Where are the Fishnets?
the breakdown they give for the supposed “Batwoman” char sounds more like Cassandra Cain(orphan)
fierce fighter despite “a small stature.” Angeline is experienced in stealth and able to “wipe out buildings filled with foes all by herself before she is gone like a ghost.”
In Detective, I never got the idea that Kate was big on stealth. but I believe that, while soldiers can be stealthy, a popular impressions of soldiers is more like Cable (lots of gear and big guns) than Shang Chi ( i know I am mixing universes) and Kate is definitely a Soldier in the comics. but the Arrowverse could change that take on Kate.
In the End, I think the main reason they want to use Batwoman is to introduce another lesbian into the show. that is my cynical take on this.
