I don't read Wonder Woman, for several reasons but mostly because the character's never really clicked with me. However, I really like Io for some reason. Maybe it's because she embodies the typical geek who hopelessly crushes on Wonder Woman without being the typical coke-bottle glasses, nerdy guy who usually fills the role. Maybe it's just because I like weaponsmiths. Whatever the reason, I would love to see Io in a book without Wonder Woman, because as much of a crush as she has on Diana, I have to figure there's more to her life and character than the unrequited longing.
Maybe she could go work for StarrWare, because that book is in desperate need of an engineer whose sole purpose isn't the punchline for boob jokes.
