Blue Beetle (Jaime Reyes, but I wouldn't mind others).

Green Arrow

^^^I mean I would LOVE a Rogues series, but only Trickster would be weird. He works so well because he is a part of the Rogues. I see what you mean though and I would definetly give it a try. I would also LOVE a series about Captain Boomerang.

A Rogues book would be interesting. If nothing else, at least a miniseries.

I would say Deathstroke but he's getting a new one soon. So I'd say Tim Drake or Cassandra Cain.

Out if these Martian Manhunter? Give one of the most powerful Justice League Member some more respect.

@Elaexy Except Trickster (James) was a solo act for the majority of his New Earth career. All of the Rogues are solo criminals who occasionally work together, based on majority lore. I liked when James worked for the federal government. I’d read a mini about agent Trickster going on missions. That said, it wouldn’t be as goofy of a title as I imagine the OP is picturing.

@N8THGR852 James works as a lead character, but I don't think Axel does. Agent Trickster would have worked. But now what would you do with a James Jesse series. It's not like I am not a fan. James is my favorite Rogue and The Greatest Trick of all time is one of my favorite Flash story arcs and maybe even my favorite one featuring a Rogue. I just think that a Rogues series would work much better than a Trickster solo series.

Well what I have read from Flash (everything from 2010 till now) the Rogues work mostly together. That's part of their strength. Occasionally one or two would miss or a new member comes, but they don't steal a bank solo. It would be dumb anyways.

Sounds like modern writers only know how to group the classics together, huh? Each of them has been such a threat in the past that they’ve put Flash (both Barry and Wally, really) in a run for his money. And then once they’re grouped together, their individual threats are nerfed. “The Rogues” was a marketing gimmick to show the villains altogether. Now it’s an in-universe crutch.

As an aside, I think just about anyone could have a mini written on them. DC has done some wild minis in its history.

I don't think that's a bad thing. Making them a villain group specific to a hero makes them unique.
