Random idea 💡(HP/MCU+)

[Lightcaster]

I will say that I'm not sure anyone has ever done something similar but I've had this idea rattling around for the past few days and have no idea how to turn it into a coherent story

General idea is that a guy reincarnates as Neville longbottom with a handful of wishes

Wish 1: fully customized on summon version of Atlantis with a full loadout of drones and puddle-jumpers from the Stargate universe, tweaking a few things such as making the Stargate work like a cybertronian ground bridge (Transformers Prime), and adding things like asteroid mining tech along with material processing, and manufacturing facilities which will allow the creation of tech related to the city including Stargates.

Wish 2+*: triad mate/soul bond between himself, dungeon core Symphony of Avalon and dungeon fairy/Winx club fairy Phyra Nicos(reincarnated from RWBY)
Effects: Telepathic/Empathic link = mental communication across any distance, Power multiplier = the closer the three are the stronger they are, Resurrection Chain = to permanently kill any of them all three must die within a 24 hour period otherwise they will resurrect with a penalty of no powers for 72 hours, Power/Skill Sharing = both Neville and Phyra get omniglot from Symphony and Neville gets wandless casting from Phyra
* I figure withall the effects listed it will require more than one wish

Character info:
Neville longbottom
Race wizard
Bonded to Phyra Nicos and Symphony of Avalon
Regains past life memories after waking up in infirmary after knock to the head falling off broom during first flying lesson

Symphony of Avalon
Race dungeon core
Integrated into cityship Atlantis
Bonded to Neville longbottom and Phyra Nicos
3 avatar choices Prime = 2 story armored knight, major = 1 to 4 beastkin, minor, 1 to 100 tinkerbell style fairies,
Powers bard style buffs and typical dungeon stuff
For purpose of resurrection chain considered dead if all avatars are destroyed

Phyra Nicos
Race Winx club fairy
Bonded to Neville longbottom and Symphony of Avalon
Powers elemental manipulation/Magic unable to use abstract magic
Aura semblance Spartans instinct, instinctive knowledge of how to use any item to its fullest potential items have 10% greater effect in her hands


Story follows HP cannon for the most part with exceptions like Neville inviting Symphony and Phyra to the rule ball during goblet of fire and Neville unloading a 9mil into Voldemorts face and scenes with Neville using omniglot to curse in as many languages as he can think of including klingon, Tolkien elvish, feringi, and more.

My man. Just write it! You can do it

Honestly this is me just throwing stuff at the wall and seeing what sticks I have zero ability when it comes to writing anything but I can storyboard all day long my brain is just weird that way.

The specific idea? No, not done before, because some of those properties are just too new for anything like this.
The general concept of someone finding themself in a fictional world with special abilities? Been around since at least 1943 (Silverlock), with one of the most successful (and similar to your premise - though quite different, similar - being the multi-author Herald Shea stories).

First, you need to decide on your focus - is this to be a collection of Easter Eggs for the reader with a story that just happens to thread through all of this, or is this a power fantasy attempt to "correct" a flaw in the original stories, or are you just after a grand mashup?
If a power fantasy... there are tons of fan fictions you can look to for examples. I've only read synopses so can't give examples.
If your goal is a story threading through all of these but something different, then, well, Herald Shea is a good model to follow, especially if you want something humorous (though the worlds he - and, more often, the other professors trying to figure out where he went - were the worlds of mythology and folklore more than fiction).
For a more serious story that took the "Easter Egg" route (and went with public domain fiction for the Easter Eggs - probably only half of it known to modern audiences but almost all of it to readers in the '40s and 2/3rds for readers when I was introduced to it, in the 80s), Silverlock (and, I presume, but only found out it existed a few months ago so have never read it, the sequel) would be a great template to follow. Though, to some degree, he followed the pattern laid out by Jonathan Swift in Gulliver's Travels (and even referenced some of the places Lemuel Gulliver visited), and H, Rider Haggard (who used his own stories but managed to bring Ayesha from the "She" franchise, Alan Quatermain from his Zulu stories and threads from his Aztec and one other stand alone that I'm blanking on all together in one story). A more modern take on this idea would be The League of Extraordinary Gentlemen.

Terrible. You could never turn this into a story without suffering through literal hell.

