Does wonder woman have siblings

Answer 1

No, and she has never been married which would void her (warranty) as an Amazon. However, she is in a sense the foster Mother of the character Donna Troy who serves as Wonder Girl in the Teen Titans and has the same basic powers as Wonder Woman, this replaced the rather dubious plot device of Wonder Girl being Wonder Woman as a teen-ager- akin to Superboy which just didn"t work out right. Wonder Girl as Donna Troy ( sounds mixed Italian and Greek) a much more plausible gig.

Answer 2

Yes, and of all things she was/is a Black Girl. Nubia the Girl Knight of North Africa figures in a number of Wonder Woman tales and once in Supergirl- how, if they were blood sisters, she is Negro while Wonder Woman is White is not explained. also the Crusader-type get-up would get very hot in North Africa, perhaps this is insulated and may have muscle-amplifiers. She , while something of a menacing character, is drawn as very attractive. It is a pity they did not develop the character further into a regular and one would hope, Good-Gal Amazon Knight! Mego made a doll based on Nubia with her Armor, breastplate and culottes, and sword and shield.
