Based on the two Undertale SmashBits Animations' shows, the crossover that nobody deserves, needs or wants.
After the death of LAD and saving of Asriel, it seemed that the adventures of Genderless Child and Human Child are over...unfortunately, Human Child's adventures (And Genderless Child's torment) are far from over, as they go in adventures that will change them...for better or worse...

Reset (Sans x Older!Frisk)
There are some things you just can't take back. No matter how many times you reset. After breaking free of Chara's grip, Frisk decides to do one final reset before defeating Sans or proceeding to the throne room. But some memories last longer than others, and broken trust isn't easy to repair. Female, aged-up Frisk. Starts out canon and then diverges. Eventual Sans x Frisk. Undertale was created by Toby Fox. I do not own Undertale, nor any of the characters. Some violent action scenes. Cover art is by amazing artists at http://www.zerochan.net/Undertale,Fanart and http://www.zerochan.net/Chara+(Undertale),FanartComplete

Undertale 2: Forgiven
Happy endings don't always come easy. Monsters in the Underground know that better than most. Especially when it comes to humans: their history, their fate, and how they Act. But if there's anything that monsters have to learn, it's that the actions of one human do not define the Mercy of another...

Undertale - Fighting To Stay [Frans] [Book 3]
So, monsters and humans have been living together on the surface for quite a few years now... That's an accomplishment! No resets, no new timeline. Just a future continuing forward like everyone could have possibly hoped for. However, not everything is hopeful. You can't expect to live a life where everything is sunshine and rainbows. Even with no longer having the threat of someone like Chara, things can still happen when you least expect them to. You can't always have your "Happy Ending".Complete
