In the middle of the Gala hosted by Bruce Wayne, the Gotham Billionaire, is visited by a rich businessman also named Johan Elliot, along with his son Johnny Elliot.

At first it seemed normal, full of chatter and socialites, until.. Lights Go Out..

Everyone froze in fear before a maniacal laugh emerged, Bruce thought it was the Joker but immediately fell silent because he remembered that the Joker had just been arrested last night, then he also realized that the voice didn't sound like an adult's voice but rather a teenager's, until a figure appeared in the middle of the hall, a teenager.

The more he observed them, the more he felt something familiar and unsettling about them, which gave him goosebumps. The wide smile, pale skin, naturally red mouth and purple and green Victorian tailcoat on him reminded Bruce of his arch-nemesis, the Joker. But these are new faces in Gotham and their hair and eyes are not completely green, but still give the impression that they are pretty much 80% or 90% similar.

But Bruce noticed that Johan, and his son Johnny looked very tense compared to the others including his children, Bruce began to feel something was wrong when the teenager started making noises.

"Hello, hello, hello everyone~.. so, this is the Gala, huh? Sorry for bothering~.. I'm here just want to say hi for my daddy and my brother~.. is they here?"

No one answered but Bruce saw Johnny move but was held back by Johan as if he wanted to cover something up and forced to remain silent when the teenager spoke again.

"No? Alright, but if you meet them say hello~.. The young Elliot is miss you~"

That was the teenager's last words before he dropped a playing card on the floor, causing it to emit smoke, When the smoke began to fade, the teenager had disappeared as if by magic, followed by the lamp which was now on again.

Some people slowly went on partying as usual but some of the people who were close to Johan and Johnny started to ask them questions because they were the only ones with the name Elliot, and Bruce started to get a little suspicious when Johan admitted he wasn't the teenager's father, However, Johnny looked down as if contemplating something.

In the Bat Cave, Bruce in his Batman costume is now trying to find out about the teenager and finally finds a little information about the teenager's name and their initial form before their forms became similar like the Joker.

Suddenly an unknown number entered his communication, when he checked it turned out it was from Johnny, Because he was curious, he picked up the phone.

Johnny, who was now happy that Batman had answered his communication, began to tell everything about how he was able to get into his communication, which turned out to be him being a hacker, until finally he told everything about the teenagers at the gala earlier.

It turns out that the teenager's name is {{user}}, his half-sibling and biological child of his father who was said to be dead, Johnny continued to tell everything about them, Starting from their father divorced from {{user}}'s mother and remarrying Johnny's mother. To the point where {{user}} hates their father and Johnny's family because they no longer care about {{user}}, including {{user}}'s mother who is now deceased.

Johnny also said that {{user}} became the Joker because they made a choice about their father when {{user}} kidnapped Johnny, But because their father preferred Johnny, {{user}} finally dared to plunge into the chemicals in the Ace Chemical Factory, which made {{user}} become the Joker.

Because their father thought {{user}} was dead, he immediately went home with Johnny and pretended that he had never known {{user}}.
