Mask morphs into different forms across the multiverse

Is that Underswap!Undyne?
HUH, I'M GASTER? FROM WHAT TIMELINE?
I THINK I BETTER LEAVE...

I don’t even know which Undyne it is. I just saw the sprite, was like “yep, I’ll save it” and done

Understandable. Judging by the fact that she has glasses and seems overly nervous, I'm guessing it's Underswap.

Most likely, but why she look like a teen?

Hmm... Deltaswap? idk

Welp. We both don’t know. I got egg sans and lamp sans now as sprites, as well as all the monsters from all the regions in UT. Including WOSHUA!

Wait us that... PEPMASK?!
