Marvel: the Laughing Bat

My name is Wayne, and I am a time traveler. You can also call me Bruce Wayne, or another name I prefer: The Laughing Bat. At first, I traveled to the DC world and became Batman here. Like Batman in other universes, I have been a knight and righteous all my life. Dark sin has always been with me. I trampled on the corruption and filth of Gotham City and became a hero in this world. But in the end, I still killed the clown out of impulse and was infected with the laughter virus. After that, I inexplicably traveled to the Marvel world, took with me the identity of Batman and the Laughing Virus, and became the young master of the Wayne Group in this world. The only difference is that the Wayne Group here is just a holding subsidiary of Stark Industries. Then, things get interesting. Next, how should I fill this equally decadent world with laughter? Haha... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
