History Main / DeadlyDisc

* The game ''[[https://store.steampowered.com/app/1229580/Disc_Room/ Disc Room]]'' is all about this trope. The primary hazard in all levels are various forms of deadly buzzsaws that come in different shapes and sizes, move in different patterns, and/or spawn even more deadly discs.

* Franchise/{{Gamera}}

* Creator/JetLi's SuperSoldier character in ''Black Mask'' somehow manages to critically wound his former commanding officer by throwing a CD at his neck. Said CD manages to cut into the neck and is halfway in.

** Krillin's Kienzan/Destructo Disc acts like a sawblade that can [[ArmorPiercingAttack cut right through]] enemies that could [[NoSell easily ignore]] any of his other attacks. Only problem is that [[InverseLawOfSharpnessAndAccuracy it never hits anything]] because it's a PainfullySlowProjectile. And in the anime, even this has its limits, as it completely fails to hurt Perfect Cell on a direct hit.
** Frieza has a deadlier version, the Death Saucer. Not only does it cut through anything, but it ''chases'' after the opponent. They require that Frieza maintain constant focus to make them go where he wants; [[HoistByHisOwnPetard so when he loses his focus (and loses track of his own location relative to the disk), his body is sliced in half.]]

** Trash can lids has been used, by Steve Rogers (he was out of costume and had to improvise). Of course, the example he's best known for remains his shield.

* The Franchise/{{Marvel}} superhero Ricochet, who has the superability to throw discs and have them hit whatever he wants.

* ''Manga/BusoRenkin'': [[WeakButSkilled Gouta Nakamura's]] buso renkin is the Motor Gear, a pair of razor-sharp chakrum that resemble gears. When thrown, Gouta can control their speed and direction from a distance, and ensure they [[PrecisionGuidedBoomerang always return to his hands. Gouta is also able to attach the the Gears to parts of his body to enhance his hand-to-hand combat power and his movement speed.

* Creator/GamesWorkshop games:
** The [[SpaceElves Aeldari]] of ''TabletopGame/Warhammer40000'' use "shuriken" weaponry, highly advanced ranged weapons that launch thousands of [[SharpenedToASingleAtom monomolecular discs]] per second.
** One of the unique weapons available to the [[HumanSubspecies Scalies]] from the 1st and 2nd Edition of ''TabletopGame/{{Necromunda}}'' was a discus. Crude discs of sharpened scrap metal, the Scaly propelled these crude weapons with lethal force, hitting with similar stats to a low powered [[PlasmaCannon plasma gun]].

* ''VideoGame/TeenageMutantNinjaTurtlesTheArcadeGame'' had a few levels (notably level two) where there were manhole covers that, once approached, would cause Foot Soldiers to pop out of the sewer and throw the manhole cover at you. It could do a fair amount of damage to the turtls if it hit them, but smacking it with their weapons would send it flying back for a OneHitKill against any Foot Soldiers in its path.

* The the Franchise/StarWarsExpandedUniverse, a small and isolated Force-wielding order called the [[http://starwars.wikia.com/wiki/Zeison_Sha Zeison Sha]] forgoes lightsabers in favor of discblades. The discblades are razor-sharp, imbued with the Force, and usually plated with cortosis to make them resistant to lightsabers. Their fighting style of throwing, guiding, and summoning their discblades makes them experts at telekinetic combat.

* ''Franchise/{{LEGO}}'': the Throwbots / {{Toys/Slizers}} series featured robots that throw disks.

* Franchise/WonderWoman owns several round sheilds, and while she rarely uses them in her guise as a superhero when she is needed to act as the champion of Paradise Island she prooves to be just as adept at throwing them as she is at using her tiara as a boomerang.

* ''VideoGame/StarWarsTheOldRepublic'' has a special fight during their Return of the Gree event. You run through the alien space ship (which is ''completely'' lit up with patches of neon color and silver TronLines) to obtain a "blue torus." Conventional weapons like lightsabers and blasters do not work on the final boss of the mission. you have to take it out with the torus. Yes, you're in a ''StarWars'' game [[Film/{{Tron}} fighting a giant robot with a]] DeadlyDisc. How's that merger working out, Disney?

* ''VideoGame/DestroyAllHumans'': Features the Disc Launcher, which will catch a human on it, fly them into various solid objects to lower the health of the human, and rise into the sky towards the end of its run, exploding and dropping them from massive heights.

* VideoGame/MetalArmsGlitchInTheSystem features "The Ripper", a ricocheting buzz-saw launcher that deals low damage on a direct hit, but is very good at removing enemy limbs.
