Feedback AU

"You ain't never gonna have a friend like me, Dipper... mostly because I AM you." (source)

Feedback AU is a sub-AU.

In the year 20-Snyventy-12, Time Baby sends a squad of his best soldiers, equipped with extremely powerful and dangerous relics and equipment blessed and endowed by various deities, including the Axolotl and the big guy upstairs himself, to capture Alcor out of apparent fear that the demon might one day challenge his rule of the world and take him out. Despite his immense level of power at the time, Alcor found his back against the wall, and in a desperate attempt to escape, the dream demon used his newest and most dangerous power, and attempted to create a feedback loop. Unfortunately, Alcor ends up in the canon universe of Gravity Falls in the form of a sixteen-year old teenage human, despite not losing an ounce of his raw demonic power. Once there, Alcor quickly befriends the Pines family and devises a plan to pose as Stanley Pines’ grandson that he didn’t know about, and takes part in the Pines’ hijinks and misadventures throughout the summer, as well as getting up to hijinks of his own before the twins' inevitable return for their second summer.

Notable Features of this AU are:

• Alcor the Dreambender is voiced by Troy Baker. See here for a demonstration of what Alcor sounds like in this sub-AU.
• Alcor’s cane sword is modeled after the cane swords from Assassin’s Creed: Syndicate, and has an ebony horned sheep head as a nod to Alcor’s flock from his home dimension, and a black and silver blade.
• Alcor refuses to tell his origins to his younger counterpart, Mabel Pines, Stanley Pines, Stanford Pines, or anyone for that matter, and it isn’t until Dipper and Ford use the Mind Reader during the events of The Last Mabelcorn that they learn the full story of the events of the Transcendence and that Alcor has, from their perspective, been living a fate worse than death, especially after he accidentally killed the Wendy Corduroy of his dimension in a fit of demonic rage and the Mabel from his dimension passed away.
• Due to his accidental transformation into an immortal teenage human (although he later discovers he can change his age at will, thus allowing him to grow old with his beloved), Alcor now believes himself free to engage in romantic and sexual relationships, and actually manages to have one with none other than Wendy Corduroy, which ultimately results in marriage and the birth of Alcor’s son and daughter, Anser and Wenda Pines. Needless to say, once Alcor starts courting Wendy, Dipper and Robbie are NOT happy, and even combine forces to sabotage the relationship.
• Thanks to Alcor’s meddling with their minds, after the events of Double Dipper, Preston and Priscilla Northwest loosen Pacifica’s leash, allowing the heiress to go out into town more freely, wear whatever outfit she chooses (unless it’s for a party) eat whatever she chooses (unless it’s for a party), and no longer force her to obey her bell, thus allowing the real, far nicer and compassionate Pacifica Northwest to shine through her stuck up, snobby, mean, valley girl stereotype to the point where most people don’t even recognize her, which in turn causes a romantic relationship to blossom between her and Dipper Pines. However, despite this, the Northwest patriarchs continue to be the stuck-up, arrogant, and pompous jerks who treat the townsfolk as though they’re something unpleasant on their shoes that they’ve always been. According to Alcor, this was intentional so that Archibald Corduroy aka the Lumberjack Ghost could “still have his fun” during Northwest Fest.
• Despite falling in love with her once again and finally achieving his adolescent dream of marrying and starting a family with her, Alcor is still haunted by the accident that led him to kill the Wendy Corduroy of his home dimension, which led to the creation of his fox familiar, Anser, whom his son is named after, and secretly fears that he could lose control again and kill his bride.
• Alcor has been shown to be very skilled on the violin, to the point where Dipper considers trading in his tuba for a violin, despite, in The Dreambender's own words, "having picked up the violin for shits and giggles, then, he liked it, then he got pretty good at it." Furthermore, Alcor has been noted to seem as though he is at peace while playing the violin.
• Alcor has an alarmingly nonchalant manner when talking about major events that do not directly affect him personally that he has either caused or been complicit in during his centuries-long life, regardless of how horrific or devastating they are to the rest of the world or even those persent, even casually refering to the California Incident that took place on April 29, 2038, which destroyed countless cities and killed hundreds of millions of people, Dipper and Mabel's own parents and their entire hometown of Piedmont being among the casualties, as "that one time I broke California."
