Fanfic: Harry Potter and The Invincible TechnoMage
Harry Potter and The Invincible TechnoMage is a Harry Potter/Iron Man Crossover Fanfic written by Clell65619. The plot involves a 5-year-old Harry and the Dursleys visiting Stark Enterprises. Dudley accidentally causes a chain reaction that kills the Dursleys but Harry is saved by accidental magic. Tony Stark at first shocked that someone survived the explosion eventually decides to adopt Harry giving him the name he is known by throughout the fic: Harry Stark.At its heart the story is a crossover between Harry Potter and the Marvel Universe with increasing cameos from Marvel outside of Iron Man. Eventually Harry is found by Dumbledore and invited to Hogwarts on his eleventh birthday. Harry is reluctant, but having been told of the dire consequences should he not go eventually convinces him that he is needed at Hogwarts.
Brick Joke: When Sirius is waiting to meet Tony he has a slinky and a yo-yo to keep himself occupied. Later on Snape mentions that these two toys were fads during his school days and that he tried to set a school record for most steps descended by a slinky.
Curbstomp Battle: The Marvel Universe outclasses the Potter Verse in almost every way in this story. Not only can a Muggle like Iron Man breach the security wards of Hogwarts (finding it with the help of Captain Britain and Meggan, two magical Marvel Universe heroes), Harry was trained by Doctor Strange of all people, effectively eliminating his need for a magical education. Also, magical culture is shown to be stagnant and backwards, filled with ridiculous amounts of Fantastic Racism and corrupt to high heaven. The two reasons the Potterverse shows up at all are because Harry can't avoid the prophecy, and because (per Word of God) even though there exist god-like beings (as well as actual gods) in the Marvel Universe, many of them focus more on the Galactuses and the Doctor Dooms, while leaving lesser heroes to take care of lesser villains, which Voldemort counts as in this world.
Evil Cannot Comprehend Good: Tracey Davis' grandfather orders her to seduce Harry in order to ensure the Potter fortune ends up in the Davis' family's hands. Any actions Tracey takes as just being Harry's friend are mostly taken as in-roads towards fulfilling those orders, without taking into account that, maybe, she cares not for the orders.
Kidfic: The premise of the story is Tony Stark raising Harry Potter.
MagiTech: After Reed Richards from the Fantastic Four discovers how Potter Verse magic works, Tony uses this knowledge to design Iron Man armours that can work within Hogwarts' anti-technology field (such as the exo-skeleton he gives Harry). Later on, Muggle electronics such as cell phones and CD players are introduced to Hogwarts, causing much frustration for Dumbledore. Finally, Harry's senior project is to design a magical computer that partially involves replacing circuits with ancient runes.
Dumbledore doesn't like that the electronics can now run on Hogwarts' magic, which is draining the wards of the school. Chandrahas Patil, Parvati and Padma's father, had built a tower outside of Hogsmeade on property he owned, and both he and Tony are partners in a Magical Consumer Electronics Shop in Diagon Alley. Filius and Snape tell Dumbledore once the novelty wears off, they'll be back to normal.
Mugging the Monster: A hick wizard that had been living in NYC by robbing rich teens makes the mistake of taking Franklin hostage since he deemed Neville and Harry, both wizards, to be a bigger threat. Though Harry by himself can decimate half of the city before he is stopped, Frankin, being an omega class mutant, can destroy all the world if he loses control.
Muggles Do It Better: Reed Richards utterly defies his own trope (while playing another one dead straight) and makes Harry-Potter magic functional around technology, and Tony manages to make a cheap energy source out of it.
Another one given as a reaction to Sirius, a group of terrorists show up at a charity dinner to do general terrorist/robber things. Sirius, trying to play himself off as a costumed hero, decides to call himself "The Wizard," inadvertently taking the name of a fairly notorious Marvel Supervillain. The reaction subsides when the terrorists/robbers realize that it isn't the same Wizard that they were thinking of, but comes back when Sirius beats them all.
Once Snape realizes Master Alchemist Esteban Corazón de Ablo was the one who belittled him in front of the staff, he puts one on (as he had de Albo's text which included brews he didn't evey try to make himself). Dumbledore gets one as he finds de Albo's found Neville's the student that inspired the Alchemist to teach again ("The boy has potential, a sense of wonder, and a willingness to learn I've rarely encountered over the years.")—and is considering NEVILLE for an apprenticeship (which Dumbledore himself never got from de Albo).
The Prankster: The Weasley Twins are as usual and Neville, after he gets alchemy training from Master Alchemist Esteban Corazón de Ablo, letting him brew a potion will let him animate anything it touches for half an hour to his commands. This is a big role in him helping his classmates get the better of Kree who kidnap them: make enlarged duplicates of Spider-Man action figures that respond to Neville.
Screw You, Elves!: The tone of this story is very much on the side of Marvel and very harsh towards Wizarding Culture. Not individual wizards or witches, mind you, but to the culture itself, which is portrayed as ridiculously racist and stagnant.
Shout-Out: There's a brief reference to Gotham City from the DC Universe put in as an in-joke. Also, Harry is reading a Garfield book while on trial by the Ministry as they attempt to declare Tony Stark's adoption illegal.
While he has Neville in the States, Harry and Franklin bring him to an arcade, where he turns out to be a prodigy at playing Terminator.
Straw Loser: Severus, Dumbledore, Fudge... pretty much the fic is a continual "You suck" to the Magical World and the Potterverse.
Take That: In addition to the discussion of "Who would play the cast of an Iron Man Movie" mentioned above, Tony scoffs at the idea that Jarvis would be played by an A.I and not a human being like the real Jarvis (who in the comics is the Battle Butler of The Avengers).
