"Yo…" Rex murmured as they looked up at the fusion. "That tackle was really good-they wouldn't have known you were there if you weren't yellin' while you came down." The younger one's gaze swiftly moved back to their surroundings as they kept close to one of the buildings.

Rex hadn't spoken much since they entered, but they had found an odd moment of quiet amongst all the chaos. Though-quiet didn't mean silence, as they could still hear the fighting in other parts of the cavern.

"I know, right!" Kid enthused, ruffling his wings in excitement. "It's kinda hard to manage though, I don't really know my own strength. I kinda wish we'd practiced with this form beforehand..."

Keep focused, Kid, Chara warned.

"Yo, at least you didn't learn you had the form in mid battle like I did with my magic…" Rex glanced back the way they came, frowning a little...something didn't feel...right. It reminded them of fighting the red-eye… They shook their head and continued, talons digging into the ground.

"Yeah," Kid glanced about as surreptitiously as he could at his new seven-foot height. "Yo, what do you think that screaming from earlier was about? It didn't sound like the fighting we've been hearing…"

"Dunno…" Rex mumbled. "That was just...yelling-unless there's some stray beasts that got in here…" The child gave an odd shrug of their shoulders before pausing at an entrance to another building. "Yo…"

Kid blinked and looked up at it.

Looks like that's the main complex, Chara noted within Kid's mind. The good news is, most of the people who would normally be there have probably been drawn out by the fighting. If nothing else, we should at least find out where they are.

Kid relayed what Chara had said to his counterpart, adding; "I just hope the ceilings are bigger in there, haha."

Rex gave a snort, tugging on the door with their magic, groaning a little as they stepped back. "Stupid...heavy…"

"Here, let me help." Kid stepped forward, raising a foot and jabbing it forward, sinking his talons into the metal door. With a mighty grunt, he pulled it off it's hinges, hopping back a few steps to keep his balance. He grinned widely at his counterpart.

"Yo! That was awesome!"

You could have just nudged it open, Chara sighed, a fond smile playing across her image's features despite her words.

Rex looked to where the door had gone, their tail wagging a little as they jumped with excitement. "Yo! Undyne's right about doors!"

"I know, right!? I've never been strong enough to take a door all the way off before though! Aw man, wait till she hears about this!" Kid shook his foot to dislodge the door from his talons… and frowned.

The metal door clanked off stone, but was still lodged in his claws. He shook it again, trying to dislodge the unwieldy thing, flapping his wings in an attempt to keep his balance as he did so. Still no luck.

"Ummm…"

Rex was trying so hard not to laugh, though their smile showed up regardless. "Yo…uh..." They stepped forward, inspecting the odd situation.

Kid managed to put his other foot down on the metal door, using it as leverage to pull the other one out. Unfortunately, he forgot to raise the claws on that one and, still unused to his power, ended up getting those claws caught in the door as well.

"On second thought…" he looked down at his little counterpart. "Maybe we don't tell Undyne about this."

Oh my god. Chara buried her face in her hands. I'm in love with an idiot.

"We could just leave this part out," Rex suggested as they came forward, concentrated on where Kid was stuck, before the fusion felt something around his foot as the child attempted to help gently.

Between Kid and Rex's efforts, they managed to unsnag one foot, at least. As they began to work on the second one however, Chara cried out a sudden warning.

Kid!

The fusion whipped his head up, to see a shambling horror of a creature appearing in the doorway, surrounded by a purple aura.

"Rex, get down!" he shouted.

The little one yelped, already diving away from it, tripping, but as they stumbled, they managed to catch their balance, turning in alarm as they looked at the abomination.

The creature let out a screech, but Kid didn't give it time to do more than that. Following Chara's mental instructions, he called on his magic and breathed a gout of flames at the creature. The fire smashed into it with physical force, sending it flying back into the building where it slammed against a wall and slumped to the ground. The purple aura dissipated around it.

Kid breathed heavily, his eyes wide.

"Yo… what was that?"

"I dunno," Rex managed. "It looked like something from a ghost ship…" They shuddered. "Creepy…"

Kid's red eyes narrowed.

"C'mon, help me get this thing off… we should probably be careful if there's more of those…"

"Yo...right…" With that, the child hopped to it, quickly aiding their counterpart. "Mmmaybe don't tear doors open till we need to…"

"Yeah…"

It wasn't long before they were able to get Kid free of the door, and the fusion flexed his claws in appreciation before kicking it away with a clatter.

