>Undertale genocide run ends
>Chara!Frisk is satisfied with their massacre and leaves the underground for parts unknown, searching for a place where they can finally be free of both humans and monsters
>The few survivors (Burgerpants, Annoying Dog, Jerry, Bratty, Catty, etc.) manage to gather and form a small settlement
>Centuries pass as they repopulate the monster world
>Eventually the Fallen Child and those brave few who died fighting them are forgotten, but hate and fear of children remains
>When the Core finally falls apart due to lack of maintenance, monsters are forced to find alternative energy sources
>A small startup company invents portal technology that can be used to bypass the barrier in search of energy sources
>The monsters are just as bad at naming things as Asgore, and just decide to call their company "Monsters, Inc."
