I'm just going to power my list with your selections, since we typically agree on so much, ..and I'm too lazy to generate one of my own.
I'll start with the
costumed heroes, most of whom don't even wear a stylized eagle-insignia, who show up for a fight and might generally be associated with the name 'Wonder Woman Family'...
Donna Troy
Artemis
Queen Desira
Nubia
Heroic Perez Hercules
Fury (Helena Cosmatos)
I Ching
Orion of the New Gods
Sargon the Sorcerer
There are regular (every or every other issue), supporting characters, who are also considered members of the family. That would be
Etta, Steve, Mala, Ferdinand and
Queen Hippolyta. Some, like Steve and Ferdinand can easily carry back-of-comic or special story features.
Then, there are less frequently appearing allies, who can be tossed into stories, once in a hunter's moon...
Mister Genie
Andros
Wonder Boy of Viro
A
new team of
Sensation Comics heroes (male and female), who are infrequently recurring allies of Diana
There really isn't a battery of costumed Wonder-people, with cool costumes and codenames, to power a superheroic Wonder Woman family. For that reason, I switched out the obscure, made-for-TV superhero, Andros (a childhood favorite of mine), for Orion, ..simply because Orion is more well-known. It's a little disappointing that there aren't more easily identifiable costumed superheroes, among the ranks of Diana's circle, if only because no writer, since Kanigher, has really seen fit to create any. Of all the above-listed family, only Donna, Artemis and Cassie even carry the W-insignia, compared to the gaggle of Bat-folk, who carry the iconic 'bat'.
Seriously, folks...when the fated call goes out for the Wonder Family, there should be a throng of costumed, super-powered heroes showing up, as BIG, stylish and awesome, as Batman's or Superman's. Where's Wonder Woman's answer to Steel, Batwoman, bla'bla and so-n'so? Where
are they?
