Edward Elric of ''Manga/FullmetalAlchemist'' is somehow dropped into the world of ''{{Naruto}}'' like a rock into a pond and tries to cope with it, with not very good results. The fic starts in the "Search For Tsunade" {{story arc}}, and almost immediately during the encounter with Naruto and two Akatsuki members, Itachi and Kisame. After that, Edward is promptly arrested and sent to the Interrogation Department, where HilarityEnsues.

!!Tropes Associated with ''The Truth Decays'':
* AndroclesLion: Edward helps an injured bird that was being [[KidsAreCruel tormented by some children.]] The Bird in question is soon revealed to be a [[TalkingAnimal (talking)]] messenger bird from Suna who was attacked while delivering an important message. [[IOweYouMyLife In return for saving his life]] and his mission, the bird tips-off Edward on the location of his stolen automail.
** DoubleSubverted by [[spoiler: Hinata. She tries to rescue Edward when he is captured by sound ninja. The only reason she is at the right place and time to help is because she'd gone to apologize for [[TheFarmerAndTheViper stabbing him in the back after he had helped her fight off enemy ninja.]]]]
* ArtisticLicense: The effects of laughing gas are exaggerated for RuleOfFunny, and the chapter is all the more entertaining for it.
* BathroomBreakOut: While on the run, Ed runs into team 10 and Gai. Unaware that Ed has just escaped from prison they try to talk with him. Ed excuses himself to the bathroom and never returns, much to Gai's confusion.
** [[SubvertedTrope Edward's second attempt is less successful.]] Ed pretends to take a shower and while the water is running, tries to escape out the window. He is caught almost immediately but pretends to be offended that they would watch him in the shower. Neji points out that he wasn't in the shower, but if Ed wants to be supervised in the bathroom he should continue this behavior. [[ArsonMurderandJaywalking Also he should stop wasting water.]]
* BigEater: Ed and Naruto. In Ed's case, this actually poses a problem for the medical team [[spoiler:after he is critically injured by Itachi]]; Ed's unusual metabolism [[spoiler:plus his connection to Al's body]] means that he processes blood pills and other medications too quickly for them to take effect and requires twice the amount of nutrients and sugars to stabilize his blood sugar.
* BigBrotherMentor: Naruto quickly decides that Ed is one of the coolest people he's ever met, and takes advice from him pretty easily. Lee also has a moment of this with Ed, when he gives him some good advice on dealing with the trauma of having his limbs crushed in the Chunin Exams, as well as his fear of something going wrong in surgery.
* BodyHorror: During an ambush by the Sound 4, Ed is forced to use deconstruction alchemy when one of the attackers tries to behead Hinata; the end result is a gory mess of pulped organs and limbs and a horrified Team 8.
** Naruto comes across a dying ANBU woman. She stops breathing and has no pulse and Naruto knows that he doesn't have time to find a med-nin. [[spoiler: He attempts to administer CPR and her chest caves in, though at that point she was likely already dead.]] It's disturbing regardless.
-->"[[spoiler: He pushed down and her chest collapsed in on itself with a hundred brittle snapping sounds like stepping on a bag of cornflakes]]"
* CavalryBetrayal: [[spoiler: The ANBU team that seemingly came to back up Hinata and Ed appear to members of ROOT and they subsequently turn on them once Tayuya is incapacitated. ]]
* ChronicHeroSyndrome: Ed. He knows it, and it gets him into trouble more often than it pays off, but he can't help it--he's Ed.
** He tries to ignore it, he really does. But every time this happens he starts [[HearingVoices hearing Al's voice]] telling him that he needs to help.
* ClothingDamage: Ed has a transmutation circle in the palm of his left hand that allows him to deconstruct matter, like Scar. So far, he's only used it to destroy Morino Ibiki's coat [[spoiler: and Tsunade's shirt.]]
* ConservationOfNinjutsu: Noticeably averted in [[spoiler:the sound four's]] battle in Konoha.
* CurbStompBattle: Fighting Itachi doesn't go particularly well for Edward or Sasuke.
** A [[LetsGetDangerous properly motivated]] Gai is a nigh-unstoppable force.
* DidWeJustHaveTeaWithCthulhu [[spoiler:The shinigami pays Edward a visit in the hospital after Ed sets off his seal by getting too close to the village wall.]]
* DiplomaticImpunity: Tsunade tries to invoke this by declaring Edward an ambassador of Amestris. In doing so she hoped to grant him amnesty and to protect him from harassment by her political rivals.(i.e. [[WellIntentionedExtremist Danzo]]) [[spoiler: It doesn't work. They just go behind her back and brand him with a Caged Bird Seal.]]
