Disclaimer: I don't own Batman.
Bruce Wayne was at the carnival with Dick Grayson. Bruce looked at all the games and rides. "What's the matter? Remembering your childhood again?" Dick asked. "No. Just I don't really trust these rides." Bruce admitted. "I'll win you a prize to show you how safe everything is!" Dick said and ran over to the bottle game. "How many tries would you like sir?" The man behind the counter said. He was that old carnival type and he was wearing a red and white stripped shirt. "I would like one try!" Dick said in his determined voice. Dick threw the baseball at the metal bottles and every single one of them went flying into the back of the booth. "Whoa son! That's some arm you got there!" The man yelled. "Good job Dick." Bruce said standing next to him. "What prize would you like?" The man asked. A scream was heard from a few booths away. "What's the matter mam? Is Jervis Tetch not the best at mind games that you have ever seen?" The Mad Hatter asked in a raspy voice.
"Dick I think we got trouble!" Bruce said and they ran away. The Mad Hatter ripped the woman's pearl necklace right off from around her neck. "Very nice, very nice indeed!" The Mad Hatter said checking the pearls. "I suggest nobody here try anything funny, because me and my friends will be taking all your money!" The Mad Hatter yelled and people with his mind control tags on their heads walked up behind him. "Not so fast Hatter!" Batman yelled and threw a Batorangs at his hand. "AHH! HOW DARE YOU!" Jervis yelled and his henchmen attacked Batman. "Get ready Robin! There strength is increased by those mind-control devices!" Batman warned.
The first one to attack Robin was a man wearing a motor cycle jacket. "DESTROY BATMAN AND ROBIN!" He yelled. The one that attacked Batman was a woman in a pink dress. "Must do what Mr. Hat says!" She said mindlessly. She whacked Batman with her purse and he went flying. A brick fell out of the purse and landed on the ground with a thud. "Talk about hard headed!" The Mad Hatter said with glee. He snuck around the back of Batman and put a mind-control tag on his cowl. "There we go simple Bat! Now everyone will know where your at!" The Mad Hatter said and laughed. Batman walked over to Robin who was having trouble with both the people with tags on them. Batman grabbed Robin and began to crush his ribs.
"BATMAN STOP! IT'S ME!" Robin yelled in pain. "Batman cannot hear your pleas! He is under my control!" The Mad Hatter said and grabbed a pocket knife. Robin kicked Batman and then threw a Batorang at the Mad Hatter's hand. "OUCH!" Hatter yelled in pain. "Must destroy! Mr. Hat says to." The henchmen said. "I would hate to resort to such a commoners meaning of violence but it seems I that I haven't a choice!" The Mad Hatter said and pulled out a tommy-gun and aimed it at Robin. "Batman is my puppet now!" Hatter yelled. Batman threw a gas bomb at Robin and he was blinded and started to cough. "Get him Batman! I want Gotham City to see how fake their heroes are!" Hatter commanded. Batman grabbed Robin and put a tag behind his ear.
"Destroy Comissioner Gordon! I commandeth thy!" Hatter ordered. Batman and Robin got into someone's car and drove to the police department. "Bullock! The Mad Hatter has attacked the people at the carnival! We need all officers down there now!" Gordon ordered. Batman and Robin appeared behind him. "Batman? How did you know there was trouble? I didn't even turn on the Bat-signal yet!" Gordon asked. Batman picked up Gordon by the neck. "Must kill Gordon for Mr. Hat!" Batman said in a mindless voice. "The Mad Hatter has him under his control!" Gordon yelled. "DROP HIM BATS!" Bullock ordered and pointed a pistol at Batman. The police all took out pistols and aimed them at Batman and Robin. Gordon grabbed a knightstick and knocked Batman over the head with it. Batman grunted and fell back. "Jim? What happened?" Batman asked rubbing his head. Robin punched Gordon into a desk. "Destroy Gordon!" Robin said dryly. "ROBIN NO!" Batman yelled and took off the tag from behind his ear.
"Hatter did this didn't he?" Bullock asked. "Yes. He's at the carnival!" Batman explained. "Alright I'm getting my officers down there now!" Gordon said and picked up the phone. Batman and Robin called the Batmobile to come pick them up and bring them back to the carnival. They arrived at the carnival and it was night time now. The Mad Hatter was standing on a stage. "ATTENTION! We must strike Gotham City when they least expect it!" Hatter yelled to a whole carnival of hypnotized people. Batman threw a Batorang at his hat. "What happened to your plan to attack Gordon?" Robin asked. "I HAVE A NEW PLAN NOW!" Hatter yelled and grabbed his hat back. "GET THEM!" Hatter ordered and all the people chased Batman and Robin. "You distract them and I'll get Hatter!" Batman said and snuck away from Robin.
"Yes soon my plan will be complete! And with Gotham City in flames on it's ruins I will build me a new Wonderland!" Hatter said with glee. "You need help Tetch!" Batman said. "Most certainly indeed...help with my Bat infestation problem!" Mad Hatter said and snapped his fingers. 2 thugs walked up to Batman with tommy-guns. Batman tackled one and knocked him out. "KILL HIM!" Hatter yelled. The other thug turned to Batman but got punched in the jaw before he could shoot. "Now Batman! Can't we talk this over!" Hatter said backing away and sweating. "No!" Batman said and grabbed his hat and crushed it. The mind-control chips shattered to pieces on all the people and they wondered what had happened. "Thanks again Batman." Gordon said and cuffed Jervis Tetch. Bullock made Tetch stand up and walked him into a police car. When Gordon looked back Batman was gone.