"That's better. Let's get going then…"

The two entered the building, Kid taking the lead. The halls and ceiling were wider and taller than some of the buildings they'd been in before, though Kid still had to duck his head a little to keep his head-spikes from hitting the ceiling.

As they passed the smouldering form of the creature Kid had dealt with, a hand suddenly shot out, grabbing at Rex's leg with a screech, purple magic emanating from its fingers.

A shrill cry escaped the young one as they whipped around, lashing their dagger down on the limb as they tried to frantically pull back

The weapon sank deep into flesh and glanced off bone, but, if anything, the abomination's grip only tightened, its magic crackling along Rex's scales. Kid was trying to get himself fully turned around so he could see what was going on, but even in this wider space, he was still having difficulty with his form.

"Rex!"

The child was struggling, trying to wrench back on their good leg, their magic desperately smashing the weapon back down-trying to pry the fingers off.

Hacking desperately at the creature's arm, they managed to sever the limb completely from the body. Blood and pus dripped from the stump, and though the magic stopped affecting Rex, the hand still refused to let go.

The abomination did not appear capable of getting up, fortunately for the child. It screeched and spat at them, magic still crackling around it's body, but made no move to rise.

Rex hopped away, yelping as they did, before raising their leg, desperately prying at the hand with their magic as they shook it.

Kid, finally having managed to get himself around, spat another burst of flame at the abomination. Its shrieks and wails increased for a moment, and then there was silence.

"Yo, are you okay, Rex?" he asked, crouching down and looking at the child in concern.

"Get it off!" Rex managed, shaking their foot, and yelping in the process. The purple stained their leg, almost looking like a bruise.

"Yo, hold still." Kid grimaced, then stretched his neck out and grabbed the arm with his mouth, pulling at it and finally yanking it from the child's leg. He spat it out immediately, continuing to spit in an attempt to get the taste from his mouth as he scrunched up his face in disgust.

Rex leaned against the wall, inspecting the darkened scales with concern. The limb shook slightly as they slowly put it back to the ground, breathing out harshly as they tried to deal with the pain shooting up their leg.

"Oh god… that was so gross!" Kid smacked his lips, trying to get rid of the remnants of the taste. "Eww." He shook his head violently. "Yo… I thought he was dead! And then he just-" He cut himself off and looked at the child. "Yo.. Rex…"

"Purple magic," Rex muttered, stepping forward, though they swiftly kept the majority of their weight on the uninjured leg, wobbling slightly. "I'll be okay…" They were putting up a front-it hurt, but...they had to find Frisk.

"You don't look okay." Kid examined the wound on Kid's leg. "That looks like it hurts a lot."

"I'll be fine," Rex insisted. "Let's just find them and get out of here before something else shows up…"

Stubborn kid…

"Just follow close, okay?" Kid voiced his concern. "And let me know if you need a break, you won't be able to help rescue Frisk if you're too badly hurt."

Rex nodded, looking about, before moving forward, keeping to the wall, and using their shoulder to lessen the weight when they put the injured leg down, though now the child's eyes were narrowed in concern.

Kid moved forwards first, both his and Chara's senses on high alert as they kept an eye out for more of those things. So far, there hadn't been any. But…

There were more bodies lying about. All Humans wearing uniforms… probably. It was hard to tell as both uniformhad been basically shredded. In the distance, they could hear more screeches, probably from more of those things, but at least for now it didn't seem like there were any nearby.

Rex swallowed, feeling a little sick. This was the first time they had ever been near any bodies like this, and...the stench was horrible on their sensitive muzzle and it sent shivers down their spine.

They hobbled after Kid, ignoring the throbbing pain on each step they made, their stomach churning as they continued on their way.

There were many doors, many hallways. Kid and Rex both did their best to search through them all, while hoping to avoid any more of those creatures. Kid was taking things slowly for the sake of his counterpart, while Chara did her best to keep Kid from noticing the stench permeating the building.

As they were about to round another corner, Rex halted, hearing harsh noises coming down the other hall. They swallowed, readying their dagger as best they could. "Yo…" they muttered softly.

"I hear it," Kid replied. "Be careful, alright?"

They cautiously looked around the hallway, which ended in an open, bloodstained door with another body slumped by it. The sounds seemed to be echoing from beyond the door, which lead to a stairwell.

