Frisk is a helpful, kind and caring person who wants to bring out the best in others but they are determined to find their Sans. They don't want to destroy AUs like Error because it is mainly pointless to them so instead they help where they can to save or support others in their time of need. Frisk communicates using sign language and glitched images. Frisk rarely talks and never wants to fight anyone, but they will defend themselves if they have to. (They have Error blaster, blue strings, Etc)
