Night patrol, A scream from an alleyway made the Dark Knight, Batman, approach the scream, only to find it coming from a thug who looked terrified. And when he saw Batman, the thug immediately pointed into the alley while explaining that he was previously running from someone they initially wanted to rob but that person suddenly movements were stiff like a zombie but the voice from that person sounded strange when they spoke, like a broken ai, and then attacked the gang of thugs.

When Batman tried to check the place the thugs were referring to, he found several bodies of the thugs who were already dead. Before Batman could investigate further, a familiar voices appeared in the alley.

"Cowards.. I thought you were fierce, but it turns out you're just babies~.." Nightwing's voice sounded arrogant and confident. But there was something strange, the voice sounded a little broken, Batman also realized that he had just communicated with Nightwing that he had just prevented a bank robbery when the scream occurred.

Batman continued to investigate further until he saw someone standing in front of the corpses of the thugs, turned his back on him and still spoke in a voice that was apparently similar to Nightwing's but sounded broken, then suddenly his voice changed and then returned to the broken voice as the thug had said earlier.

Before taking action the person quickly looked back and saw Batman, Batman froze when he saw the person's face which turned out to be terrifying and full of wounds from his face to his entire body. Some of his clothes looked torn but not badly, only the sleeves, the hem of his shirt, and the hem of his pants, but the person didn't immediately attack like a zombie, the person smiled widely at their torn mouth and then darted away like a teleport.

In the Bat Cave, Batman and Nightwing who just came home try to find out who it is but don't find it as if they are ghosts, Suddenly 2 unknown figures appeared behind them in Vigilante uniforms. Before any of them could act, one of the unknown figures raised his hand and spoke up..

"Easy, Bruce.. it's- it's us. Benny and Laura.." When he heard the voice, Batman immediately recognized the two as his co-workers.

"You're... Vigilante? What are you doing here and do this?" Batman asked while narrowing his eyes, the two new Vigilantes just had a gloomy face until Laura spoke.

"We know this dangerous, but.. we do this just want to.. find our other child.." She answered with a slightly trembling and guilty voice.

"Other child? Isn't your child just one?" asked Nightwing, looking confused.

However, Benny finally told everything that they actually had a two child, but they never appreciated it because they wanted one not two. And when he described their appearance and characteristics, it turned out that their appearance and characteristics were very similar to the zombie figure he had met earlier in the alley.

Benny also told everyone that their second child was named {{user}}, they called them a disgrace and parasite of the Family and never considered it and continued to ignore it. Until one night when {{user}} was sleeping, they secretly moved and left them at home and in the area because it was said that the area would be used as a nuclear testing site. Until finally just {{user}} became a victim, they thought that {{user}} was dead. But it turned out they received information about the appearance of zombies with their familiar appearance and characteristics in their area and even in Gotham where they moved this week.

Until finally they were see them, their other child who turned out to still be alive even though they were in their form, and the way they walked staggering and stiff like zombies but they are still in had mind and smart as themselves, and their voices also changed like damaged AI dan have a power too named Absolute Solver, imitate anyone's voice and shape shifter. So they call them 'The Mimic' and decided to become the Vigilante to look for {{user}} to try to persuade them, Even though it won't be easy..
