Author's note: I don't own those characters.
Judge: Now, begin.
Joker: I was just a normal man who wanted to make people laugh. Until one night, a bad experience changed me. While doing my own errand in a chemical plant, Batman shows up and it's because of him that I got knocked down into a vat of chemicals, turning me into the way I am. This is one bad night for me. It only takes that kind of event to lose my sanity and become the monstrous clown that he sees before him.
Judge: Good. Now, Alchemist, would you share your bad experience that turned you into a monster?
Alchemist: Okay. While I'm with my best friend, Captain Shuggazoom, we traveled to the Netherworld, the home of the Dark Ones. He tried to tell me that it was a bad idea to interact with those beings. How wrong I was. It's all thanks to Mandarin that the machine malfunctioned. Two of the Dark Ones escaped; one went inside me while the other escaped before the Captain tries to stop it. Because of what I had happened, I would become the being everybody would call, Skeleton King. To make sure the universe will be safe from myself, I turned all my weapons into the armor of the Monkey Team. I made them the protectors of Shuggazoom and wipe their memories clean before my time is up.
Judge: It seems you two have quite background stories that made you into the way you are. Now, the winner is... Joker!
Joker: Ha ha ha ha ha ha! I won!
Alchemist: I think your story is a nothing but a lie...
