by accident and out of desperation so he had no qualifications or skills to actually be a good fighter. Instead he mostly runs around a fight scene dodging enemies or using nearby props as weapons and ways to protect himself. He gets better at hand to hand throughout the series though.
- Kaizoku Sentai Gokaiger's Green Ranger, "Doc" Don Doggoier, is a Lovable Coward who resorts to tricks like hiding in brush, Explosive Barrels, and even breaking out a squeaky mallet at one point. Then there's the episode where he mans up...
- This was comically sent up in the Almost Live! sketch "Mind Your Manners with Billy Quan." Billy and his antagonist would always fight using items around them as stand-ins for martial arts weapons. (In a computer room, floppy disks became shirukens; in a meat market, links of sausages became nunchaku, etc.)
- Martial Law has Sammo Law present this art in its finest form.
- The Everyman Hero from Feng Shui has this as his or her Unique Schtick.
- Spider-Man: Shattered Dimensions: The Spideys mostly rely on their acrobatics and super strength instead of any set form. Well, except for Noire, who somehow knows Chinese Kung Fu.
- Evil Inc.: Muskiday and Haynus ad-lib the latter having a "force field" to explain their "capturing" the alternate Miss Match to Up'n Atom. Only a very short time later, Haynus shows off a working force-field generator...
Haynus: While you were picking up Project X, I got creative...Muskiday: Sly dog.
- In Worm where the setting is filled with people who can shoot lasers and punch through walls, Skitter can control bugs. She ends up doing this a lot, using tactics such as incapacitating an indestructible opponent with the excreted narcotic of a fallen comrade, tricking a massive foe to charge into spider silk frozen in time, and choking a woman to death by filling her lungs with bugs.
- Sokka of Avatar: The Last Airbender a Badass Normal warrior in a group where all the other member have Elemental Powers he is the one who frequently comes up with strategies and plans, including examples like create bombs to try to simulate fire control, spreading perfume to confuse a creature with super smelling senses, offensive use of stink bombs, discovering a moment where the fire nation would lose their powers and plan an invasion on that day, and taking over a fire nation airship and use it as a projectile to destroy other airships... just to name a few. His ability to improvise plans was part of the reason the master Piandao accepted him as his student.
- Half the final battle in the first Kung Fu Panda is Po fighting in this manner, frustrating Tai Lung.
- Krav Maga is a martial art that teaches improvised combat techniques.
