Is the series canon? Is there any recommended books to consider before reading?
What is this “canon” you speak of? Did you have a particular substrata of the Omni-multiverse in mind?
Just wondering if it takes place within the continuity of the DCU.
In i think JLA by Morrison and maybe tv series Justice League Unlimited was the concept that Jonzz assumes many identities.
How he kept all these identities going unless he did them one at a time and then discarded them was never addressed.
