A Manga/DetectiveConan FanFic by Tropers/MagicConan14 that can be read [[http://www.fanfiction.net/s/8111716/1/Legacy here]]. First published in 2012, this fic has a bit of a mystery at the start and eventually becomes a fantasy fighting story. Its real name is ''Legacy'', but due to its name being quite common in the fanfiction search engine, the alternate title is used here.

Toichi Kuroba, as most Manga/DetectiveConan and Manga/MagicKaito fans will know, is dead already. However, [[WhatIf what if]] he was still alive? That's what this fic attempts to answer.

Through Toichi's 'will', Kaito receives a clue as to where his father is, and ends up dragging Conan and Heiji into the mess because of a special...trait...the three of them share: magic. Not enough to be up to scratch with [[FanFic/TheMysteriousSchool The Mysterious School's characters]], but still enough to pull off a decent fight. (Note that the word 'legacy' is used in-universe for said magic.)
!!''Legacy/The Three Legacies'' contains examples of:
* CallingYourAttacks: Zigzagged. The moves' names aren't used in battle at all, but it's revealed after the first battle that the moves do have names. Other than the author using the names in the description of battles, they have no use.
* ClothingDamage: The author has some relish in pointing out this for Kaito:
---> "...the katana that had made its way through [Kaito's] iconic suit had ignited and burnt not only the costume, but the person inside it as well."
* ChromeChampion: Conan - he can turn himself (and anything he touches) into steel.
* DeathDealer: Of course, this is the Kaito Kid we're dealing with in this fic. But there's a catch: [[spoiler: the ammo is fueled by magic, allowing the results to be more damaging than usual]].
* DishingOutDirt: [[spoiler: Sera.]]
* FakingTheDead: If Toichi didn't die from the 'magic accident' in Magic Kaito canon, then he would have faked it. Simple as that.
* FlamingSword: Heiji can do this with Sword Dance, although the sword doesn't actually have flames surrounding it all the time.
* [[spoiler: {{Flight}}]]: Conan's legacy gives him the ability to do this.
* HowDoIShotWeb: Conan struggles a little bit with his second legacy.
* MakingASplash: [[spoiler: Subaru.]]
* NighInvulnerability: Kaito has a legacy called 'Immunity'. [[CaptainObvious Like it says,]] it demonstrates this trope by allowing him to not get hurt too badly in any fight.
* NoSell: Water against Conan's Iron Defence.
* PhantomThief: The Kaito Kid. Both of them.
* PlayingWithFire: Heiji's legacy consists of two powers that have this trope. See FlamingSword for the first. [[spoiler: The second is making shields out of fire.]]
* ShoutOut: To ''Literature/IAmNumberFour'', by using the word 'legacy' as an alternate name for superpowers/magic.
* SignatureMove: Kinda unavoidable since there's a limit on moves.
* StealthPun: Room 1412 from chapter 3. [[ItsALongStory You don't really need to know the specifics to get that one]] if you know the origin of Kaito Kid.
** The moves' names are Pokemon moves which do roughly the same thing as their in-story counterparts.
* [[spoiler: WindFromBeneathMyWings]]: Conan stops a speeding bullet by using this trope. However, said bullet was made to be harmless, so if he got hit, it wouldn't be too bad.
* [[spoiler: WingedHumanoid]]: Conan's legacy allows him to become this.
