*and Aquaman and Robin, IMO. But lately I wonder if Aquaman would probably be better as "Martian Manhunter-tier" sticking as a permanent Justice Leaguer than a solo series header with how tough it is to freshen old/make up new plots for any solo book of his. I can easily see the five bolded heroes being known for prominent solo and team careers in the public eye in-universe, since they all have home cities and in Wondy's case her very mission involved going to Man's World and living in it, de-facto receiving a supporting cast and rogues' gallery - even a city eventually made for them, Gateway - to keep her in it both pre-AND-post-Crisis. But Aquaman's situation versus Wondy's is too inherently tied to his home realm of Atlantis and I can't see why he'd actively protect, say, New Venice over his kingdom under the sea when most of his solo adventures are set there, and the Justice League logically gives him reason to interact above water. And yes, I know he was raised on land up to whenever he begins his superhero origin and career. Robin for all his immense popularity since 1940 as THE kid superhero is at heart the deuteragonist of the Batman series and a part of that world alongside the true series lead of Teen Titans as a concept. I actually am shocked Dick Grayson - not "Robin", Dick - never became a big deal on his own since he's headlined anthology books and his own series for decades... I suspect it's because he bounces off others much better than a drama-filled solo book, and also not hyping "Nightwing" up enough as "Robin but GROWN UP!" Imagine the world where DC forced the Titans and Bat offices in the 80s to play nice and stress Nightwing as Adult Robin, able to truly function as an equal, in-sync fighting partner to Batman now he's all grown-up without the usual fears on child endangerment and kid soldier BS, yanno? Should've just given him a better-designed Robin costume and keep him that then.
