A New Hero In DC?,

a man reincarnated in the DC universe, in a universe that was destined to disappear, but at the last moment he had another chance.

Author's note:

I don't own any DC comic characters.
I only own my character

English is not my native language, and instead of saying that I know a little, I will say that I use the translator and with some luck it will make sense
