Have this idea of a VigCup AU where they get to be a secret power couple.
Where Viggo survives Triple Cross by Hiccup's help, but who doesn't take the injured man back to the Edge, because for all that Hiccup trusts and loves his Riders, he genuinely doesn't know if they'll help him save Viggo's life.
Where, after a lot of time, multiple visits, and Hiccup secretly traveling back between the Edge and Viggo, they get closer, and talk stuff out, and spend time together.
The high point of this AU is Viggo becoming something of a rouge dragon rider (on the Skrill, of course). He only works and communicates anything related with Hiccup, refuses and evades anyone else, but becomes a formidable Dragon Rider, enough to gain a reputation. Enough of a reputation that the Riders try to establish communication with him (Maybe he feels like he doesn't deserve it, after everything he's done?), until Hiccup stops them by telling them that all those months he spent sneaking off was to "get to know and establish trust with the Rouge Dragon Rider".
I also just have the idea of Viggo, as a rouge rider, occasionally helping the Riders, but keeping a firm distance and silence with anyone but Hiccup. There's basically a lot of general drama (also outside the Riders) about the mysterious and powerful Rouge Dragon Rider.
(Does anyone question why his armor, gear, saddle, and so on, are similar quality and style to Hiccup's own? No, they don't realize for a long time.)
And I have this kinda comedic reveal scene in my head, which happens after the second movie (in which Viggo helped a damn lot during the main fight and was very involved with everything, but never showed his face), where the Riders (and everyone else?) finally start asking who the Rouge Rider is, and it kinda goes like this:
"Who is he, Hiccup?"
"Just, just an old... friend, yeah."
"I would hope after all this time that I've become more than just a 'friend', My Dear Hiccup."
And like, they weren't even planning whether to reveal or hide who Viggo now is (there was a lot of other stuff going on, with the second movie and all that), but the ones who know heard "my dear Hiccup" and kinda just go "VIGGO?!?!"
Anon may your bed always be the exact temperature you want it at, I love this idea SO MUCH!! Thank you for sharing; this is going right into my list of future fic ideas!!! Secret power couple vigcup my beloved
So many possibilities exist with this idea!! So many extra things could be worked into it!! Anon I love thissss im so happy you shared it!
The angst of Hiccup who trusts the other riders with his life, but doesn’t trust them with Viggo’s life/doesn’t trust them to trust him.
Rogue dragon rider Viggo who only works with Hiccup! They come up with so many ideas together that are honestly terrifying for any enemies they’re up against because you have two of the smartest people in the archipelago, one who used to make terrifyingly efficient weapons if only he had been given the chance to perfect them and one who knows the ins and outs of running an efficient business with questionable and horrifying business practices, and now they’re working together? The power couple of all time; enemies should save themselves the trouble and just surrender before the fighting even starts.
No one else knowing who the rogue dragon rider is until Viggo sticks around long enough to call Hiccup “my dear Hiccup” and everyone clocking it immediately because there’s only one person that’s ever called Hiccup that specific name and it’s their presumed dead former enemy
It would be such a funny reveal I love it so much omg I need to write this au!!!
