What happens if you kill Asgore in a pacifist run?

If the protagonist kills Asgore, he dies smiling. Before the protagonist can take his SOUL and pass through the barrier, Flowey shatters Asgore’s SOUL. He tells the protagonist they finally realized that this is a “kill-or-be-killed” world.

What happens if you mercy Asgore at the end?

Choose to spare him, and Flowey will make an appearance. At the end of his rant the game will crash (at least, on PC) and when you reload it your save file will be “corrupted” – don’t panic, it’s meant to happen!

Should I spare or kill Asgore?

Asgore forces the protagonist to fight him, and the protagonist cannot spare Asgore. If any of Asgore’s attacks hit the protagonist and they do not have enough HP to survive it, the attack drops their HP to 1 when it otherwise would have killed them.

How do you beat pacifist ending?

To get the Pacifist ending, you must not kill a single creature, plus spare (and date) every main character you come across. Doing so will see you access new content – so it’s well worth playing first. To get a true Genocide ending, you must kill a certain number of monsters, as well as their bosses before moving on.

Is Asgore the strongest monster?

Asgore is a powerful warrior. We saw him destroy battle options (the Mercy button) with his trident, he trained Undyne, who’s now head of the Royal Guard and quite possibly the greatest (or the second greatest) warrior in the Underground.

How much HP does Asgore have?

Keep Fighting It can be a long and tense fight, but players should stay determined and keep learning his attack patterns until the end. When his health is somewhere around 600 points, he will endure one last attack before falling to 1 HP.

Is Asgore a bad guy?

In my opnion, Asgore is NEITHER good or bad, he is Neutral. Just like Sans or Undyne for example, both just wants to protect their kind ( Even tho Sans lost his hope. ). Asgore is great.

Can you do a pacifist run first?

Yes, you need to complete a Neutral run before doing a Pacifist run. You won’t be able to go to the True Lab until that condition is met. If you’ve gone through your Neutral run without killing anything, then you are not required to start over from the very beginning.

You can’t kill mad dummy. He can’t die, except on a Genocide Run.

How do you get G in Undertale?

GOLD (abbreviated in-game as G) is the main currency used in the Underground. The protagonist gains GOLD primarily through winning encounters, whether that be through killing the monsters or sparing them.

What happens if you buy Muffets donut?

Using a Spider Donut or Spider Cider during Muffet’s fight ends it immediately. Buying a Spider Donut from the Spider Bake Sale at Hotland prevents the fight with Muffet entirely, except in the Genocide Route.
