The Big Bad Bat
!No moral integrity!
Mark never expected that after transmigrating, he would become none other than Batman himself.
Everyone knows that Batman is incredibly intelligent, possesses exceptional wisdom, and has unparalleled combat skills. But—what does any of that have to do with me, a transmigrator?
Oh! No worries, I can inherit Batman's powers and memories...?! Wait, why are they all from parallel universes?
Metropolis. The Justice League lies defeated before the Dark Lord Darkseid.
[Warning! Detected "Superman's Shattered Cape," "Wonder Woman's Broken Shield," "Green Lantern's Damaged Ring"...]
“Damn it.”
Mark looks up at the sky, speechless: "Am I, the dignified Batman, doomed to survive by scavenging my teammates'... again?"
The next second, he skillfully and swiftly picks up the items, and then...
[Acquired Wonder Woman's... "Merciless Iron Arm" loaded!]
[Acquired Green Lantern's... "Dawn's Trickster Light" loaded!]
...
Batmage, Heart-Hunting Bat, Bat Overlord Dragon, Dark Father, Red Death, Ravager, Drowned Wraith, Bat Mephisto...
As Mark gains the ability to transform into more versions of Batman from parallel universes, a rumor spreads within the Justice League:
"You know Batman, he won't make a move until all his teammates are down."
