NM!Swap Sans Ref Sheet
Honestly, I don't really like how it turned out, so I might redo it at some point in the future. For now, this is what I have.
NM!Swap has six tentacles, with two being a part of his bandana/scarf sort of thing. The rest of his tentacles protrude from his back. He's also considerably taller than a normal Swap!Sans, standing at 5'8ft with his heels and 5'5ft without them.
NM!Swap is rather cynical and very pessimistic, delighting in dampening the mood and creating discord between people. He isolates himself from others and considers himself to be truly 'free' from his old, 'weak' self. He doesn't like thinking about his transformation into his current form and tends to dodge questions about it if asked.
NM!Swap is very good at keeping secrets, especially his own. And he's learned to harness his powers rather well, experimenting with what he can and can't do. And because of his training before, he's only gotten better and is a very skilled combatant, using a mix of his tentacles and goopy bones to fight. He can't do Gaster Blasters anymore though, and is no longer restricted with other abilities he might have had before.
For now as a lastly, he has a major sweet tooth and his guilty pleasure is any sort of candy or pastry every so often. He lets no one know though.
I can't think of what else to put atm, but if anyone has questions, feel free to ask!
