Personally, battling Sans was a highlight for me! Complete the Genocide route and you’ll find him waiting in the Last Corridor for an epic showdown.
Just finish the Genocide route and Sans is your final boss. Be prepared for a tough fight. Good luck!
You can fight Sans by completing the Genocide route. Basically, you gotta be a total savage and eliminate all the monsters in the Underground. Sans will be waiting for you at the end in Snowdin.
