I've been cooking this chaotic little gremlin for a while (since august 18th 2025) and I'm SO excited to finally share him with yall on tumblr!! Say hello to Offend Sans ā the ultimate catboy disaster from the UnderSegments AU!! š»
Appearance:
Classic white skeleton with a single glowing red left eyelight (right socket empty and dripping black like ink tears)
Red ecto-flesh below the ribs ā soft abdomen, hips, and all the fun bits (heās hermaphroditic like some Sanses š)
Crimson red bands on arms/legs
Often in oversized hoodies (sleeveless or with fake cat ears), shorts, and slide slippers ā total comfy chaos king
Personality & Vibes:
Chaotic gremlin energy 24/7 ā he is loud, obnoxious, attention-seeking, boundary-pushing
Screams random words, sings badly, steals EVERYTHING (chocolate, knives, hoodies, your heart)
Super needy ā purrs when happy, bites shoulders to say "I love you",
Deep down? Abandonment issues and a big soft spot ā he just wants to be kept forever
Calls Killer "daddy", Nightmare "boss-dad" ā found family with the Bad Sanses gang!!
Abilities:
Shapeshifts into a small black cat (perfect for sneaking and cuddles)
Summons crimson glass shards as weapons/shields (they spin like deadly confetti)
Can teleport/shortcut anywhere (even restricted realms ā sorry Dream š)
He's my baby and I love him so much ā he's everything I wish I could be: loud, unapologetic, and loved anyway!! š¤
What do you think? Want art? Headcanons? Drop asks or reblog with your thoughts!! Iām posting more renders, stories, and chaos soon~~
