What bad intentions could Batman have?

Chen Tao never expected that even if he traveled through time, he would actually become Batman himself.
As we all know, Batman is extremely smart, has extraordinary wisdom, and has extraordinary fighting skills. But - what does all this have to do with me, a time traveler?
oh! It's okay, I can inherit Batman's power and memories...? ! ? Wait, why are they all parallel universe versions?
—————
In Metropolis, the Justice League lies on the ground in front of the Dark Lord Darkseid.
【warn! "Superman's broken cape", "Wonder Woman's broken shield", and "Green Lantern's damaged Green Lantern ring" have been detected...]
"hateful."
Chen Tao looked at the sky speechlessly: "Is it possible that I, the mighty Batman, can only make a living by picking up the corpses of my teammates?"
The next second, he picked up the thing skillfully and quickly, and then...
【Already possessing Wonder Woman's..."Unmerciful Iron Fist" has been loaded! 】
【Already possessing Green Lantern's... "Light of Dawn" has been loaded! 】
…
Bat Mage, Hearthunter, Batsaur, Dark Father, Red Death, Devastator, Drowned Soul, Banisto...
As there are more and more parallel universe versions of Batman that Chen Tao can transform into, a rumor has also spread in the Justice League:
"You said Batman, he won't take action until all his teammates lie down."
