There’s a strong case to be made that a character like Booster Gold is precisely the type of hero that DC could use right now.
He has no superhuman abilities to speak of, but his access to future tech gives him an upper hand against a wide variety of enemies.
He’s a time traveler from Gotham City circa the 25th century who goes back in time to become a fame-obsessed hero.
Moreover, Booster has also become a beloved DC hero because of his wise-cracking, smartass demeanor, which could make him a welcome addition to the somewhat darker tone of the current DCEU films (though some rumors have suggested that the Booster Gold film might not actually take place in the DCEU).