* EvilDetectingDog: The dog at the vet's is "[[LivingLieDetector very good at sniffing out lies,]]" and interrogates Ed when he brings in an injured Nin-bird.
* EyeScream: Ed's use of flame alchemy not only charbroiled Sasuke, the explosion left him temporarily blind.
* FireForgedFriends: Naruto and Edward. After their run in with Kisame and Itachi they are [[AFriendInNeed quick to come to the other's defense]], despite not knowing each other very well. [[FriendlessBackground Naruto]] in particular has become very attached.
* ForWantOfANail. Ed's presence in the ''Naruto'' world prevents Sasuke from being MindRaped by Itachi and from choosing to join Orochimaru. This will ''drastically'' change the course of his life and the lives of many others by extension.
** He also gets Naruto start thinking more carefully when he teaches him not to wave his cash filled wallet around.
* GiantSpider: Kidōmaru's spiders range from the size of pit bulls to oxen.
* TheGlomp: Happy to see that Ed had survived their encounter with Akatsuki, Naruto manages to take down both Edward and Kiba in an enthusiastic tackle-hug.
* GoodCopBadCop: During T&I's initial interrogations Ibiki plays Bad Cop and Anko plays Good Cop.
* GoodSamaritan: Gai is trying to live up to this trope.
* HandicappedBadass: In addition his [[HeavySleeper abnormal]] [[BigEater metabolism]], Ed spends a good portion of the story one-armed due to the research department confiscating his automail. He not only manages to escape his holding cell and sink multiple buildings in his path (including the interrogation center and the Hokage's tower), but also breaks into said research department and holds his own against a chuunin-class shinobi.
* HoneyTrap: [[SubvertedTrope Except not really.]] Anko is more of a {{Troll}} than she is a MataHari but she seems to be thoroughly enjoying herself.
-->'''Anko:''' ''Officially, I can't interrogate him, but [Tsunade] didn't ban personal contact. And if something interesting should slip out in a moment of passion…''
-->'''Kakashi:''' ''I think there might be a flaw in your plan,''
-->'''Anko:''' ''What?''
-->'''Kakashi:''' ''He hates you.''
-->'''Anko:''' ''That just makes it more fun''
** Ino (with some [[StopHelpingMe "help" from Naruto]]) also tries to charm Edward for information to pass on to Sasuke. She hasn't improved from when she tried to seduce Neji during the Chunin exams and the whole thing becomes awkward very quickly.
* ImprovisedWeapon: Ed turns a cigarette lighter into an AerosolFlamethrower/C4 launcher using Mustang's flame alchemy.
* TheInspectorIsComing: The Daimyo's envoy had been invited to the village to assure the Daimyo that Konaha is secure and can still fulfill Fire nation's military duties after Orochimaru's invasion. During the envoy's stay Edward breaks out of the interrogation department and sinks the building. Instead of admitting that they have an prisoner with unknown destructive potential on the lose, they say that [[IMeantToDoThat the T&I department was intentionally moved underground for "security reasons"]] and quietly issue a notice for "a short, one-armed shoplifter who [is] wanted for questioning." The envoy doesn't entirely buy it.
* InspectorJavert
* ItsPersonal: [[InspectorJavert Ibiki]] has had a little bit of a grudge against Edward since the latter broke out of his holding cell and sank the entire interrogation department.
* IShallTauntYou: [[spoiler: Anko's strategy to bait Kimimaro out of his bone forest [[http://naruto.wikia.com/wiki/Dance_of_the_Seedling_Fern]] so that Might Gai can land a hit]]
* LivingLieDetector: The dog at the vet's office. Ed gets away largely thanks to a series of misunderstandings from which everyone assumes (much to Ed's indignation) that Ed is a CrazyHomelessPerson who's escaped from a mental hospital.
* NoSell: With the exception of Itachi's Tsukuyomi, Ed is completely immune to genjutsu. [[spoiler: And even that can only hold him for a little bit before he figures out how to escape it.]]
* OrganTheft: A female sound ninja tells her comrades not to damage Hinata's eyes, they're worth quite a lot of money.
** While not really a original body part, Konoha researchers borrowed [[ArtificialLimbs Ed's automail arm]] without permission, and aren't particularly keen on returning it. Not entirely surprising given the prevalence of, and the attitudes toward this trope regarding actual organs in Naruto cannon.
