Having finished a series of redesigns for the Justice League and their nemeses the Injustice League, I decided to do up a few redesigns of some of the Green Lantern ladies I'd intend to utilize within the series. The first is Katma Tui.
Borrowing elements from her narrative with John Stewart, Katma Tui's story in this re-envisioning of the DC Universe would see her acting as Hal's mentor and later as his lover. Katma Tui would be characterized by her no-non-sense approach to ring-slinging and by her by-the-books personality. It's clear that she desires to be the best Green Lantern there ever was and she works even harder to be such once Sinestro defects from the Corps. When Sinestro betrays the Corps, suspicion falls on Katma and many question her loyalty. She is assigned the sector Earth occupies as a supposed punishment and becomes the partner of the mouthy Hal Jordan. Though the Guardians view this arrangement as a trial for Katma, she comes to love Earth and Hal. In many ways, I can imagine her dynamic with Hal being akin to that of Olivia Benson and Elliott Stabler on "Law & Order: Special Victims Unit." Hal is brash and aggressive, often acting before he thinks while Katma is more thoughtful and caring but is still able to keep up with the boys. Of course, once Hal and Katma give into the sexual tension that permeates their partnership this signals the end of Hal's relationship with Carol Ferris. Unfortunately, any hope that Hal had of forging a romance with Katma is ripped away from him when the Guardians decide that Katma is ready to be removed from the backwater sector and assign her a more prestigious sector to watch over. This is naturally where John Stewart would come in. He'd be Hal's new partner and would likewise be trained by Katma... further romantic tension ensues and a nasty love triangle too!
Since Katma Tui was killed off in the comics before women started dressing stylishly again, there was very little I had to go on in terms of giving Katma a cute little costume. I took inspiration from her standard costume and used my redesign of Hal as the basis. I created a new look for Katma that blends all elements and really highlights a seriousness and practicality of the character I feel works really well.
Remember, all info here is speculative and is significantly different from canon versions. This is my imagination running wild. Of course, you can see the other redesigns I've done in my gallery too!
