The shadow did not respond, but then a chuckle went through. "Heh, classic of peeps who Ive never met!"
The shadow poofs out a moderate hight, but slightly skinny, pale skinned peep. More details later

"* So, I see you're all different AUs of Sans, our classic rib tickling comedian!"

(...Hm. Should I do 'Canonical' Blue who likes puns or 'Fanonical' Blue who doesn't...?
....Imma go with canon.)

Blue cracked a puzzled smile, then decended into a fit of giggles. "That was unexpected...Mweh heh!" He chimed, eyelights twinkling with mirth. He dismissed his attacks and stepped forward, eagerly extending a gloved hand in greeting.

"Hello there stranger! I'm known as The Magnificent Sans, Well-Respected Royal Guard, but you may call me Blue. How about yourself??" He asked in a warm, welcoming tone.

Error made an agitated noise, form flickering as he sent down a barrage of bone attacks before landing.
---

Crow spread out a wing in front of Abyss, signaling for him to wait for Cosmo to gather himself. A minute passed, and Cosmo had caught enough breath to speak coherently.

"Error's still out on the ridge, but he's fighting something now. I didn't get a good look, but whatever it was? It was big. I think you guys should clear outta here; they might accidentally tear this timeline to shreds."

"well, after you state yourself and your business, could you say what you think happened here?" currence asks.
------------
"that isssssss jussssst a ssssssssample of my power. however, I wouldn't mind having another sssssslave." the snake says as it warps space, bringing error cloer so it lunges at him.
---------
"that sounds like it's a monster. i mean, it has to be strong, the only people who could face error are me and ink." abyss says incredulously.
( where's ink? wouldn't he sense the outertale timeline ripping up?)

Blue briefly glanced at Currence and pouted. "Be nice,"
---

Error narrowed his sockets, opening a portal behind him and backing through. He was about to collapse it behind him when an interesting thought crossed his mind; What would happen if I closed if when he's only half way through? He glared at the serpent, then smirked. Only one way to find out...!
---

(Well, the blank AU was giving Ink chills, so he ran off to try and do something about that. Now he trying to figure out where Blue and Currence are. Outertale's timeline is gonna be fine, Cosmo's just being cautious; He's aware of what Error's capable of.)

Cosmo shrugged. "I know. But if Error is getting a rush if adrenaline in his marrow? I think it's best if you get outta here, at least until he leaves, just to be safe."

"sure." currence says with a shrug
-------
the snake lunges through the portal after error.
-------
"that's a very good point." abyss says as he opens a portal.

Crow blinked, then nodded, folding his wings over his shoulders and looking back at Cosmo. "Hey, thanks for everything."
Cosmo responded with a grin. "Hey, no trouble at all. I wouldn't leave a guy hangin', much less myself, heh."
---
Error grinned, then closed the portal as soon as the snake tried to persue.

"goodbye, then." abyss says as he walks through.
--------
as the portal closed the snake appeared next to error. "you can't pull that little trick on me." it says.

Error shrugged in response. "Maybe not, but was it worth a try? Absolutely."
---
Crow followed Abyss as Cosmo waved a farewell. "Take care of yourselves,"

"* Oh, I know who you are, you little blueberry. The names Midnight, and I, uh, dunno how i ended up here."

Mid sighs. "I notice that there are some rifts in this timeline. I dunno how, but I can check an AU's condition."

He summons his scythe, and spins it with a finger, out of boredom. "Is there nothing to do here?"
