Frisk: ???

Toriel: ???

Flowey: ???

Sans: Bittax

Papyrus: Crumple

Undyne: Aya

Alphys: Some random au of Bittax

(This next one isn't 100% certain but I might add this)

Mad Mew Mew: Emma

Asgore: ???

Asriel: ???

Mettaton: Armi

Mettaton EX: Armi (but better)

Mettaton NEO: Armi (but in a cool pose)

The Alphys choice was made because Bittax is dating Aya and I didn't want to put some random uncannon ship that doesn't exist in the mod

If you have any ideas for the others then let me know
