Sanstrocity is an unknown entity that appears in the Undertale AU HELP_Tale. It appears to be a forced fusion of several Sanses from others AUs. It mainly speaks in gibberish made from famous Sans quotes and often speaks in the same hopeless tone canon Sans uses.
Not much is known about it, but it first attacks Frisk for no real reasons. After failing to kill them, Frisk uses the Locket on it. It seemingly causes the World to reset, changing something. It seems to have separated all the SOULs within it, releasing many AUs Sanses.
