In here, the characters (including frisk maybe) change ages. Basically, if they were old, now they're young, and vice-versa. This probably radically changes the storyline as their personalities would alter with their age. Asgore and Toriel would be children and Monster Kid (...?) would be , like, 90!
(I could not, for the life of me, find a picture of this that wasn't kindertale! That's really annoying.)

Undertale AUs (in my opinion)
AcakHi! This is a random idea I came up with, and in it, I'll be listing every undertale au I know of, and (at least) every main character within them. In my point of view, of course. If anyone wants to share their views on any of them then fine by me...
