Gemini's asleep, but I can answer your questions since I'm crazy enough to be up at 3 in the morning. I know alot about her physical decription from real life and her detailed RPs. And she'll correct me if i'm wrong, tommorow.
Gemini alternates between ponytails and free flowing.
STOP CALLING IT BATTLE-GRADE FEETY PYJAMAS! It takes all the respect out of it! this is an elite battle-suit, offering maximum durability and flexibility! Yeah, it's dark green and the metal's bluish. Actually more of a Cyan. Finely woven, so a haze of thin lines will work.
Gemini wears several different clothing combinations. Her brown T-shirt when she wants extra maneuverability has blue stripes...uh...on the shoulders, I think. Then there's her bulky steel platemail armor. And then there's her 2-piece when fighting in a desert environment. Oh god...never fight Gemini in a desert. Ever.
My zodiac sign's Aquarius. Thought you knew that already?
Matt, I like you...r art skills and personality. no homo.
R2D2: That's not her own blood...it's the blood of countless enemies, engrained into the hammer, corrupting it, poisoning it. Once, in an RP on a Chatzy, she sledged me right in the arm. Tore it straight off. I got hepatitis in the RP. That's how poisonous the blood-soaked hammer is.
