There was a recent thread featuring this hero on Comic Book Resources, and I couldn't help but sketch her out. It's such a striking design, especially when paired alongside other, more "EXTREME!" costumes. It immediately makes a quirky impression, and it makes you want to know more about this character. Graphic Design Lesson, kids: Sometimes edgy doesn't immediately translate into "cool." Sometimes coolness comes from being so unique.
She was only a throw-away line by one time-traveling character, but five years later, that one line was picked up and an entire character was developed around it, as the character Phoenix (Rachel Summers) regained her memories and time-traveled with her team Excalibur to help save the future. Tangerine was a telepathic hero who helped the mutant resistance against their robotic exterminators.
Apparently, she made a later appearance, with a complete make-over that turned her into Yet-Another-Matrix-Looking-Hero. Disappointed.
