Genocide Relationships~ (Underfell)

So that's my Beta Frisk :3c
She's the genocidal Underfell creature that can be seen in my Control MV fav.me/d9jpiu0
Instead of Chara possessing you, Asriel has taken control. In this picture he's dormant, and Frisk's in control...either way, Frisk has killed all the monsters up to Sans, and has fused with their SOULs. All can be seen in featured in her design~

Also, this is sort of a yandere ship, I'm not sure. Sans is more of a prisoner XD
In the Pacifist route the roles are reversed. 

...idk
just take this garbage doodle I bothered to color.