"Uh, yo, we sure we want to go down there?" the fusion asked, rolling his shoulders and shifting his wings nervously, the motion causing the chains wrapped around his torso to clank against each other. "It's probably not gonna look very good…"

"Don't want to, but…"

"Guess we gotta look everywhere, huh?" Kid groaned quietly. "I don't know what those things are, but this whole thing has seriously become a whole lot less cool since that one showed up."

Rex nodded their agreement. "I think I can make a shield, if we need it...but...maybe we'll luck out…"

They tentatively made their way down the hallway, though Kid paused as he reached the door.

"You gonna be okay on the stairs?"

Rex made a low sound and then looked up. "Well, if we can see the bottom and you don't mind going down the stairs twice…"

Kid's crocodilian muzzle twitched into a smile.

"I think I can manage."

A few moments later, they were both at the bottom of the stairs, staring down the long, dim hallway with cells lining the walls on either side.

"Hey!" Kid perked at the sight. "Yo, this might be it!"

Rex looked ready to sink down in relief. "Thank you…" they moaned before looking around for signs of their friends-or danger.

There were growling noises coming from somewhere, though neither of them could see where. As well, they could hear the sound of metal screeching and clanking.

"That's not good..." the dark-scaled fusion murmured, keeping his magic at the ready.

Rex sighed, raising their dagger as they kept close to the fusion, sparing their leg as much as possible as they nervously continued down the hall, looking for the captives-or the source of that horrid noise.

About halfway down the hall of empty cells, there was a T-intesection exposing a new hallway. It was here that the two found the source of the noise. Three more of those abominations were bashing and smashing at a metal door, apparently trying to get at something inside. There was a fourth one, but it lay unmoving on the ground next to a bloody Human body.

"Stay back," Kid warned, hunkering down. "I've got this."

Rex nodded, going back behind the corner, poking out just enough to watch in fascination as the fusion went to handle the threat.

One of the creatures noticed the fusion dominating the middle of the hallway and switched focus, beginning to tear towards him while the other two focused on the door. Kid widened his stance; he'd seen the damage these things could do and didn't intend to let them cause any more harm.

After what we saw of the last one, I don't think letting them live is an option. Chara murmured, almost reluctantly. Make it quick.

With that, Kid opened his maw and let the fire pour forth. White hot flames, tinged with red, poured down the corridor in an inferno. Due to the enclosed space, the fire congealed on the walls and pushed together until the entire corridor in front of him was filled with his fire.

After a few moments, he released the magic and closed his mouth. The fire dissipated, but left behind scorch marks all across the walls and ceiling. All that was left of the bodies and creatures within, were charred skeletons.

Kid panted in the wake of the magic.

You might have gone a little overboard there, babe.

I had to make sure they all died, Kid replied mentally.

Still, that took up a lot of magic. We've still got plenty, just be careful about pulling that stunt again, okay?

"Yo," Rex called. "Coast clear?"

"Y... yeah," Kid managed, trying to compose himself. "Looks like…"

Rex paced forward, and looked around. "Frisk!" they called. With the rest of the ruckus going on, if anything else was to come-it would already be on its way, regardless.

"Rex?" came a concerned, scared tone.

The little Monster went stock still, before bolting forward.

Kid quickly followed after the child, relief surging through him.

"Little Frisk?"

"Over here!" Another voice called, before they heard a click of a key in a lock, and out stepped a ragged looking William, cradling Frisk in his hold. Rex stopped in front of the Human, stomach churning as they noticed the fabric covering Frisk's eyes.

The little one growled angrily, realizing what had been done. "Rex…" Frisk mumbled as they turned toward the noise.

Kid frowned in concern at the little one.

"Are you guys okay?" he asked, kicking himself mentally a moment afterwards for asking such a stupid question.

"Drained," William replied. "But I can worry about carrying Frisk."

"Frisk…" Rex mumbled worriedly.

"We'll be okay," Frisk promised. "But um...don't hurt Blue…"

"Who?" Kid looked around in confusion, suddenly a little self-conscious about how different he looked now.

"I think you can come out," William said in response.

Warily, a third Human stepped out, both hands raised to show he was unarmed.

Rex jumped back on their good foot, and then looked up. "Is this the same Blue you mentioned…?"

