Just out of curiousity honestly!!

Quick explanations for each below~

Flawed Pacifist/Family Ending

Failed Pacifist ending where you failed to date Undyne or Alphys, or dated Alphys and skipped the True Lab segment. None or few monsters killed (for most variants)

Toriel returns to the throne and people accept her policy for peace with humans

If you fail to date Undyne, she blames you for Asgore's death but otherwise seems fine

Undyne is pumped to speak with Frisk if she is befriended, just sad about Asgore

Betrayed Undyne endings here are possible if Papyrus is alive, you befriend Undyne, and killed any monster afterwards.

Alphys speaks with Frisk if befriended and reassures them of the progress to leave the underground

Papyrus joins the Royal Guard (after disbanding) and only waters flowers but is happy. Sans seems relatively happy too

Killing MTT will cause Alphys to disappear and Undyne to be distraught, not even wanting vengeance. Papyrus tries to be encouraging

Exiled Queen Toriel

Many branches!!! Toriel attempts to rule but either resigns peacefully or is banished back to the ruins, either by Undyne or the monsters themselves.

Overall, monsters are unhappy with Toriel's policy due to the killings by us, even more so if Undyne was killed

Sans and Papyrus (if he's alive) will follow her to the ruins and keep her company

Sans will drop the facade with you if you also killed Papyrus, saying your not welcome back in the underground

Killing MTT will cause Alphys's "disappearance" and Undyne to be distraught, sometimes wanting vengeance

Empress Undyne

Sometimes a variant of the Exiled Queen endings where if Papyrus or many monsters are dead (Alphys disappears), Undyne herself leads a revolt against Toriel and becomes Empress of the Underground

She's a tougher leader who takes the idea of war on humans more seriously than Asgore

She also becomes Empress if Toriel is killed as long as 10+ monsters are killed as well

If Papyrus is dead, Sans will drop the facade and reveal he knows you killed Toriel

If Papyrus is alive, he's given a falsely important role by Undyne. Sans just comments on Tori's silence

King Mettaton

Capitalist dystopia led by Mettaton after Toriel and Undyne are both killed.

Sans and Papyrus become MTT's agents

Sans doesn't comment on Papyrus's death in this ending and is still MTT's agent

MTT comments on his regrets with Alphys, and says she's disappeared

People who don't like MTT's show tend to "disappear" (😧)

King Papyrus

All possible leaders are gone; Papyrus becomes ruler by process of elimination

Papyrus tries to be as encouraging as he can, despite losing so many important people. His best encouragement isn't enough

Sans takes over the paperwork, Paps is proud

Sans told him that everyone else went on vacation, though it's implied Paps already knows the truth and just plays along

The most neutral human policy: can't judge them all to be good or bad, it's a case-by-case

Dog Ending (Leaderless variant)

Silly ending; All bosses (Toriel, Paps, Undyne, MTT) killed but NO ONE ELSE

Sans comments how a white dog became president of the underground and sleeps on the throne all day

this seems like the best ending for everyone -Sans

Leaderless

All bosses are killed, as well as some monsters. Small variant if there's 20+ monster kills

Everyone is distraught since no one can step up to become a leader. All hope is gone

Sans darkly jokes that this is what happens when people like him take it easy

If 20+ monsters are killed as well, Sans comments on the emptiness and also for you to "go to hell"

Queen Alphys

Aborted Genocide ending after Undyne the Undying

Alphys is the one who asks for the call, Sans barely comments

Alphys evacuates everyone, making monsters look to her for leadership after

Sans seems to be supporting her for now

Alphys reveals her secrets to the public and it seems to be relieving to her, though now she has regrets with us, saying how she should've killed us when she had the chance (RAW FR)

Dirty Hacker Ending

Technically a secret "impossible" ending. You have to hack the game save file in order to get this ending

Sans comments on how strange this is and to contact the creator, maybe for a "new ending"

Sans breaks the fourth wall by calling out the player as "just a dirty hacker"
