Okay so somehow I don't know if Gloriana is really what you had in mind, but you said you wanted a unique AE, and all I could come up with for a grumpy/darker AE was pretty similar to Vanadium and other AEs I've seen, so... Lmk if you want me to do it over, I won't be offended at all :)

Your AE is named Gloriana. She has a conquering, fiery personality and is argumentative, vivid, and direct, like the sun, spreading light and strength everywhere she goes. Occasionally this strength is misdirected, until she realizes more harm than good is being done, in which case she instantly remedies everything. Gloriana enjoys sports, dancing, housework, fighting for a cause, and painting, but dislikes reading, losing anything, and seeing unkindness in others. Full of majesty, a person who will always stand up for what's right, there's really no stopping Gloriana - all you can do is watch and marvel.

Your CAPTCHA is a shapeshifter cat by the name of Turqoise, or Turqi for short, who has enormous green eyes with the sweetest of expressions (something rare in a cat, as you may know), a dainty nose, small paws, and a soft cloud of misty gray fur. Turqi is imaginative and dreamy, loving to curl up under the stars and wonder about the world, but habitually shows a more irritable side, after the manner of most CAPTCHAS, especially if disturbed or if others get too emotional. And Turqi likes cat food, playing, and trying to learn the alphabet, but dislikes being made much of, interruptions to routine, and being ordered around.

Your AE is named Earl. He has short blond hair that always looks slightly messy, big oversized glasses, and a pale complexion (a little like Fred Pellerin, if you've heard of him). Usually dressed sloppily, in sweatpants and an old T-shirt. Earl is kind and protective of others, and can always be counted on to help if you need it, as well as easygoing and tactful. Usually takes on the role of peacemaker - unless he's too absorbed in his hobbies to notice the conflict, which sometimes happens. These hobbies are mainly to do with technological stuff, like computer programming and web design. Earl also enjoys studying (especially science and history), teaching, and making stuff (like crafts and machinery), as well as reading, especially science fiction. Sometimes a bit grave, Earl can take a dislike to people who are very flippant, isn't very flexible to changes of plan/routine, and doesn't always have the best sense of humor. But once he gets to know you, he's sweet and accepting - a friend in both hardship and happiness.
