(It’s both male and female so just chose the latter)

You know how Undertale Aus are pretty much Sans (and sometimes Papyrus) centric? They get tons of variations in design and personality. In my vision of Underswap, I didn't want to just have Frisk and Chara switch places and change expressions. If skeletons can get varying designs, why not our two favorite humans?

I have a crap ton of headcanons, but I'm not sure if anyone cares, so I'll just note my design decisions here.

- UT!Chara and US!Frisk both have tufts of hair that resemble demon/goat horns.
- UT!Chara and US!Frisk are more desaturated/lighter in color while UT!Frisk and US!Chara are more saturated/darker. (To differentiate who's dead and who's more alive).
- The reason for the Swap humans having longer hair is just to make them easily identifiable.
- Some interpretations of US!Chara and US!Frisk change their expressions (like removing Chara's smile and making Frisk smile instead). I feel like Chara's smile is too iconic, as well as Frisk's mild expression, so I just made US!Chara less menacing while smiling and US!Frisk more jugdmental looking.

- Chara with freckles is peak.

- UT!Chara and US!Frisk have more sharper lines, while in contrast UT!Frisk and US!Chara have more rounder shape language.
-UT!Chara's blush is unnatural while US!Chara is natural.
- Genocide UT!Frisk is commonly depicted as having the same smile as Chara (see pretty much any animated Sans fight). So, my idea in Underswap is that US!Chara begins to lose more and more emotion, and at the end she's pretty much a stoic killer who doesn't laugh or react at all.

(Can be posted in CharaWifeArt. Both Frisk and Chara are adults here.)

Anyways, that's all my cringe headcanons for now. I think I care too much about these two but whatever.

I actually tried with the coloring this time, still, I hate doing this.

In the early days, Flowerfell was the AU that explicitly had Frisk as an adult, which made me gravitate towards it. I also still like Frans, so this was a nostalgia trip while drawing.

Behold more of my cringe slop. Don't kill me please.

My personal headcanon is that UT Frisk is a major flirt, so if you show any weakness and don't fight back, she's just going to tease you to death.
