Throughout this series, we've seen quite an interesting array of fashion senses displayed by various heroes, from the typical to the honestly quite cool to the frankly bizarre. I'll let you decide where the Blue Lady falls.
Lucille Martin was just your average novelist who, on a return trip, is gifted a magic Bird Ring. Later, after some other incidents, she discovers she has unlocked super strength and, after a couple of issues, she discovers she can evaporate into mist! Y'know, like birds.
Deciding to put her Bird Ring powers to good use, she takes up the moniker of "The Blue Lady" and makes her own costume... complete with a bird hat for some reason.
Unfortunately, she only lasted for 3 issues.
