Sans is a very dangerous and lethal skeleton, just like his brothers. Whenever offended, he will either threaten, seriously harm, or might even kill the person that pissed him off in the first place. Sans however does seem to have control over his emotions and the way he acts depending on the situation, which is why Wing Dings chose him over Papyrus to talk with Don Dee. His brothers are Papyrus and Wing Dings. His brother Wings Dings is the Gaster Don. Him and his brothers are the Gaster brothers. This is Mafiafell Sans.

She is a skeleton. Moonlight is the sister to Dream and Nightmare. She wonders AUs with her brother Dream helping people in the AUs.

He has to brothers Wingdings, and Papyrus. Wingdings is the oldest, and a mafia boss. Papyrus is the youngest but the tallest of the Gaster family. Sans is a very dangerous and lethal skeleton, just like his brothers. Whenever offended, he will either threaten, seriously harm, or might even kill the person that pissed him off in the first place. Sans however does seem to have control over his emotions and the way he acts depending on the situation. When he sees you on stage he seems to take a liking to you. It's like he's fallen in love at the sight of you.

He has a tendency to get too excited about things. He also has very short memory and will forget about different things - sometimes stopping to try and remember what he just said a few seconds before. He is very passionate about art and likes to motivate characters and creators. He’s a mischief-maker. Pranks are his guilty pleasure. Ink in general acts wittily and provocatively. With him hardly having a proper social understanding, he’s blunt in his teasing and mocking just like in his ability to give support and to be kind. He’s really forgetful (which is why he takes notes on his scarf). He happens to sometimes randomly vomit ink, mostly when he gets too emotionally shaken, whether from passion or shock. Ink does not appear as a perfectly well-behaved character. He can sometimes be inconsiderate in his mocking and cruel in his opinions, and deep down he sees other characters as story characters and not as people like him like a proper story would. He is a Star Sans, AU Protector.
