Penny Toons

A world of Undertale that is very familiar, yet somewhat not. Monsters have been freed from their exile underground by Frisk. Asgore has begun running a settlement on the surface, but many monsters still choose to live in the mountain in the decade that has passed since the barrier's fall.

This universe is one where monsters, magic, and so much more are expanded upon to give them more realism and intricacies. A good example is the Flowey of this universe. A Golden Graverose is the monster classification he decides upon after getting proper sun and care as a plant monster on the surface. He's still quite the fussy flower, but at least he isn't murdering anyone.

New locations within the underground are added as well. Such as a volcanic hot springs on the border of Waterfall and Hotland. And one must not forget the temple to the angel and the museum of monster history in New Home.

Everything appears full of great potential for growth, but every story, even one like this, needs a conflict. That's where The Chasm comes in. With the barrier having been destroyed and everyone settling into a new daily life, something strange has appeared. A brand new powerful force to overcome. Dubbed The Chasm by those not wishing to call it The Void, it is a break in reality that appears and disappears at random, spitting out people from other universes at times. Sometimes it causes strange phenomena or releases dangerous beings known as The Corrupted out into the world.

It seems to have started to appear after a screaming lunatic calling himself the royal scientist dragged himself out of the far depths of Waterfall claiming to have clawed his way into existence. He seems able to open and close The Chasm, but this isn't something he can do on a whim or by his own volition.
