"You're gonna have to try a little harder than *that*." Frisk heard as soon as he'd returned from the Timeless Void.

Knowing that, as soon as she finished saying this, she was going to throw a spear, Frisk summoned a barrier around himself.

As soon as he'd summoned it, Undyne summoned her spear and threw it hard at Frisk. Fortunately, because of his shield, the spear did nothing.

Undyne frowned a bit.

"So you're a magician, huh." she said, seemingly troubled by this. Undyne's smile then returned. "Don't worry, I've plenty more."

As she said this, spear after spear appeared around her and launched at Frisk. Seeing the flurry of spears approach, Frisk focused on keeping the shield strong. Blow after blow struck the shield as Frisk struggled to maintain it. After a few seconds, a few spears flew by, landing in the water around him.

Seeing this, Frisk smiled.

*She's already losing her focus.* he thought. *Seems that, in reality, I'M the more DETERMINED!*

As he thought this, a sharp pain suddenly cut in his leg. Before Frisk could figure out what was going on, he felt himself falling to the ground, into the water he was standing in.

After collapsing into the water, Frisk felt something brush against his face. Opening his soaked eyes to see what it was, he saw a leg floating in the water.

Before he could properly process the situation further, a hundred spears shot straight into him.

*Stay DETERMINED*

This pattern persisted over the next few attempts. Frisk would return to life, use his shield to hold his ground, then be struck from somewhere by spears that managed to bypass his defense. Limbs severed, deep lacerations, full impalement, all of it.

Eventually, Frisk started to figure out exactly what Undyne was doing. Every time he came back, she would gauge his defenses, find the holes in it, and exploit them. Each time it happened; Frisk died gruesomely.

*I can't just keep standing my ground...* Frisk thought this last time he died. *I need to run.*

As such, the following time he'd come back, Frisk immediately summoned his shield and began backpedaling through the knee-deep water.

"Where you do think *you're* going!?" Undyne yelled.

As she yelled this, she summoned another spear, aiming this one for the roof of the mouth of the cave Frisk was aiming for. Upon hitting the wall, massive boulders dislodged from it and came hurtling down, one of which falling right on top of Frisk, smashing him flat.

When the next attempt started, Frisk summoned his shield and backpedaled like he did before, though this time, when Undyne was summoning the spear, he expanded his shield to cover the cliff-face above. He then escaped through the crevice he'd come through before, back into the dark, grassy, maze-like area. Undyne, not wanting to lose this murderous Human, gave chase.

Upon entering the murky marsh, Frisk took cover inside a thick patch of the tall grass, making sure to hold as still as possible. Seconds later, Undyne appeared on the scene.

"Damn it, where'd they go?" she said.

*I have to get out of here.* Frisk thought to himself.

As he started moving to leave, the burning feeling of LOV re-entered his chest. His own voice then started echoing to him.

"Must kill." it said.

Frisk, because of the presence of Undyne, didn't dare to speak back to it. Instead, he simply continued to sit, hiding.

"Go. Use my power." the voice said again.

*Use my power?* Frisk thought. *What the hell does that mean!?*

"THERE YOU ARE!!!" Undyne suddenly shouted.

Frisk shifted the world back into focus, finding that Undyne had indeed discovered where he was hiding.

"TIME TO DIE, WHATEVER YOU ARE!!!"

Before Undyne could bring her spear down on Frisk, fire exploded out from Frisk's hands at her, knocking him backward, and lighting her front on fire.

"Kill her." Frisk heard the voice say one final time.

Frisk got to his feet. Focusing in on the surge of power coming from his chest, he forced fire into his hands.

As Frisk did this, Undyne caused air to blast away from her, dousing the flames that were engulfing her body. She then looked around, seeking where Frisk had gone.

"Over here, monster!" Frisk shouted.

Undyne looked to where the shout had come from. Frisk was standing there, his arms engulfed in flames that did not burn him.

Undyne brought up her spear arm, readying her spear to be thrown straight at Frisk, but before she could do anything, Frisk brought up his fiery arms and shot a beam of pure heat straight at Undyne's chest. This beam, as it traveled, also lit the grass around it on fire. The simple firing of this searing beam gave off so much heat that Frisk closed his eyes.

Soon after firing, the heat mostly subsided, only remaining as much as it did due to the fire now blazing across the brush. As the brunt of the heat had passed, Frisk reopened his eyes. He could see it all so clearly. The flaming grass, the smoked walls, and Undyne, who now featured a massive hole in her chest. Her eyes were wide, and her mouth agape.

"D-damn it..." she said slowly. "So even *that* power... It wasn't enough...?"

"No power is enough to stop my DETERMINATION." Frisk said.

"Heh..." Undyne said.

Frisk stepped back. *Did she just... laugh?*

Indeed, Undyne then started howling with laughter.

"If you..." she then started saying, showing her biggest smile. "If you think I'm gonna give up hope, you're wrong. 'Cause I've... Got my friends behind me."

Frisk grimaced at her.

"Alphys told me that she would watch me fight you... And if anything were to go wrong, she would... evacuate everyone. By now, she's called Asgore and told him to absorb the six Human SOULs."

Undyne's body began to melt.

"And with that power..." she gasped out. "This world will live on...!"

Frisk had heard enough. He drew the dagger and ran at her, slashing her head from her shoulders. Upon receiving this damage, all parts of her body turned to dust.

Frisk, standing in the ash-pile of Undyne, wore a worrying look.

"I could barely defeat Flowey after he'd absorbed the six SOULs. What chance do I have against Asgore?" he mumbled. "What am I supposed to do?"

"Kill them all." Frisk heard something reply back in his voice. "They will not be able to stop you."

Frisk's worrying subsided.

*That's true...* he thought. *After all, I killed Undyne with such ease, why not the rest?*

Frisk lifted his chest up. He'd never felt it so heavy before. But it didn't matter. He was here for a purpose. To gain power. With that goal in mind, he was DETERMINED to see it through to the finish. With this, Frisk began moving on to Mount Hot.
