It's a female muscle growth story so if you're into this stuff you should stop reading this

Quick recap: Joker made a serum called Titan that cause people to muscle growth (i know

that it makes the body mutate but not in this story). The joker injectad himself the Titan but

Batman defeats him. After a while the Titans loses it's effects.

I do not own any of the following characters

Let's beginn:

„Oh my Puddin!" Harley said looking at the unconscious Joker. She put him into his car and drove to their secret hideout. After two days the joker woke up. „what happened Harley?"He asked. „He defeated you again" she said sadly. „GODDAMMIT!" He shouted slapping Harley. The fair-haired went back into her room.

At that evening Joker started working on the titan again. „ If i put in some more of that and less of that." Joker said to himself as Harley walked at the living room. Suddenly joker had an idea. „If i'd put more radium in it it would make me stronger put also addicted it would be dangerous." Joker said. Harley listened closely.

The next day the Joker knew what to do he has to test the titan on harley. After „Harley could you please come here." Harley was almost instantly infront of the Joker. „Could you please test something for me?" „The Titan?" Harley asked. „excactly" The joker said. „NO! You said it's dangerous." She answered. „No, just do it for me." He said laughing.

„C-c-c-can i think about it. „Sure." He said with a wide grin. As she went to bed she was thinking about the joker. „Maybe he would like me after I tested it and how bad can it be" she tought to herself.

So the next day she agreed to the test. She had to go into a big empty room. „Are you ready" asked the Joker looking trough a window into the room. „Y-y-yes" she answered uncertainly. „3...2...1...NOW" The joker shot the Titan trough a small hole in the window. Harley felt the syringe in her neck.

At first Harley felt nothing but suddenly a huge load of adrenalin in her body. The 5'7" foot tall grew a foot taller. She felt a six pack growing. A huge load of dopamin going trough her body. „ OH MY GOD THIS FEELS SO GOOD" She screamed as her voice got deeper. Her biceps grew quickly. Her A cup grew to a E cup. But after she grew a little bit more it stopped. She was now 7'5" foot tall her dress could barely fit the massive woman. The joker looked with a grin at the most powerful woman in the world. „MOOOOORRRREEEE" she screamed with a deep voice.

She went to the steel door and could easily break it. The joker didn't think she would be that strong. Harley went to Joker's work desk and searched for the Titan. While she was searching the radium fell into the titan. As harley found the titan joker came running into the room. „Harley what are you doing?" screamed the joker. „Shut up" harley said as she injected the titan. This time everything happened faster. A lot of adrenalin and dopamin was pumped int her body. „Yesssssssss" said the muscular woman as her body starting to grow again.

Her six pack grew to a ten pack. Her massive biceps grew even more. Her leggings finally tore apart from her big legs. And so does her dress. Now she was only in her underwear. Her breast grew to an I cup but then it stopped. Harley was 10 foot tall and more muscular than Hulk. Joker looed in disbelieve. All the radium made halreys brain damaged. „Uhhhhhhh" came out of her mouth with a deep voice.

„Harley can you kill batman?" asked the joker. The big woman went out on the street of gotham killing everything on her way. The police called Batman. When Batman saw her he was he was astounished. He tried to fight her but she was just to strong at the end she snapped batmans neck, killing him.
