I'm sure Bendis will create new members too. Between the 2 part millennium event chronicling the the DCU over 1,000 years, making Superman son part of the team, and being the guy to revive them in the first place, I think he's already aiming to make his mark just fine. Clark's time with the Legion is also something that's highly debated within the fandom. You have large sections of the fandom who have no interest in it, and would rather Clark were never Superboy to begin with because they grew up with the 86 reboot.
In my experience, it's only really around these parts with a few of us that you'll hear that it *needs* to be Clark.
If I had to guess, it was likely something dealing with how the Legion as a concept in this day and age can mean so much. They function as an expression of a melting pot of different races, genders, ethnicity, sexual orientation, world views, and worlds all coming together under the unified idea of "lets make things better." As you can imagine, this is incredibly important right now. It would be coming from a writer with a genuine reverence and passion for the classic work of his childhood, but also with with a real passion for shining a light on the world outside our windows. Jon's side of the equation is still unfolding, but I have to imagine part of the idea is to set the youngest up-and-coming Superman character (aka "the future of the family") against this very modern backdrop, and navigate the myth through that filter. Like a souped up version of the ideas present in Miles or Peter's stories in the more modern/current (with the level of freedom afforded there) Ultimate universe.Anyways, what do guys think was Bendis's pitch for the legion was?
But obviously, I'm not Bendis, and I don't even have the stories in question to pull from. I just have interviews and opinions, so my assessment is largely moot lol
