*It's you!

[dustless]

• Frisk is nonbinary. 
• They're around nine years old.
• They lived in a neglectful home. They know how to cook for themselves a bit as a result, and know a few illness/hangover remedies (for other people).
• They're pretty tough emotionally, but they function best with a comfort object, even if that happens to be a stick/burnt frying pan/etc.
• The fallen child has been forgiven, even after No Mercy runs. Frisk is at least somewhat aware of the player, even if they can't comprehend exactly what they--we--are. The player is who woke them and pulled them down the path of hatred and slaughter, and Frisk doesn't blame them for it.
• Sometimes they have trouble talking, so their sentences tend to be a bit short. Their vocabulary is relatively wide for a child their age, but they have trouble coming up with words mid-conversation, which can result in awkward pauses.
• They don't know how to swim, but they're willing to learn!
• They were raised by their biological mother; their biological father died when they were too small to remember him.
• They were left alone for about a month before heading to Mr. Ebott, and nobody really...noticed. Their mother already shirked her responsibilities and Frisk has problems telling people things without being asked.
• If left alone too long, they deal with unreality issues--not being sure if they're actually real at all.
• That's why they went to the mountain in the first place, in fact. There was still legend about monsters being beneath it, but monsters aren't real, right? So that's the perfect place for someone who isn't real to disappear.
• They had an irrational fear of zombies pre-fall. Post-pacifist, this expanded into a fear of being eaten, since Muffet's pet and Lemon Bread killed them that way a lot, and Photoshop Flowey's teeth were the thing they had most in their face during their fight.
