It’s not Green Arrow. They said it won’t be a hero they’ve already reintroduced (last year, they “rebooted” their entire continuity, and are still rolling out some of their, erm, retooled characters).
They said one candidate is a character called Vibe. Never heard of him, but the name sounds appropriate.
Vibe the “hip” hispanic character that went nowhere?
The one who whose power was vibration? (human vibrator?)
Warner Big boys should be firing the lot at DC.