* PlayingWithFire[=/=]StuffBlowingUp: Ed carves Mustang's oxidation array into a cigarette lighter, allowing him to flash-fry and temporarily blind unsuspecting adversaries.
* PleaseWakeUp: This is [[InvertedTrope inverted]] by Naruto, whose fear of this trope makes him dislike watching unconscious people. He mentions that he drives his teammates and friends crazy "accidentally" waking them up on overnight missions just to make sure they ''can'' wake up.
* PowerTattoo: Ed has a variety of arrays tattooed onto his body in the case his automail is destroyed or stolen.
* PrisonEscapeArtist: Ninja prison cells are designed to detain ninja, not alchemists. The chakra suppression seals that prevent prisoners from preforming ninjusu have no effect on alchemy because it doesn't require chakra.
* ProducePelting:[[spoiler: Tayuya’s auditory genjutsu gets her into an angry shouting match and covered in tomato.]]
* ReasonableAuthorityFigure: Jiraiya and Tsunade.
* RestrainingBolt: A variant of the Caged Bird Seal keeps Ed from leaving Konoha and also hurts him if he tries to tamper with it.
** ExplosiveLeash: while not a bomb, it still preforms this function.
* SirSwearsALot: Edward and Tayuya. [[spoiler: [[HamToHamCombat Then they meet]]]]
* SlaveBrand: Ed certainly interprets the Cage Bird Seal as such.
* SoapPunishment: Happened to Kaemon when he repeated [[SirSwearsALot a few of Edward's choice words about the interrogation department]] to his mother, in spite of (and likely [[LiteralMinded because]] of) Edward's warning that "her head would explode."
* TheSpook: Edward himself, from Konoha's perspective anyway. [[OutsideContextVillain No one knows what he is, where he is from, or what he is capable of.]] It doesn't help that Konoha is feeling very vulnerable and is still unorganized and undermanned after Orochimaru's invasion.
* SurvivorGuilt: Apparently the Promised Day didn't go quite as smoothly as it did [[Manga/FullmetalAlchemist in canon]] and Ed is strongly implied to be suffering survivor's guilt as a result. This is probably the cause of Ed's [[UpToEleven increased]] ChronicHeroSyndrome tendencies. Several people have remarked on Ed's behavior and [[AlternateCharacterInterpretation speculated]] that [[SuicideByCop he wants]] [[DeathSeeker to die.]]
* SymbolSwearing
* SympatheticInspectorAntagonist
* TechnicalPacifist: Ed. Since he is in the Naruto universe, it is quickly noticed and remarked on.
* ToBeLawfulOrGood: Poor Hinata. [[spoiler: She chose law over good]] and spends the next five chapters [[ShrinkingViolet working up the nerve]] to [[MustMakeAmends apologize.]]
* [[spoiler: ThereIsAnother: The "Al Doll" would indicate such. However, exactly who sent it is a mystery, and while Ed initially takes this as a sign that his brother is alive and searching for him, his conversation with the shinigami has led him to believe otherwise. The question of whether it is intended as a [[TheLastManHeardAKnock message]] or as a trap has yet to be answered.]]
* TortureTechnician: Ibiki Morino is the head of T&I. Staff members like Anko, Masao, and Goro might also qualify.
* TreasureChestCavity: Ed uses his automail as a sort of improvised storage space for small equipment, including his lighter and a roll of pre-inscribed transmutation circles.
* {{Troll}}: Ed to Sasuke. ''All the damn time.'' This in addition to an earlier embarrassment quickly installs the Fullmetal Alchemist as Sasuke's new BerserkButton.
** Similarly, Anko absolutely ''loves'' trolling Ed himself.
* WeakButSkilled: While Ed's agility and strength are impressive for someone of his stature, his inability use chakra makes him hard-pressed to keep up with his chakra-enhanced shinobi opponents. On the other hand, his alchemy is more versatile and environmentally adaptable than jutsu which, combined with Ed's resourcefulness, allows him to create improvised weapons and equipment from seemingly harmless everyday items (see [[PlayingWithFire]] above) and control his environment to gain the upper hand (such as creating a vacuum to stop sonic-based weapons or transmutating the air into nitric oxide to anaesthize building occupants).
* WellIntentionedExtremist: T&I don't particularly want to hurt Ed, but they want his information and techniques, for the good of Konoha, at any cost.
* WorldOfSnark
* YouCanTalk: Ed's first encounter with Nin AnimalCompanions ends with him moving back in surprise, tripping over a dog, and pass out on the floor of a vet clinic.
