I'd almost like to see Frisk as a villain. Like, centuries into Frisk's life, they've done everything there is to do, like Flowey x100 000 000 and is now finishing exploring all the possible ways to help humanity, destroy it, have it destory itself, make it suffer. Everything. Though Frisk has lived for hundreds of years counting resets, it might just be a few years in real time. You might play as a human who has a red soul, or hell, maybe a new traid like Selflessness or something like that. Frisk starts out as your friend, and helps you through your adventure. But you slowly begin to learn of all the resets and once you start to know too much, Frisk turns on you for the 2nd half of the game.

Another possible idea could be something along the lines of Glitchtale's 'Hate'. It could take place after the True Pacifist ending and humans with very powerful souls are being consumed by and energy called 'Hatred' (which turns your soul black) and you might play as Frisk attempting to battle the ever-growing power of Hatred.

Though honestly I think the best way to do a sequel to Undertale would be the most popular: A prequel. Seing younger versions of the characters and putting everything in a different light. Expanding on the meta properties of the original game and taking it to a whole new level. Maybe the game starts off as you as a human venturing through the Underground with Flowey by your side (like Undertale Yellow), but you then get wrapped up in the life of Sans and Gaster and after your first run time begins to have a major affect, there could even be a time travel element to it.

Another good way to do a prequel is have the game be based around Flowey, seeing them start out scared and confused and then grow to become whatever you want them to become. A hero, a villain, a spectator, anything. But give it a unique and interesting story that isn't entirely related to Undertale's plot.

I don't think their should be an official sequel at all, I think the game has run its course. But I think fan games based around those 4 ideas (seperately, of course) would be great.
