Underswap Frisk ain't got chill

Got that, you smiling dumbass?

Edit: added blushes to Chara to clear up any confusions. sorry 'bout that

I just got this idea from listening to mash up tracks. and also I'm sleepy af
I imagine Underswap Frisk as an older sister figure to Chara, a manipulative and threatening older sister.
Honestly she did that 'cause she's tired of all the humans dying and she likes Chara as a little sister.
Or she really has no chill. She a bitch like classic Chara and will be pissed off if someone kill their human vessel.
Up to you.  the ceiling hehe
