Besides the obvious (stronger monsters, faster attacks etc.)

Pacifist/Neutral:

- Mettaton's quiz, maze and bomb-defusing will kill you if you fail them

- Papyrus' challenge can't be skipped

Pacifist Exclusive:

- If you die to Asriel (non-hyperdeath mode) you start from the beginning of the fight.

- Gaster encounter in the True Lab

Neutral Exclusive:

- No rubberbanding on Omega Flowey / you can die during SOUL phases

- If aborting the Genocide run in Snowdin after killing Sans (see below), Papyrus will be much harder.

Genocide:

- Sans goes back on his promise and attacks you immediately after leaving the ruins. You can spare him and he won't dunk you, allowing you to abort the run. But if you continue the run, Papyrus will take Sans' place in the Judgement Hall. - Mettaton NEO puts up a fight if you've killed all Hotland/Core enemies
 * Undyne takes Papyrus' place
 * Alphys takes Undyne's place

- Asgore absorbes the six souls and challenges you

- New Home as accessible area between Mettaton NEO and Papyrus. More grinding, new level cap of 30

Oooh, I kinda like both these ideas. Though, I've thought about giving the soul to Asriel, but I reckon I'd break the meta-logic of the game. Still, cool. undyne's bedroomOh, you pervert~
