A/N: Just more 'what if' scenarios that I pondered while trying to explore the first one that I had thought of. They may appear fairly similar, but they have the potential of being vastly different. I find the idea of a 'sparkling' Harry to be both adorable and hilarious. I hope that I gave a reasonable explanation of how Harry could wind up in the Transformers universe. If someone does want to use this idea, don't feel compelled to use everything that I've written. I'm putting this up to see what will happen. Just please give me credit for using this idea and let me know, since I'd love to read anything written that was inspired by this.
What if the Cube had created the Harry Potter world, before it disappeared in a rift to another dimension where it created Cybertron? What if the 'magic' of the HP world was just the Cube's energy manipulated differently than on Cybertron? Their 'magic core' was really just a human's ability to use the energy of a 'spark'. The Veil in the DoM leads to the Earth of the Cybertron dimension. Time passes much more quickly in this dimension than it does in the HP one. When Sirius falls through the Veil, he winds up accompanying Captain Witwicky on his adventure of the Artic Circle. When he dies, he leaves a literal fortune to the person that would be able to answer three questions, as well as find a key that he hid somewhere in the world, with only a riddle as a clue. A month after Sirius falls through the Veil, Harry ends up going through as well. His attempt to discover his animigus form leads to a rather spectacular explosion after Voldemort shows up. The Dark Lord dies(optional). Fudge declares Harry going Dark and has him executed. Dumbledore isn't able to prevent him from being sent through the Veil, either because Fudge won't listen or he figures that killing Harry would make him able to kill the Dark Lord himself since it was one less horroucux to deal with. Harry gets sent through the Veil. Wakes up in a hospital and sees a special on 'Lord Black's unclaimed fortune'. Knowing that he needs money, he quickly escapes from the hospital and makes his way to the lawyer's office indicated in the program he had seen. Answering the questions easily, he then has to solve the 'riddle' which was actually the exact location of where the key could be found without actually out right giving names. 'You can find the key to my fortune in the den of the lions where the motto is to never tickle a sleeping dragon. Then again, some lions are bolder than others and wouldn't hesitate to brave the flames.' Find Hogwarts (I think that the school motto is Latin for 'never tickle a sleeping dragon'), or the ruins that would be Hogwarts, and look in the fireplace of what would be the Gryffindor common room. Easy enough to do. Finding the key, which was the only copy, since the bank had destroyed theirs upon Sirius' death, Harry claims the fortune and establishes a new identity. As an emancipated minor, he goes to the States and ends up in Sam's school.
Before the Cube is destroyed: Harry buys the glasses, and thus ends up getting dragged into the chaos of the Autobot war with Sam and Mikaela(optional). Harry saves Jazz, keeping his Spark from dying completely by using his own Spark/'magic' to keep Jazz alive until Ratchet can stabilize him. Harry drops out of high school to help Autobots set up a new home, feels guilty about destroying the cube. His role in that can be as little as helping Sam or destroying the Cube himself. His direct contact with the Cube before it was destroyed allows him to shift into his Animigus form, which is a sparkling. Despite being nearly fully grown as a human, he is the equivalent of an infant or toddler as a Cybertronian/Autobot. He doesn't actually shift forms until a near death experience forces the change. Can incorparate something from RotF, if you've seen it. Although it might work better if it wasn't. Since he didn't willing change, he's stuck in that form. Autobots become insanely protective, especially when they realize that the sparkling is Harry. When other Autobots arrive, they discover chaos and the scary sight of a protective parental Ironhide. Sparkling Harry is able to transfer his Spark energy into others, which causes a few blown gaskets when Sparkling Harry does it to stabilize an injured newly arrived Autobot. Sparkling Harry is also able to sense each Autobot's unique Spark 'signature', same can be said for the Sparks of Decepticons. Ability to sense Energon(optional). Because the Cube was destroyed, no more Sparklings, but Ratchet soon discovers that the program that allows them to adapt to survive in foreign environments takes it one step further by giving them the ability to get 'pregnant'. He comes to this conclusion after Sparkling Harry asks rather 'innocently' if Autobots needed to use protection when they had what was the equivalent to sex. His demand for proof that Autobots can't possible get 'pregnant' leads to Ratchet discovering that their survival programming actually made it possible. A fail safe if the Cube was ever destroyed. When the Autobot couples are told to remain celibate, until a form of 'protection' can be found, hilarity ensues. Reasoning behind this was that they didn't want to bring any new sparklings into the world until they had a reliable source of Energon, since Sparklings were particularly dependent on it for the first so many years/centuries of their lives. The hilarity winds down when Sparkling Harry asks if the survivor program would even let them get pregnant if Sparklings couldn't survive without Energon. Ratchet once again examines it, and comes to the conclusion that although they could now get 'pregnant' it wouldn't happen if they didn't have a reliable source of Energon. As much as they could adapt, Energon was too essential for their survival to be replaced. As adults, they could last several centuries on the stores that they had and the fuels of Earth. Sparklings however, feed almost solely on Energon, which is why Sparkling Harry is watched over so carefully. The small amount of Energon they had, which wasn't alcoholic to a Sparkling was quickly disappearing. Sparkling Harry needs to change back into his regular self before supplies run out. Time can be bought with the arrival of more Autobots, or Sparkling Harry finding an alternate 'food' source that will sustain him, at least temporarily. Problems with Decepticons, and Megatron coming back, optional.