So niche, so specific, so hard to write. Balance is totally dead, so this wouldn't be a story with any kind of suspense because the MC would be without any equals.

This looks like a story with your favorite story and plot elements, so as the others said, you need to write it on your own if you ever want to bring this story to life!

Or... simply commission it.

Sorry, but even i, with my subpar skills, have my limits, it would 20 2-liter, bottles of wild cherry Pepsi to make a third of this doable...

What do you mean it's unbalanced
Neville is a wizard with a universal translator and wandless casting Phyra would essentially be a nerfed avatar with instinctive item mastery and Symphony is a dungeon core that would be more base/school than combatant.

The only things I think would be unbalanced are the proximity multiplier which was only really going to be a 1x multiplier for each member of the bond within 25 feet and it would only count 1 of Symphony's avatars and the resurrection chain which i was thinking would be an unknown/unintended part of the bond

fully customized on summon version of Atlantis with a full loadout of drones and puddle-jumpers from the Stargate universe,

Roflmao, you just got enough firepower, mobility, and defenses to blow up a fucking fleet with at least twenty to thirty motherships.

He can fucking obliterate anything in his way.

There is absolutely no balance in your story; your MC is invincible and has the firepower to obliterate anything, get anywhere in seconds, and has access to indestructible puddle jumpers with shields so powerful that they could probably fly straight through Hogwarts and create a long tunnel directly through the castle and the mountain beneath it.

And that's just ONE puddle jumper.

Atlantis has enough firepower to obliterate Hogwarts in a few seconds.

Anyway, I'd still read it and see your take on how the story develops. Why don't you give it a go?

That just means nerf the weapons and puddle-jumpers it would be a tradeoff for being able to customize the city. Besides the resurrection chain doesn't mean he can't die or that it won't hurt it just means that he respawns as long as Symphony or Phyra are still alive and remember their powers are locked/unavailable for 72 hours after respawn
Also "indestructible puddle jumpers"
Who said anything about them being indestructible

Their shields are so strong, NOTHING on Planet Earth, including HP spells, could break them.

You could literally enter the jumper and then smash into every enemy with your shields up, and could defeat anyone.

That doesn't account for the fact that marvel power scaling is BS. Besides if hulk wants through that shield he's gonna get through it and if he can so can any of half a dozen others not to mention the ones that just bypass the shield

Well, you already have a clear vision of the story, and it looks like you thought this through. Not like I agree, but hey, it's YOUR world, and I'd be really interested to see your vision of that world. Why don't you show us your vision of that world? All that's left is to put it in words. Why not just start with a couple of chapters? Maybe you can do it and enjoy writing.

First off... there is way too much going on here that requires what those of us in the TTRPG community would call "DM-Fiat" to work, narratively speaking. Better known as Deus-Ex-Machina. It screams power-fantasy / wish-fulfillment. If that's what you're going for, then by all means do it. From my perspective though, it's not going to be rewarding to write, or read, and will likely get lost in the sea of other power-fantasy / wish-fulfillment slop before you can gain any real traction. Unless of course, you can get lucky enough to be noticed.

To me though it looks like you're just trying to throw anything you can think of together into a massive cross-over fan-fiction, which honestly will just overcomplicate the narrative far more than they really need to be, risk breaking the world, and end in just another forgettable fan-fic at best.

I get that you're brainstorming, and that's all well and good, but what you're lacking here most of all, is clarity of vision, as far as I can see, so I've got only one fundamental question for you to ask yourself in order to try and help you address that. "What is the narrative that I want to tell?"

I can't sit here and tell you the answer. In truth, nobody can. That's a question only you can answer for yourself, and it should help you get a bit more clarity on your narrative goals.

As for advice, when writing cross-over stuff, it's generally a good idea to settle on your main focal point first (which you seem to have done, as the Harry-Potter universe) and then to select one or two other universes/fandoms that have a strong compatibility with your main focal point. As in, crossing them over won't cause either universe to implode or be broken irrevocably. Then typically create your own original characters within your primary focal point and have them be part of the bridge between the main universe and the cross-over ones.

