Sans by far is the hardest! Undyne the Undying is difficult but with Sans, the fight is longer and very tricky. For Sans you have to remember his moves in order to get pass him. His first attack is enough to explain how difficult he is going to be. Undyne the Undying is hard with no doubt but once you learn the pattern, you will be fine.
