Hey there! sorry that this chapter took a while to get out. School started back up again, so I've been preoccupied with that. I apologize that it's a little short, but this was meant to be a chapter dedicated the the battle with Undyne. Now, on to reviews!

AmirulAmani: Thanks for your feedback! I think I'll stick to keeping my chapters on the shorter side for now, but I might make it a mission to post longer ones during holiday breaks.

Gaster: This story's Chara had a soul of Determination, but it wasn't strong enough to save and load on her own.

A guest: Probably around the same level as Seito's. I'm not using LV to gauge strength in this story, it's only used to quantify how much one has killed, and nothing else.

935114daniellol: Glad you're enjoying it.

Marce98: Thanks! hope you'll stick around!

Anon: Glad your so exited.

Undyne thrust her spear towards Badd's neck at alarming speed. The Bat wielding hero barely managed to react in time to duck under the weapon.

"Heh, nice reflexes! But let's see how you handle this!"

Badd and Seito were suddenly encased in a box made of spears that had sprung up from below them. The all to familiar sound of Undyne's energy spears forming sounded from above them. They looked up to see a shower of spears cascading towards them. With so little room to dodge, they had to maneuver their bodies just right to avoid the pointy objects.

"Tch." Badd grunted, a Spear nicking him in the shoulder.

Eventually, the rain of spears stopped, and the spears encasing the heroes dissipated. Undyne wasted no time in rushing back in to confront them once more.

"Come on Undyne! We really don't want to fight you!"

"You think pretending to beg for your lives will make me lower my guard? Not a chance!"

"No! Ugh, that's not what I meant! We don't want to fight you because we don't want anyone to end up hurt! Regardless of who wins this fight, Someone won't have a happy ending!"

"You think you human scum are at all deserving of something like a 'happy ending'?! You snatched us monster's future away and forced us down into this hell!"

Seito was trying to think of something, anything, that would end this confrontation peacefully. "I know that our ancestors did that to you, and for that, we apologize. We're trying to make it right. We want to break the barrier and give you your rightful freedom!"

For a quarter of a second, a flash of doubt flickered in Undyne's eye before she hardened her gaze.

"You think your lies and mind games will work on me human? You say you want to break the barrier and set monsters free? Then hand over your soul right now. All we need are two more before the barrier can finally be broken."

"Hey Seito. I don't think she's gonna listen."

"Unfortunately, I'm inclined to agree. Looks like we're gonna have to do this the hard way. Again."

Undyne flung herself at Badd once more, two of them dealing and blocking blows so quickly that to Zenko and Temmie, it looked like a blur of motion.

Seito ran up and broke Undyne off as soon as Badd messed up a block. Undyne however, was prepared for this. She thrust her palm out in front of The handsome hero, a bright green glow emanating from his soul.

"What the- I can't move!"

"Hah, that's right human! It's my signature ability! If I can get close enough to a target, I can render them utterly immobile! However, their soul manifests as a shield to protect them. It requires a lot of focus, so I can't keep it up for too long at a time."

"Uh, why did you tell us all of that? We can easily use that to our advantage."

"I may hate you humans, but I'm an honorable warrior. I don't use cheap tricks without explaining them."

"...Fair enough."

"Now, let's see you block this!"

A ton of spears came hurtling towards Seito from multiple directions at breakneck speeds. However, with his natural perceptive eye, he was able to block them all successfully.

"Was that all?"

just as he finished saying that, a yellow spear came hurtling towards his face. Seito raised his soul shield to block, but right as the spear was about to hit him, it bound over his head and embedded itself in his back.

"Agh! That was a dirty move."

"What? You were handling things so well, I thought I'd up the ante a bit."

It was at that point that Undyne couldn't keep her focus any longer, and dropped her hold on Seito's soul.

"Alright! let's get back to it! Give it everything you've got!"

Zenko and Temmie were hiding behind one of the nearby boulders watching the fight play out.

"Whoa! Undyne must be really strong is she's managing to take both big bro and Mr. Seito on at the same time!"

"Yeah! Undyne's the strongest monster in the underground outside of king Asgore. But she's being a big meanie today, and Temmie doesn't like that."

"Yeah... Hopefully Badd and Seito can convince her to stop fighting..."

Undyne was a much better fighter than Badd had originally anticipated. Then again, he supposed Chara's analysis didn't take fighting skill into account. He'd been stabbed a few times in the arms and legs, and had taken a rather brutal kick to his right side. As such, his fighting spirit was starting to kick in.

"Heh, had enough human? Once I deal with your friend, you'll be easy pickings!"

Badd grit his teeth and dashed towards Undyne at speeds she wasn't expecting. He slammed his bat into her midsection, taking the breath out of her despite her armor. The female warrior went flying into the mountain at breakneck speeds.

"Alright! Let's go! Killer move! Pumped up Explosive Strike!"

Badd Slammed his bat into Undyne with quite literal explosive power. She went Flying off into the distance, the mountain crumbling to pieces behind her.

"Badd! What the Hell?! That could've killed her!"

"Chara said she was a dragon. That couldn't have killed her... Could it?"

"Don't worry, she's alive, but very injured. There's no way she can continue fighting."

Everyone sighed in relief, Before heading off to find the downed monster.

"DAMN IT DAMN IT DAMN IT!"

Undyne Righted herself, albeit slowly. That human's power suddenly got much stronger for seemingly nom reason! Was it because she provoked him? No, that couldn't be it.

The sound of running footsteps snapped her out of her musings. They were here.

"What the hell are you made of?! No human I've ever heard of was that strong! How'd your power spike so suddenly."

Badd shrugged. "Determination."

Undyne stared blankly at him for a moment, before she began to chuckle. Soon that chuckling turned into full blown laughter.

"Of course! Alphys told me that humans were determined."

Undyne slowly got back to her feet, clearly struggling to even stay up.

"Undyne, Come on, please stop. You're in no condition to continue fighting."

"But I'm determined too!" Undyne roared. Small sparks of red energy started crackling around her, cantered around where her soul was.

Badd's blood suddenly ran cold. Undyne's legs were wavering, as if they were incorporeal.

"Come on, Undyne, Please! If you keep pushing yourself, You'll die!"

"Determined to end this RIGHT NOW!"

Spears sprung forth and fired themselves at Badd and Seito. However, they were much slower than before, and their points looked significantly duller.

"Undyne, snap out of it! You don't really want to die for some petty form of pride, do you?! Think about all the people who care about you! Think about all the people who look up to you!"

Undyne finally seemed to snap out of her trance.

"Papyrus... Alphys... Asgore... What am I-"

And with that, Undyne fell into an unceremonious heap on the floor, her legs finally reforming themselves.

"Oh thank GOD."

It was then that Badd's phone started ringing. Recognizing the number, he picked it up.

"HEY! HOW'S IT GOING? I WAS JUST THINKING, YOU GUYS, ME, AND UNDYNE SHOULD ALL HANG OUT SOMETIME! I THINK YOU'D MAKE GREAT PALS!"

And that's a wrap! Next time, the crew go to Undyne's house to patch her up and hopefully befriend her in the process.
