Harry Potter and the Alien Reality
by Maestro Hazard is a crossover of Harry Potter and Stargate SG-1, starting towards the end of Harry Potter and the Goblet of Fire and mid-way through the first season of SG-1. After Voldemort captures Harry after his resurrection, he reveals the truth of the prophecy and decides to get around it by banishing Harry to another reality, reasoning that this way the prophecy can never be fulfilled as neither of them are ‘available’ to kill the other, Voldemort reasoning that this makes him basically immortal. Having been sent to a world with no magic whatsoever, Harry is fortunate enough to appear in the middle of Stargate Command, prompting him to join forces with the SGC to find a way back to his world in return for giving them the opportunity to study his magic.
Harry Potter and the Alien Reality contains examples of:
- Adaptational Early Appearance: Elizabeth Weir appears during the meeting to determine the continued existence of the SGC after its first year in operation, and is subsequently appointed head of the SGC’s diplomatic branch.
- Alternate Universe Reed Richards Is Awesome: Even in the non-magical reality, James and Lily Potter were badasses as they were spies for MI6, with the alternate Sirius being so skilled that by the time of Harry’s arrival, he has risen to a senior position in the organisation, and is later appointed to serve as the British Government’s representative in Stargate Command, in a position of authority just under General Hammond but equal to Jack O’Neill.
- Child Soldier: Harry is basically one, but this is justified as the SGC recognise that he has unique skills and an unconventional background and is willing to help them against the Goa’uld.
- Convenient Terminal Illness: As well as Jacob’s cancer, Jolinar’s new host is dying of a terminal disease that prompts the decision to be blended.
- Dead Alternate Counterpart: While researching Harry, the SGC soon establish that Harry's counterpart in this reality was killed along with his parents in a car crash with the 'local' Tom Riddle, allowing them to create the necessary paperwork for Harry to essentially take his counterpart’s place.
- Dies Differently in Adaptation: Rather than being frozen and shattered in the third season, Hathor is killed by an Avada Kedavra from Harry during her first appearance on Earth.
- Death by Adaptation: In a roundabout way; the Remus Lupin and Peter Pettigrew of the ‘Stargate’ universe have died years ago, Peter dying in a car accident before the alternate Marauders left school and Remus dying of complications in surgery two years ago.
- Doppelgänger Gets Same Sentiment: When MI6 investigates the SGC's interest in the Potters, it leads to Harry being introduced to the local version of Sirius, who now goes by his codename 'Orion'. Despite Orion’s own godson having died as an infant, Orion and Harry soon become fond of each other, and the SGC's willingness to help Harry leads to the British Government volunteering to help provide the SGC with resources and financial support in the war against the Goa'uld.
- Drama-Preserving Handicap: Harry can’t use Reparo or equivalent charms to fix alien technology such as a damaged DHD because he needs to have a clear idea of how the device should be normally to fix it, and the DHD is too complicated for him to understand.
- I Know You Know I Know: Suggested on a couple of occasions, such as when Harry stuns a stubborn government official and says the man will wake up naturally in a couple of hours; he could wake the man up earlier with a spell, but so long as nobody asks if that’s possible, Harry won’t lie.
- If I Wanted You Dead...: A non-fatal example of this; Harry demonstrates the Imperius Curse on Omoc to make it clear to the Tollan that the SGC genuinely want to help even when he could have forced them to share their technology with Earth.
- Magic A Is Magic A: Occlumency is able to help Harry resist other forms of mental manipulation as opposed to just legilimency, ranging from resisting Hathor’s nishta to making it hard for the Keeper to read his mind. Harry is even able to teach this skill to the rest of SG-1, granting Sam a degree of control when Jolinar takes her as a host.
- One-Steve Limit: Invoked; when Harry meets Sirius Black's counterpart, the alternate Sirius reveals that he has gone by his codename, Orion, since the Potters of this family were killed, helping Harry distinguish between the two versions of Sirius.
- Reasonable Authority Figure: Sir John Kerr, the British Ambassador to America, offers a very reasonable deal to the SGC when he and Orion come over to meet Harry; in return for a sizeable British presence on the base (including a British officer to act as General Hammond’s second-in-command, albeit sharing that authority with Jack O’Neill) and access to any technology developed by the program, the British government will cover 30% of the SGC’s expanded operating budget.
- Secret Test of Character: Never explicitly stated, but thanks to Harry making it clear that he won’t use magic to force them to do anything when he could easily do so, the Nox and the Tollan are more willing to share purely defensive technology with the SGC, such as Nox shields and the Tollans' phase-shifting technology.
- Shout-Out: The first device created for the SGC by essentially reverse-engineering Harry’s magic is a silver tube that can unlock any door, which Orion explicitly compares to the sonic screwdriver; Harry’s lack of recognition prompts Orion to observe that he’ll have to ‘introduce’ Harry to Doctor Who when he gets back from the next mission.
- Shut Up, Hannibal!: At one point Harry uses a Silencing Charm on Maybourne just so that he can be sure of being allowed to say his piece during an official hearing when discussing the situation with the Tollan and the Nox.
- Spanner in the Works: Harry represents an unexpected factor to most villains faced by the SGC as none of them are used to facing magic, although SG-1 take care to ensure that Harry doesn’t do anything to expose his magic to the Goa’uld even if the NID are aware of his abilities.
- Spared by the Adaptation: Thor’s Hammer isn’t destroyed as Harry is able to apparate himself and Teal’c past it, and Jolinar’s life is saved because Harry was able to read her mind and confirm that she could be trusted, allowing them to set a trap for her would-be killer before the Tok’ra arrived with a new host.
- Unmanly Secret: A relatively minor example; when demonstrating the Imperius Curse on Maybourne (with the man’s permission), Harry asks Maybourne to tell him an embarrassing secret, and Maybourne reveals that he watches Power Rangers.
- Wrong Genre Savvy: Invoked; when SG-1 infiltrate Apophis's ship, Teal'c advises Harry to only use stunners, as the energy the spell generates is similar to a Goa'uld weapon.
- Your Magic's No Good Here: Harry can still use his own magic in the Stargate universe to cast spells, but there is no residual magic for him to use to reverse the ritual that sent him to this world so that he can return to his own.