"Uh-huh...he's helping more…"

Rex made an uncertain sound, fidgeting. "Friiiisskkk…"

"Yo… are you sure?" Kid looked down at Blue, red eyes narrowing dangerously while Chara practically hissed at the idea they should trust this Human.

The blue eye kept his hands up, though said nothing in his defense. William turned, red eyes dim and tired. "He's helped us," William assured.

Kid shook his head slowly, then refocused on the prisoners.

"Where's our Frisk?" he asked warily, stepping forward and peering into the cell to see if his friend was there.

William shook his head. "I'm afraid he's been taken to another building."

Rex moaned. "He's still in danger…"

"The security there is tight," the blue eye stated. "But with those things running around, that might work in his favor…"

"What do you mean?" Chara shifted uncomfortably in Kid's mind, but remained silent.

"It seems Overwatch wants to regain their magic," Blue stated carefully. "They've been using our-and leftover Monster magic that they took to accomplish that...the boy is their test subject for this."

Chara rose within Kid's mind, screaming bloody murder. The boy flinched and raked his claws against the concrete, trying to resist the bloodlust she was awakening within him.

"Chara…" he let loose the soft name, not realizing he'd even said it aloud.

Rex turned worriedly. "Yo…" The reptile than glanced to the Humans.

William frowned. "We either stay here, or get out on an escort. The danger seems to be escalating if the sound is anything to go by." The fusion's ear fins twitched, but otherwise, they remained silent.

"We need… to get Frisk… out," Kid managed, barely making out the words while trying to calm Chara mentally. It was difficult though, she seemed to be igniting his own anger over the situation somehow, making it hard to resist her will.

"And while I trust you have the capabilities," William started. "I and this little one will only slow you down...and it looks like Rex should be staying out of future fights."

"I can manage…" Rex muttered.

"You can manage leaving," William stated sternly. "Look, danger is coming into this building, making it no longer safe. If we can get out somewhere secure, you can return down here to find him, instead of trying to watch over us at the same time."

The brown-scaled reptile growled his discontent, his wings twitching uncontrollably.

"There are dangerous things running about," William continued. "I know you want to go and find him now, but it's not worth risking the injured or defenseless. As soon as these little ones are somewhere safe, you can come back."

He's right, Chara, Kid all but begged mentally. We can come back.

What if he doesn't have time? He could be dying! He could be dead!

We'll find him, I promise.

Chara still fought him, But Kid found that, somehow, he could override her will. Not that she made it easy on him.

"We have to go fast." Kid's eyes refocused. "Can you run?"

"For a while," William assured, while Blue looked down at Rex.

"This one needs to be carried."

Rex grumbled, but nodded, while the little fusion made a hum of concern. "Here," the other Human replied, picking the reptile up. "Should be good to go."

Kid began hurrying away, opening his mouth to speak, but he stopped stock-still at the sudden sound of shrieks and screeches. They were closer than the distant sounds of battle… it sounded like they were… coming down the corridors…

"Yo, you guys! Get back in the cell!" he called. "There's more of them coming, I can deal with them, but you gotta be ready to run when I'm done!"

Frisk yelped as William whirled, dragging the other Human in after him while the fusion covered their ears-not wanting to hear what would soon follow as the red eye slammed the door shut, leaving Kid to fend against the incoming dangers.

Sure enough, several of the abominations came around the corner, crashing into the walls as well as each other as they tried to regain their footing.

Kid snarled at them, backing up so that he stood just outside the cell door his friends were in. Chara's anger washed over him, and he clenched his talons while breathing in deeply as the abominations charged. Magic was flung every which-way, but even the shots that landed still barely registered to the angry Monster.

"Let see how well you handle my Special Attack," he growled, before releasing his energy. Unlike in his normal form, he had so much power flowing through him in this fusion that his Special Attack did not require charging at all.

Stars the size of basketballs flew from his mouth in a haphazard pattern, each one surrounded in an aura of orange or blue flames. They rocketed down the corridors, smashing into the mass of flesh that shrieked and hissed at the attack.

But it seemed that something else changed when using his attack in this form.

Unlike before, every time one of the stars impacted a wall, or an abomination, it exploded into a bunch of smaller stars that flew out in all directions. Kid stared in awe at his own handiwork. Between the confined space and his new power, the abominations were shredded before they got anywhere near him.

He shook his head violently, then tapped the door with a talon.

"Yo, let's go before more come. But I think we should see if we can find another way around..."