For example, RWBY has a very high compatibility with the DCU, MU, MHA, and similar stories, but has a very low compatibility with Harry Potter (on account of the prevalence of Magic between both universes). Stargate and Harry Potter have a surprisingly high compatibility though given the prevalence of their Earth-Setting mirroring the real world, and how the general population of said world is (mostly) ignorant to the events, technology, and magic within both settings and stories, the only real clash is in the literary scaling of the universes, and the capabilities of the tech -vs- magic (as has already been addressed). The biggest clash here, honestly, is MU/DCU (Marvel Universe/DC Universe) and Stargate/Harry-Potter. The scaling and interplay between worlds, tone, and inherent narrative structure, just don't measure up in anywhere near similar scales.

Also, side-note, if you're talking about everyone's favorite redhead from RWBY, it's spelled Pyrrha Nikos.

I also have a few questions, which are more food-for-thought intended to help you get the gears in your head turning, than anything you need to actually answer here.

• Why Neville Longbottom? Why not your own original character(s)?
• What is a ROB?
• If you are set on using Neville, why are you breaking from his depicted characterization?
• How do the wishes actually make sense within the narrative you're trying to create?
• What's with the truck-kun/isekai? It really makes very little sense with how you presented it here, and I'm getting the impression the story could be written entirely without any isekai element.
• What purpose does the isekai stuff serve for your narrative?
• How is it happening?
• Why the crossovers?
• How are the crossovers actually happening in the narrative?
• What purpose do they serve for the narrative?

Next subject to tackle, the presented content and premises, since they're kind of all over the place here.
There is a fair amount of good ideas, sure, but a lack of any cohesion between them that could feasibly work for a narrative (as far as I can see).
Kudos for the creativity. That's gold and the mark of someone with real potential.
On their own, several of them are solid, the only one that really had me going "Huh? What's going on with this?" was the whole isekai thing. Honestly, it feels tacked on to try and appeal to Isekai fans, and little more than that, with the others that are just jumping around between all different fandoms, which as I mentioned, creates a number of problems and a discombobulated, jumbled, mess.

Towards that end, you should really be figuring out who your target audience is as well. Are you targeting Harry Potter fans? Stargate fans? RWBY Fans? Isekai fans? Who your target audience is should really help shape the elements that make the cut, while also shaping the narrative itself and its themes and foci.

Once you've got your target audience figured out, the next step is settling in on your narrative's overall premise. A singular, primary, focus or theme throughout the narrative from beginning to end, that drives the narrative forward. This will also help you shape your overall primary conflict, and from there, your antagonist(s) later.

Think about it. All of the world's most successful stories all have a singular primary premise. A single theme and conflict built around it, driving the story forward, and one that all of the other minor conflicts arise from and are built around. Specialize your story, your narrative, and your characters. Don't be like a Bard (TTRPG character class). The proverbial Jackass of all trades, and master of none (except for how some have typically mastered assholery).

Overall, I like the creativity, but as a story, this really doesn't work (based on what you've shared) because it is all over the place. You get bonus points for Stargate though, even if that really doesn't change much for the execution. If you are seriously committed to trying to write that, then go for it, and best of luck to you. I can only hope you'll consider the advice you've gotten here on the forum, and take it seriously. The rest is in your hands.

To start with your questions a ROB is a R.andom O.mnipotent B.eing, I chose Neville because I haven't seen anyone use him this way, I wanted Neville to be a reincarnator to explain his meta-knowledge hence truck-kun's fuckup that has the ROB three wishes (1 for city, 2 for wives, 3 for bond with effects), as for crossovers there is only HP and marvel with a pinch of RWBY to explain Pyrrha and Aura

With hogwarts starting in 2003 timeline starts 1992 MC is also tortured alongside his parents with that and medical memory intervention explaining why he grows up as cannon Neville. HP cannon proceeds as written with minor nudges from MC. Year 2 cannon divergence is pedo Lockhart MC would have been building a literary fraud case against him finds him about to rape one of the first year girls MC puts him down with a full mag to the face. Year 3 bogart is Thanos mocking his failure to stop him. Year 4 MC instead of Cedric. Year 5 refusal to attend umbitch's DADA class and every time she messes with one of the students he challenges her to a legal duel of satisfaction(meaning he can't kill or maim) purposefully only uses first year spells when umbitch tries to kill him he cuts her arms and legs off puts her in a box and ships her to the aurors office along with evidence of her crimes with a note that a copy had been sent to every magical newspaper in the world.
This is what I have for the HP arc
