Yeah, but the general populace of Earth has no idea what goes on inside Kandor.
Enh, Lor-Zod's DNA is 100% Kryptonian, soo... Yeah yeah, not born on Krypton, knows little of their culture, but still born A Kryptonian.
But anyways, Lor-Zod actually used the Nightwing identity in places like Metropolis. PG didn't. So The DC universe's in-universe version of the interenet... would only have info on 3 users of the Night Wing Identity... Dick, Cheyenne, and Lor-Zod.
Ok, I forgot that one. Never read that comic, and for some reason thought it was newer than it actually was. ok so... maybe 4. Oh, wait... actually I have. This is the guy Dick hates for using a similar name. He tries to be a vigilante, but mostly just beats up random people. Hmmm Enh, He'd probably get hits.. as being a fake Nightwing.
Batman villains are more interesting than Bruce Wayne
Damien outlived his usefulness and is not a really interesting character. If Morrison had just let it go DC as a whole would be in a better place, but because of this one character they were prevented from rebooted the entire DCU from the ground up for New 52. I never found him that interesting, he was like a male child version of Emma Frost who just said "Father!" and "Pennyworth!" all the time instead of having a real personality.
He has way too many Bat-family members that it dilutes the entire point of the brand and makes him look like a ridiculous dick for moping around. We don't need half of them, we don't need any of them. Robin serves somewhat of a purpose since it's tradition but I would honestly just pare it down to Nightwing and maybe Batgirl, and have Bats go solo most of the time.
It does, as there is a limited number of books / plots / spotlight available for the batfamily, and there is always a competition regarding who gets the limited spotlight.
Moreover, as new characters are added, it's common that their writers try to show how cool they are by comparing them to existing characters and diminishing existing characters (Harper compared to the Robins is just one example). It doesn't usually help either the new character or the existing ones when those things happen.
Also, take into consideration that the batfamily all share similar traits and skillsets, and it's becoming ridiculous to come up with a reason as to why only X could do something when there's literally a horde of other bat characters that could do similar things. It's especially true for the less experienced ones.
There's a reason so many people feel that the batfamily is way overcrowded. Even though the batfamily is getting tons of attention right now, still most characters appear only sporadically and most don't have a solo or a team book. Even batfamily events now don't include the entire batfamily, and instead focus only on some (fear state / shadows of the bats are just two examples). There are just too many to include them all.
Part of the wierdity is actually because the Bat-gadgets(like proper batarangs, and those fancy bat-grapples) are super expensive, and thus the Bat-family are actually getting stuff from Bruce in order to be able to use the tools. Sure... you don't SEE Bruce on the book cover, but..... in-universe he's still helping them.
Again, there are two problems -
First, that somehow including new characters leads to them taking traits from existing characters or making existing ones seem incompetent. And it happens all the time.
For exmple, does Ghost maker really need to be better with computers than Oracle?
And then there's the problem of creating new characters when so many existing ones are in limbo most of the time or have nothing to do.
Right now the batfamily outgrew the number of characters it can support. Babs became Oracle again not because of character growth this time, but just to give the spotlight to Cass and Steph.
Huntress and Batwoman are investigating the Arkham tower when Tim has absolutely nothing to do and it's not clear why he isn't one of the detectives investegating it.
And the list goes on and on.
