So ask you can see, this will be about Understack Frisk, Chara and Sans. So I'll type up the description I wrote for it just in case.
Frisk
-------
She is the same but can bounce of walls and stuff
Genocide Frisk
~~~~~~~~~~~~
Dones t glitches into Chara, but has visible glitches around her. Still the same though
Chara
---------
Nice, sweet, innocent and helpful. Each time Frisk "stacks" her determination, it brings a price of Chara back
Chara evil
~~~~~~~~
Same but very glitchy when meeting
*too lazy to make glitches* *XD*
Sans
-------
Still loves puns and ketchup but likes to stack up
Sans Power
~~~~~~~~~
Same but with some new powers *add later*
So that's it but the other 6 will come. Love ya!❤️😄😜😎
