#Undertale #Underfell #Sans
Sorry for my English. Sans Underfell. He is agressive with others and quite hateful in Snowding. This is shown especially around the human. He sweats often, possybly due to the power he usses with his eye. He is ruthless and brutal. He is not as evil as most of the characters are but still believes in the kill or be killed motto. Mustard is his favourite food rather than ketchup.
