sans is a skeleton that has very interesting and powerful powers, sans is originally from the famous game called undertale. soon there will be more updates and if you want leave me comments to add something you want me to put.please do not steal my addon or edit something to look like yours at least ask me for permission.
In this little update I added three different types of sans (dust sans, xans and error sans) let's meet them...

Changes were...
- add to dust sans, xans and error sans
- slightly change sans texture
- add music
I'd suggest giving sans 1 HP but try coding in a "dodge system" that prevents him from taking damage until around 23 hits. His attacks deal 1 damage, and rely on quick poison damage in the form of KR. to mimic this, make his attacks deal 1 damage but inflict Wither III or something.
He should generally be neutral ingame, but go into "bad time mode" when any UT related monster in the mod dies in a 20 block radius. (Which is inaccurate to canon, but this IS minecraft).
In terms of additions, I'd consider playing the actual UNDERTALE game or going on the actual wiki. I'd say it'd be beneficial to add minor enemies like froggits or the canine units, and focus on adding content from the ruins to snowdin. (Maybe even with a snowdin structure in the ice spikes biome or just have the mobs spawn in a structure based on their respective locations?)
Canonization and new mobs aside, the only other thing i'd suggest would be craftable food items that heal you when consumed. (Based off the game, obviously.)
