* CrossoverPowerAcquisition: Tangentially, since Alchemy and Magic work along a common base. Apparently, Voldemort's horcruxes are a form of human transmutation, and the first step is likely blocking Truth's ability to interfere with his Gate. Given he wasn't the inventor of the Horcrux technique, Mustang suspects that whoever did it had working knowledge of the Gate and Truth.

* BrokenPedestal: A wordless version. Dumbledore admits Flamel confessed the exact method of creation of the Philosopher's Stone, and his tone alone tells Mustang Dumbledore never expected a close friend to have done something so utterly awful, especially considering the sheer number of souls needed to keep him and his wife alive for so long.

* FrameUp: One of the first things Mustang warns his Alchemy students is that under ''absolutely'' no circumstances are they ever to experiment with arrays on their own. Some time later, Hermione's bag falls, spilling out an incomplete array diagram. A politely furious Mustang instantly sends her to detention, along with Harry and Ron when they try to defend her. When they present themselves, Mustang stops them and immediately tells them ''he'' was the one who slipped the array into Hermione's bag, so he could have a private conversation with them about their plans to start their defense club without anyone else from the faculty listening. Unfortunately, the tactic is invalidated when Umbridge is promoted to Headmistress, since by then she would have forced herself into any detention involving Harry.* FridgeHorror: InUniverse, Mustang has to restrain himself from calculating how many souls it took to create enough Philosopher's Stone to keep Nicolas Flamel and Perenelle alive since the Middle Ages.

* TheDarkArts: What the Order of the Phoenix assumes at first after witnessing Mustang's alchemy. Moody even admits he's not sure whether to point his wand at the Death Eaters or at the man who just nearly incinerated the entire group by himself. In a similar vein, the Ministry asks him to hand over the information on the lethal array, but he flatly refuses, determined to keep Berthold Hawkeye’s array safe, knowing how really dangerous it is.

[[https://archiveofourown.org/works/6870892/chapters/15678928 Colours of the World]] is an ''Manga/FullmetalAlchemist'' and ''Literature/HarryPotter'' crossover fanfiction by [[https://archiveofourown.org/users/MaiKusakabe/pseuds/MaiKusakabe MaiKusakabe]]

What particularly makes this fanfic unique is that it's told almost entirely from Roy's point of view, and the author has done an exceptional job of keeping him in character.

--> '''Mustang:''' [[spoiler: I'm stopping you from continuing with your reign of terror, obviously.]]
-->'''Umbridge:''' [[spoiler: You won't get away with this! I'm the Minister's right hand!]]
-->'''Mustang:''' [[spoiler: Not for long. I hear there is a Department of Mysteries full of Death Eaters that's about to cost Fudge his position.]]

* WhatMeasureIsANonHuman: Mustang wonders exactly why Truth considers Tom Marvolo Riddle's life worth less than a normal life, and while he's initially relieved to have the non-lethal option available, soon he realizes it's a pipe dream at best.

* KungFuWizard: While not shown, it is implied that members of the DADA also learned some form of physical combat in their lessons besides defensive spells. [[spoiler:There is evidence for this when Hermione, Ron, Neville, Ginny, and Luna all are physically able to subdue the members of the Inquisitorial Squad that hold them captive. Without magic.]]

* ImagineSpot: To Mustang's regret, whenever he imagines Alphonse Elric, he imagines him as the suit of armor, since he never saw him in the flesh.

* CrouchingMoronHiddenBadass: Mustang has perfected the persona of a charming but largely useless academic to the point eve the entirety of the Order of the Phoenix is fooled. [[spoiler:When confronting the Death Eaters, Moody thought that at best, he'd manage the alchemical equivalent of an ''incendio''... only for Mustang to nearly cremate the entire group with Flame Alchemy far closer to controllable ''Fiendfyre'' and then go on to brutally repulse Voldemort. Speculation immediately changes to how it was possible such a skilled and powerful combatant hid as a teacher without anyone realizing what he really was.]]
