This is a crossover with multiple crossovers. I started a fic like this a few years ago but it was abandoned and got deleted, so I decided to try and write it again with new characters. There will be character deaths and unsettling themes hence the M rating, but I hope you enjoy the story and hope to finish it.

Prologue

Ever since The Joker became president of the United States of America, a new TV show was created for the president's sole entertainment. It was called The Game Of Mass Destruction, and it was a game show that lived true to its title. There have been thousands of petitions to end the ghastly show. Most petitions had been sponsored by the RHF Corp. Nearly all the campaigns were in vain as the show had generous sponsors from all over the world.

The robots were ready for the new series: all two thousand of them. They were ready to destroy any human that dared to meet their eye. Last year's season of the infamous Game of Mass Destruction saw Mitzi Hunt and Susan Ashworth become the only living things left on the island. The rest of the contestants left the island in caskets... except for one man, whose body couldn't be recovered.

His death could not be verified because there was no corpse to verify. First Lady, Harley Quinn was sure he was dead. She would be presenting the show again. She grinned at the list of contestants and flipped through all their profile pages. "This is going to be the best Game Of Mass Destruction ever!" she cackled as she clapped her hands. "I'm so glad Mitzi and Susan have signed up again. I just love their style."

She grabbed her glass of tequila from the table and laid back on the coach. She felt like a kid in the candy shop as she browsed through the profiles of the forty contestants nominated to take part. Some do volunteer, but the majority of them are nominated. When she saw the profile of Hannah Wright, Harley Quinn's smile deepened. "Oh Hannah, I remember your husband. He was a great contestant. Shame he fell down at the last hurdle."

Game Of Mass Destruction was in its eighth series. In her office were framed portraits of the previous seven winning pairs. She had already put a blank photo frame for this year's winner. It could be any pair.

First season's winning couple, Yoshiki Kishinuma and Ayumi Shinozaki had not long had their first child. She was sure that they were celebrating their wedding anniversary as well. Harley frowned, flicking the glass frame holding the picture of Ayumi and Yoshiki. "I wish you invited me to your wedding."

Kai Hiwatari and Takao Kinomiya, two of the greatest beybladers in the world had won the second series. The second season was the first and only time where there were no human casualties. "Still waiting for you two to teach me how to Beyblade."

The clear winner for season three was Bulma and Gohan. The others had no chance with their powers. The survivors were fortunate indeed. Harley continued talking to the winners' photos as if they were still in the room. "If only you could come back and kick some robotic ass."

She stroked the fourth season winners' photo. "Oh, our beloved NaLu. You two had amazing chemistry." She remembered her friend, Poison Ivy won loads at the bookies for betting on Natsu Dragneel and Lucy Heartfilia to win. "I hope you both message me sometime. Would love to hang out with you."

Agent Meryl Strife and the legendary Vash the Stampede won the fifth season. "You were always my favourite in season five," she said to the picture. "You both deserved to win. Even though your sex was awkward to watch. You were both amazing on the battlefield."

Sixth season's winners were Noriko Nakagawa and Shuya Nanahara, the infamous Battle Royale couple. "Oh you two, I wonder what you two are up to at the moment?"

She looked back on the picture of Susan and Mitzi, lucky season seven's winners. "I wonder if you will win the second time around."

"Harley Quinn," the director yelled. "The contestants are ready."

She finished her glass and crunched on the ice cubes. "Let the game begin."
