Baz was only created so that DC could kill off John. When they couldn't do that, they had no plans for Baz. There are too many Green Lanterns. Ship Baz off to the Blue Lanterns. He can be in Kyle's book.
I'm not interested in NuCyborg at all anymore, but I could change my mind if he shared a book with Nightwing, Beastboy, Raven, and Starfire.
Captain Cold could be pretty awesome as long as he's written as morally on both sides, not an anti-hero. Think Bronn on Game of Thrones.
The others are good choices. I'd like to see the Question and Huntress team up again.
Massively disagree with this.
Really? I massively agree with this. Stories just about her and her job were just boring to me. A comic about a reporter by itself would be boring and in the DC world they would have to constantly name drop both heroes and villains that are apart of her investigations to get any readers. "Find out the secret of so and so in the next issue" sort of thing. It can't be because there are not enough female leading comics as it also has to be interesting. Cassandra Cain or Zatanna would be a better option imo.
The Hulk. A puny, super intelligent man risks his life to save a complete stranger from a weapon he himself created and in the process loses everything and becomes the most dangerous being on Earth. Feared by most, he still acts like a hero even when hunted by the government.
This. Completely agree and could not say it better myself.
