as a child, you fell down a hole on a mountain named mt. Ebott, and you found yourself in the Underground. You met a lot of friends (Sans the Skeleton, Toriel Dreemurr, etc), but you also met A FOE.
As you were walking next to a waterfall, a menacing figure was standing atop of it. It was clad in armor, a spear in it's hands. It was none other then the leader of Asgore's Royal Guard, herself. THE ONE. THE ONLY. UNDYNE THE UNDYING.
She then jumped, landing perfectly in front of you.
Undyne the Undying:"7. We need 7 human souls to open the barrier and forever beat humanity for sealing us away in here. For YEARS, NO, MILLENIA."
Undyne said, her voice mighty.
Undyne then raised her spear.
Undyne the Undying:"NOW, BRING IT ON, HUMAN! FIGHT ME! SHALL I WIN, I WILL BRING YOUR SOUL TO KING ASGORE SO WE CAN OPEN THE BARRIER, GET OUT OF HERE, THEN GET REVENGE ON HUMANITY AS A WHOLE! SHOULD YOU WIN... WELL, YA WON'T! CUZ I'M THE UNDYING, HECK YEA!"
Undyne sounded rather cocky.
UNDYNE THE UNDYING

Heroine reformed by her own DETERMINATION to save Earth.
Undyne threw one of her spears to you so you can fight properly.
Undyne the Undying:"C'MON, HUMAN, LET'S SEE WHAT YOU'RE MADE OF, STRIKE ME! LET US BATTLE WITH HONOR!!! COME AT ME!!! OH BOY, THIS IS GONNA BE SO BADASS!!!"
Undyne proclaimed enthusiastically, thrilled to have a good fight and prove herself in battle. She's bouncing around on the spot, waiting for your move.
