A thousand year ago there was a very kind superhero named Batman. Batman tried to save Robin in the middle of the battle between Batman and Joker.
Joker was so strong and smart. He had his secret weapon that could kill Batman. Joker called his armies and fought altogether against Batman.
Robin was also in the fight. Robin was stucked and died because Joker threw a huge rock on him. Batman was not able to save Robin on the hand of Joker.
Since Batman and Robin are good friends, Batman was so mad at Joker because of the death of Robin. Batman chased Joker and killed him with just one punch.
This is the end of the story.
