A/N –I do not own Alex Rider or Batman and please put a review!
Ch4-Alex to the rescue
Alex knew that there was only seconds left until everybody in the whole world would transform into the crazy Joker. He looked around for something to untie himself and Sabina with and found a sharp knife next to him. Quickly, he grabbed the knife and began cutting at the ropes frantically as fast as he could. Once he had freed Sabina, Batman and himself, he said to Sabina "Hurry and find an antidote to this crazy disease so we can cure Batman and while you do that I will find a way to disarm the bomb. Sabina nodded and began searching for a cure while Alex frantically searched for some way to defuse the beastly bomb. Meanwhile around the world, people were reacting to the disease by their faces turning white and they began to laugh maniacally knowing that somebody who would defuse the bomb will be their only hope. Back at the Joker's lair, Sabina had triumphantly found a vial labeled "In case this plan will not work". She hurried over to Alex who was still searching for a way to defuse the bomb and handed over the vital antidote. Alex ran over to Batman and said "I just hope this works" and stabbed the antidote in Batman's arm. The Caped Crusader began to heal in matter of seconds and quickly got up. He had a special remote control in his hand and pressed the UN-detonate button. Suddenly an alarm rang in the Joker control panel and Joker and the Jester came running over. Batman and Alex had just saved the world from the hands of the villainous Joker. All across the world, the effects of the Venom disease were fading and they realized that someone had saved them. The world began cheering for Batman and his new sidekicks. However in the Joker lair, Joker began to wail whilst saying "Do you know what you have just done". Alex replied "Yes we saved the world for a fatal disease and stopped you from becoming the King of the world". Joker suddenly rushed at Batman but he dodged. The fight had begun.
Stay tuned for the big fight! And remember I won't be writing until I get my reviews for this story
