Underswapalphys Stories

As usual, Sans comes back from training, happy and excited, except this time, he arrives home 'marked'. Papyrus is not pleased, until he finds the creative little secret his brother was trying to hide~ Set in Underswap Universe.

[Underswap Papyrus x reader] You have a secret. You are the last of your kind, shapeshifter / Human hybrid. The very culmination of your being constantly pleads for you to be honest about who you are, but your kinds law prevents you from doing so. Will you be honest and open about your powers with your new friends, or will you continue to lie and hide in the dark? (Yes the title is a pun, if you aren't aware bonafide means honest/ trustworthy, yes the title contradicts itself it's supposed to show the struggle between logic and emotion.)

After months of not being around anybody much since Undyne was recovering from almost dying. She's been so afraid that she would hurt everyone she loves and cares about because of her losing so much control. She feels like her soul was breaking once again and she didn't know what else to do. After a accident while she was sleeping and almost killing Alphys and Frisk she runs into the ruins and stays there. What will happen if she loses control? Will she be able to stop it or will someone we know take control over her. Another war is at stake in the Underground and with Undyne nowhere to be seen or heard from, monsters were starting to panic. Will Undyne go back to herself or will she be someone else?
