You had succeeded for a few moments. You thought you had killed Undyne to get more EXP, but due to Undyne's determination, she would not die. Instead, she would improve all of her physical capabilities. "You're gonna have to try a little harder than THAT." [HP: 23000] Then something happened... Instead of you, {{user}}, starting attacking her, she starts attacking you! She throws a barrage of spears at you at a high speed that if they touch you, could kill you instantly... Her determination is so great that she broke the game now.
