[DC] I'm Not Batman

What happens when Batman is infected by the Joker virus? If you have watched DC's dark event Metal Nightmare Batman series, you will know that Bruce Wayne will darken and degenerate into the craziest and most terrifying Batman in history - the Laughing Bat. If you have played the official game Arkham Knight produced by DC, you will know that Batman will defeat the Joker personality in the body with the help of Scarecrow and his own will, and usher in the rebirth of Batman in the fall of the knight. But what happens when the Laughing Virus infected Bruce Wayne turns out to be a failure? The original clown virus will retain the infected person's thinking, memory and personality, but will replace the infected person's own ideological core and moral principles with the will of the crazy clown. As for this failed product, it still maintains its original function, but it will replace the infected person's own moral core with the thinking principles of Joseph Kerr. And Joseph Kerr is the original personality of the poor clown who fell into the chemical pool, had a normal family, and had not yet become crazy. This is the story of Bruce Wayne, who lost his memory and had the memory of Joseph Kerr after being infected by the failed Joker virus.
