Let me first clarify that I would never want to see DC comics turn into an exact copy of their tv and movie universes. But it just doesn’t make sense to me that they don’t capitalize on a character’s popularity in other media and grow the character further in their comics. I understand that it’s very hard for a mid level character to sell in a solo comic in the current market. But they could add some of these characters to a team book, give them a mini series, or have them show up during an event. Anything.
Some examples:
Artemis Crock aka Tigress has become a fan favorite on Young Justice, yet she’s had one brief appearance in Lobdell’s New 52 Teen Titans run and she was quickly killed.
Cisco Ramon aka Vibe appears each week on one of the most popular superhero shows on tv, yet he’s been MIA for years. At a time when DC claims that they would like to make their universe more diverse it seems like they’re wasting a Latino superhero who has gotten over with the fans (to use a wrestler term).
Jason Rusch was included on the Injustice 2 roster but has been shelved for a long time. Jefferson Jackson has never actually been Firestorm in the comics.
Heatwave has become a great character on Legends of Tomorrow but is barely used in The Flash comics.
DC doesn’t really have a patriotic themed hero other than Uncle Sam. Commander Steel is a regular on LoT but isn’t used in the comics. He could be their answer to Captain America.
The notoriety of numerous characters is regularly squandered by DC.
