Undyne

En guarde! You won't get away from me this time! You've escaped from me for the LAST time! STOP RUNNING AWAY!!! COME BACK HERE, YOU LITTLE PUNK!! Ngahhh! Bring it on! C'mon! Fuhuhu! Ngahh!! Urahhh!! You're strong... But not strong enough! You're a pain in the neck, huh?

If you got past ME, you can do ANYTHING! So don't worry! We're with you all the way!

[Monster Kid] Undyne... You're... You're hurt... Hurt? It's nothing. Next time, listen when I tell you to leave, okay? [Monster Kid] Undyne... I... I'll take care of this! Get out of here! ... heh... "It's nothing"... No... s-somehow, with just one hit... I'm already... Already... D... damn it.... Papyrus... Alphys... ASGORE... Just like that, I... I've failed you. ... No... My body... It feels like it's splitting apart. Like any instant... I'll scatter into a million pieces. But... Deep, deep in my soul. There's a burning feeling I can't describe. A burning feeling that WON'T let me die. This isn't just about monsters anymore, is it? If you get past me, you'll... You'll destroy them all, won't you? Monsters... Humans... Everyone... Everyone's hopes. Everyone's dreams. Vanquished in an instant. But I WON'T let you do that. Right now, everyone in the world... I can feel their hearts beating as one. And we all have ONE goal. To defeat YOU. Human. No, WHATEVER you are. For the sake of the whole world... I, UNDYNE, will strike you down! You're gonna have to try a little harder than THAT.