After the Cube is destroyed: Harry senses Bumblebee's spark, and tries to figure out what exactly he is feeling. He is about to decide to ignore it when he senses another spark on his way home. When he goes to investigate, he finds a badly injured Decepticon, preferably Barricade. It's the weekend, so he spends it fixing what he can after having the vehicle towed to his home. As he works on Barricade, he notices that the spark is fading. Curiousity getting the better of him, he uses his 'magic' to stabalize the spark. The extra energy he supplies helps Barricade to repair himself in what he can. By the time the weekend ends, Harry has repaired everything he can, and replaced what he could do safely. Barricade wakes up while he is at school and tries to figure out why the hell he isn't off-lined. When Harry returns, the Decepticon tries to intimidate him, but fails miserably. Giant alien robots, although strange, didn't scare him all that much. Ending up in a new world, with a fortune left to him by his godfather, made him rather hard to shock. Voldemort, Snape, and the handful of creatures he came across also made it hard to scare him. Giant alien robots seemed friendly compared to giant man eating spiders, or giant snakes that could kill with a single look. Definitely friendlier than soul sucking Dementors. So, a talking car threatening death, although a bit surprising, doesn't really scare him. Barricade is surprised when Harry orders him to stop with the death threats and tell him if there was anything else he could do to help. Fixes the Decepticon a bit more, but not enough for him to shift out of alt mode. Something happens which forces Harry to shift into his Animigus form in an attempt to protect himself, fire, collapsing building, falling off a cliff, something or other. Barricade finds the injured Sparkling Harry, sees him change(optional), and manages to get him into his backseat. Since he can't change out of his alt mode, and knows nothing on how to care for an injured Sparkling even if he could, he goes looking for the only mechs that can help. Finding Bumblebee, he follows him to the Autobot base. Ironhide threatens to blow him up until Barricade demands that he at least get the injured Sparkling to Ratchet before he does so. Sparkling Harry decides to make his presence known by demanding that Papa Ironhide be nice to Daddy Barricade. At this point, all the Autobots on the base are present to witness injured Sparkling Harry scolding his Papa and Daddy for fighting. He screams bloody murder when Ratchet tries to examine him, and doesn't stop until he's seated on Barricade's hood and clutching one of Ironhide's fingers. Things go smoothly from there as Ratchet repairs his injured leg/arm/chest/something. Then Ratchet turns his attention onto Barricade and has to contend with a stubborn patient, which leads to a hysterical Sparkling thinking that his Daddy was going to die, and that his Papa had to save his Daddy. Sparkling Harry doesn't calm down until after Barricade is in his mech form and he can latch onto one of his fingers, which he then falls asleep refusing to budge. Barricade then goes into the explanation of how the Sparkling was injured, how he was injured, and how it had been Harry that had managed to keep him from off-lining. When discussion turns to what should be done with Barricade, Ratchet quiets all arguments by stating that he'll be staying with Ironhide, unless they wanted the Sparkling to hate them. Thus begins Barricade's and Ironhide's adventure in parenthood. Before Sparkling Harry changes back, he needs to come up with nicknames for everyone, cause mass panic by disappearing for several hours, get into someone's stash of 'alcoholic' Energon, declare that he'll marry someone when he grows up, and gives someone a new paint job. When he turns back into a human, Harry brings Jazz back to life by using his bond with his sparkmate, since even though he's dead, he still has a connection to the living world through his sparkmate, a connection that won't disappear until after his body is destroyed in his funeral. Jazz can't get back on his own without something that can channel his spark through his connection to his sparkmate and back into his body. The All Spark has been used to do this before it was lost, only a handful of times, since most don't survive the loss of their sparkmate. Harry's ability to sense sparks, as well as channel energy leads to him feeling Jazz's desire to return to his body. So when he touches Jazz's sparkmate in an effort to understand what he was being asked, he finds himself blasted away and slamming into Jazz's body. As soon as he touches Jazz, the connection he needed to return to his body is made and Harry finds himself forced back into being a Sparkling before his body was overwhelmed by the sudden influx and withdrawal of energy. Jazz wakes up with a hysterical Sparkling Harry on his chest demanding for his Papa and Daddy. Problems with Starscream and Decepticons optional. If there are problems, have Harry kidnapped, as a human or Sparkling, and cause insanity until he is 'rescued'.
After being sent through the Veil: Harry wakes up in his animigus form, which is a sparkling, in a world different from his, still on Earth, but not his Earth. Beyond disoriented, he unknowingly releases a distress signal from where he is stranded. He is found by Ironhide, Barricade, or an evil organization bent on world domination; he's found by someone. Isn't capable of actual speech, but rather clicks, chirps, and whirs; the Cybertronian equivalent of baby talk.
A/N: Thanks for reading. If you find something confusing, let me know and I'll try to explain my reasoning so that it makes sense. Again, feel free to use any idea, but please let me know because I would like to read it, and credit is nice as well. Again, thank you for taking the time to read this.
