Kakashi in Gotham
Kakashi dies and when he wakes up he is in a different world.
This World has Absolutely No Chakra.
He studies this new world getting all the information he could.
He discovers he is in a City called Gotham, That heros and Villians exist but not Shinobi, that some people have powers And that aliens exist.
The only thing close to Shinobi where a group called the league of assassin but after looking into the group more Kakashi figures out they are nothing like Shinobi Killing just to rule the world.
For some reason he can understand the language the people speak even though he has nwvwr heard of English before.
He uses a Henge to hide his looks.
He has been in this new world for a couple of weeks when he sees a child About to be hit by a car, and before he knows it he is wearing his anbu Mask and is saving the child and stopping the car.
Every time he saves someone he is always wearing his mask on instinct as in a new world he doesn't have an identity.
(Chakra Can't be copied,Can't be learned,Suppressed, So no one except Kakashi should ever have charka)
