So with her personality, I bet her Legion try-out was even more scarring than usual. Because the Legion didn't tell her why they rejected her!
That's it. That one panel's all she got. That's her fifteen femtoseconds of fame as chronicled in "Adventure Comics", the Legion's companion magazine (a profusely illustrated pamphlet in which the details of that organization's doings are heavily dumbed-down for its dumb, heavy fans). There was no embarrassing flub caught on tape, no near-death accidental misuse of her powers, no anything. Just the Legion's typical "take a belt and beat it" shove-off. The United Planets Freedom of Infotainment Act of 2973, or was it 2979, or 2981? Damn sliding timeline! Anyway, that legislation opened the Legion's bits of business to the general public and it was from those formerly sealed records that I found out why the Legion rejected Rainbow Girl. (And then I blabbed it to her). But it's complicated, so bear with me for a minute. Rainbow Girl can split into four separate energy-beings*, each a different hue. Rainbow Girl Red projects heat rays, Rainbow Girl Yellow projects a blinding light, Rainbow Girl Blue projects a freezing ray, and Rainbow Girl Green projects an enervating ray. Which is not Kryptonite, I hasten to add. But the Legion thought it was and they hustled Rainbow Girl out of their tacky clubhouse in two shakes of a borlat's tail. With no explanation and no chance for her to defend herself. But you know the Legion... they're hell-bent on protecting their own personal Mark McGuire and Marion Jones, a.k.a. a certain Kryptonian pair who are so hopped up on yellow sun radiation they can't even recognize a cool facial hair style when they see it. (I had a sweet-ass goatee and muttonchops and they called me "Pappy Yokum"! HOW DARE THEY. Besides, I've always pictured myself as more the "Earthquake McGoon" type. Only hairier.)
Wait, what were we talking about?
Rainbow Girl! Right! Thank you! So. Rainbow Girl might not have received such a hasty farewell on that fateful day if only she'd opted for a more striking costume. And hairstyle! Here's Rainbow Girl today in an outfit and coif I designed especially for her:
Once Rainbow Girl trusted me enough to take me on as her fashion adviser, I had her toss out every bit of rainbow-patterned apparel in her closet. Which was a lot. Her very noggin emits pulses of rainbow-colored light at all times so I don't think she needs anything else competing with that. Her hair doesn't have a lot of body, so I counseled her to switch to a short, layered spiky 'do which gives it more lift. I also lightened it a bit to bring out her natural purple undertones. (And I thought it looked so bangin' I decided to make my own hair that color!) The costume itself is in a silver-gray metallic fabric with hints of violet and turquoise. The silhouette features a scalloped top to evoke a cloudbank. Rainbow Girl is a helluva fighter both hand-to-hand and in her energy forms, so I designed this as a "working" costume. That means the neckline, while feminine and flattering, is also high enough that her bosoms won't pop out in the middle of a scrap. And there are no high heels or dangling jewelry. It's a business suit, and her business is kicking your ass!
*When I interviewed Rainbow Girl for the job of First Mate I asked her if she could do the work of four people. She said yes, not knowing the four people I meant were Tusker, Plant Lad, Storm Boy, and Weight Wizard.
