Sans is back sans is a lazy skeleton that likes ketchup and likes making bad puns about skeletons he may seem very nice at first but if you kill you brother you will have a BAD TIME ahem sorry anyway sans has a array of gaster blasters and can throw bones and is the only one that can save the timeline he can dodge attacks at the speed of sound but the weakness he gets tired as the battles goes on until he is too tired to fight until he falls asleep now unto error sans error sans is a glitched version of sans that thinks everything is a glitch if he thinks your a glitch he will get rid of the glitch himself he can error your soul and control your soul forever and can control you like a puppet in my opion i think sans will win.
