American comics: What kind of evil intentions could Batman have?

Chen Tao never expected that not only had he transmigrated, but he had also transmigrated into Batman himself.
As everyone knows, Batman is incredibly intelligent, possesses exceptional wisdom, and has unparalleled fighting skills, but—what does all of this have to do with me, a time traveler?

[Green Lantern's "Dawn Lantern" is now installed!]

Bat Wizard, Hearthunter Bat, Bat Tyrant Dragon, Dark Father, Red Reaper, Destroyer, Drowned Soul, Batisto...
As Chen Tao's ability to transform into multiple parallel universe versions of Batman increases, a rumor has begun to circulate within the Justice League:
"You mean Batman? He won't take action until all his teammates are down."
