Summary
Frisk, a child who previously gave up on living due to having a hard time on the surface, falls into the Ruins. After spending time in Toriel's care, they find the strength to go on. To them, this means they need to leave the Ruins. After facing their first death during a confrontation with Toriel, they address the elephant in the room (or rather, the extra human in their brain): Chara. Chara has no memories of their life and no motivations in particular, but as they get to know the other human kid that they're stuck with, they can't help but get attached. Frisk reminds them of themself, somehow, as if they were two sides of the same coin.
Together, they traverse The Underground in their now shared body, meeting foes, friends, and foes turned friends along the way. Despite having previously considered themselves good as dead (or actually dead in Chara's case,) they find their hearts crying out that they want to live, no matter what that ends up meaning to them.

Metamorphosis - Alternate Title: Equally Unfair Circumstances by Rando_internet_Guy

Summary
Frisk has been through a lot. The Underground was quite the journey, with a race of monsters that wanted them dead and an unknown malicious entity that had possessed them, and after a run they'd rather forget the entity is gone. Now, they and Chara are busy trying to help monsters integrate with humanity.
However, there is a reason Humanity doesn't know about magic, and that reason is keen to keep magic away from Humanity, with the belief of the ends justifying the means.
Opposing secret organizations, overseers with plans of their own, finding themselves in a situation where a single kid overturns the status quo that has reigned for decades. A kid that simply breaks all previously known rules.
However, every will can be broken, no matter how strong. So, the Willbreakers lock and load and are sent to handle the threat, with the goal of eliminating the anomaly. And so far, they have done a good job of keeping Frisk firmly in step one.
However, in a distant universe, a human has made a promise to an entity that wishes to compensate for its actions, and through the creation of a Dark Fountain they are now here.
This wasn't how anything was planned, but it will surely be very, very interesting.

Between set schedules, filming, script readings, proof-editing, dress rehearsals, and his own hang-ups about those star-studded events, Tenna rarely makes a public appearance. This time, though, there was no saying 'no' to the offer of a lifetime: an extravagant, exclusive invitation to an all-expenses-paid gathering of high-profile award winners.
Mettaton and Tenna find themselves in the same limousine, where their first meeting takes a sharp left turn as they find themselves caught dead in the middle of an assassination attempt.
Real drama! Real bloodshed! Real Pippins! Real... Feelings?! Scrap that last part.

Summary
After the events of the true pacifist route in Undertale Red & Yellow (with Frisk choosing to stay with Toriel):
Monsterkind has been living peacefully on the surface among humans ever since a young child, Frisk, saved them from their long captivity in the underground.
All is well for Frisk and their friends. All except Clover, a young boy who was recently brought back to life by Asriel Dreemurr as gift for his selfless sacrifice in the underground. While he appreciates his second chance at life, he has never gotten over a friend he wishes he had never had to say goodbye to. Chara Dreemurr, the first human to fall into the underground, and one of two ghosts, alongside Clover, who guided Frisk through their journey, has not forgotten about her friend either. Unlike Clover, Chara was not given a second chance at life, and continues to watch over Frisk on the surface. While she enjoys Frisk’s company, Clover has always been at the forefront of her mind. Unknowingly to Clover, there is one way for Chara to return to the living realm. However, Chara has been hesitant to act on this.
After all, such an act would require a permanent marriage of souls.
