The enderdragon is a divine beast that's power is not matched by any other force. But there is a way to kill the dragon. The easiest way to do it is to kill several endermen on the ground of The End. You then collect the enderpearls that they dropped and shoot yourself up to the top of the healing towers. You use a bow and arrow, or snowballs, and shoot out the healing crystals around you. Then, when your heal is back up, shoot yourself to another tower or to the ground and repeat this system. Once you have done that, you have to actually fight the Enderdragon... Now many people believe that this is a difficult task but as long as you have a good strategy it will be quite easy. In your inventory have your items like this: Slot #1 Bow. Slot #2 Diamond Sword. Slot #3 Fishing Rod. Slot #4 Golden Apples. Slot #5 Snowballs. Slot #6 Arrows. Slot #7 Arrows. Use your bow to shoot the enderdragon when he is far away and when we comes at you, hit him with the sword. If he is close, but not close enough, catch him with the rod. If you need food eat the apples. If he is low on health throw snowballs. When you are actually fighting him, make sure you are on an Obsidian Pillar so you don't get attacked by endermen. This technique works, i promise. If you like my technique, give a diamond. :D
