Make It Possible [Underverse]

X-3-X

Ink was the first one to step out of the glitchy portal, immediately freezing afterwards. Error nearly bumped into him as he was stepping forward, literally darting to his left to avoid contact with the shorter skeleton, only for his eye sockets to widen as soon as he noticed what was amiss.

Everybody was either on the ground or trying to stand their ground against...
X-Gaster and a few more characters from X-Tale. Excluding Cross and Chara though, Cross wasn't there for obvious reasons, while Chara was fighting... Kinda. X-Gaster was occupied with the remaining Fell!Sans.
The chalk-like coloured kid was currently on the ground, wounded heavily, as X-Mettaton swung his saber, ready to strike.

Time seemed to slow down for the two skeletons as they stared at each other.
"LoOks LikE yOu'vE gOt a BiggEr prOblEm on yoUr handS now..." Ink heard Error speak, though it seemed slightly muffled to him.
He had no idea what to do, he didn't even have his brush-

Ink gripped his paintbrush tightly, confusion dawning on his skeletal face as he wondered when'd he get it... He had a feeling it was destroyed before...
Well, it didn't matter now...
X-Mettaton hasn't striked X-Chara with his weapon yet...
That got the Creator thinking...
What should he do?
Should he stop X-Mettaton?
Or should he attack X-Gaster right away and let the robot take care of the first problem?
Or maybe he should ask Error for help?...

No.
There's no time for that.

Ink's left pupil turned into a red target, while the other turned into a single red pinprick.
His body moved before he could think about it. But as he did, he thought of everything.
The things X-Gaster and X-Chara stood for. What both of them did. To him, to the Multiverse, everyone.
At first he was running in the direction his legs carried him, but then, he sidetracked and jumped into the air, swinging his paintbrush...

To block the robot's saber, his own weapon acting like a sword. He had no idea how the wooden structure survived the blow from the laser of the blade, but he was glad it did.
He grunted, quickly shoving X-Mettaton away from himself and X-Chara with a push of his paintbrush, only now noticing how singed the handle has become. He could hear the surprised exclamation from the boy behind him.
And then, he saw Error appear next to him out of the corner of his eye socket.

"WhAt iN tHe wOrlD aRe yOu dOing, yOu idIot?! YoU couLd'vE jUst lEt tHat dAmn roBot kilL the kId!" the black skeleton yelled at him, his voice glitching furiously, making it barely understandable.
"Error, you said it yourself- we've got a bigger problem than Chara now, and that's X-Gaster!" Ink exclaimed, his paintbrush still inna defensive position just in case the robot comes at them again. "And I know that even if I had tried to attack him, he would've still overpowered me, despite his current power!"
"YoU'rE aN iDioT, InK... hOlY FU-" Error got cut off by the need to dodge the saber of X-Mettaton. The black skeleton growled angrily and quickly used his strings to throw the robot far away from them so they could talk. "So, aNywAyS, wHat dO wE do NOW, gEniuS?!"
"I don't know, I'm improvising!"
"YoU!-"

"I'm still here, you morons!" the two skeletons turned their heads at the sound of X-Chara yelling. The boy stood up slowly, dusting himself off and crossing his arms. "It's obvious that Gaster is improvising as well right now, after all..." he glanced at Ink. "One of his greatest assets has betrayed him..."
"So, what do you think we should do?" Ink asked, starting to lower his paintbrush slowly.
"Well... Look out!" X-Chara suddenly exclaimed, just in time for Ink to see the Asgore from X-Tale charging straight at him.
But he got stopped literally inches away from the short skeleton by blue strings wrapping around his soul and throwing him in the same direction X-Mettaton was thrown in.

Error huffed, his shoulders slumping.
"HoW maNy tImeS wIll I hAve tO dO thiS tOdaY?!" he groaned.
Ink blinked a couple of times.
"You... Saved me..." he uttered out, looking at Error in shock.
"WeLl, SomeOnE hAd tO! PlUs, I wAnnA sEe wHaT yoU're GonNa dO!" the said skeleton crossed his arms, rolling his eyes... Somehow.
"Hey, boneheads! You wanna know how to defeat X-Gaster or not?!"

The two skeletons immediately turned their attention to the kid, Ink simply looking at him with interest, while Error literally glared.
Chara exhaled loudly.
"Soo... Here's what we're gonna do..."
