I'd f**king love a JSA series set in the 40's. I'm a big fan of pulp and I feel like we'd get a healthy dose of that in a WWII era JSA.
I gotta agree with dropping the lightning/magnetic powers. It seems like every black man in comics either has a suit of armor or electric powers. Plus, those don't really mesh with the standard "matter copying" abilities of Amazing Men.
I'd totally support AM being able to mimic non-solids (like some versions have done) because otherwise you're largely limiting yourself to "brute" abilities; strength and durability, etc. You could get more variety out of it, copying copper for it's ability to conduct electricity and whatnot, but writers will almost never put that kind of thought into it, it'll just be "he copies a rock, and gets strong and tough."
My kingdom to see Amazing Man get his hands on some Nth metal though.
Agreed. I haven't read DCeased, and have only read a few issues of Injustice, but what I've seen makes it look like Taylor was handed a dog's dinner of a concept and he still managed to make it work. If he can make a flawed premise like Injustice a enjoyable story then he can write whatever the hell he wants as far as I'm concerned.
