I don't think Wonder Woman ever encountered Vartox and yet I feel like he would make a phenomenal antagonist/ counterpart to her. His powers are about astral projection and psyonic abilities, a sort of new age superhero, which fits very well with how Marston had Diana and the amazons use telepathy in conjunction with their technology, and the secret martial arts they invented.
I'm not really interested in the chauvinistic harasser who can't stop throwing himself at women, but more with the original version whose wife died because unbeknownst to her she had always been psychically linked to a human woman and when that woman was killed, his wife also became brain dead. He was a honorable spiritual dude from a world that searched for ways to transcend the physical plane.
