-i

Background
-i was created by Fred to counter i's mischief. Fred, at first, was tired of i's mischief, but could not think of a way to defeat him once and for all. Finally, he came up with a solution. Each day, Fred secretly threw a bit of salt (contaminated with the X-Virus) over his left shoulder, where i usually perched. The next time i popped out to mock Fred again, he got infected. After a week or so, the symptoms were clear. i was unable to talk and could barely flap his bat-like wings. His indigo color had also become a pale lavender. Finally, a month after getting infected, i coughed out the black X-Antibody fluid. However, something unusual happened. The fluid, instead of forming into the X-Antibody, glowed purple, then vanished!

Fred, trying to figure out what happened, was alerted by a second creature perching on his right shoulder. He looked over to see what had happened.

The fluid had evidently summoned -i from the abstract world. -i smiled at Fred, then began helping him out by organizing all his files and folders. Somehow she knew exactly what Fred wanted done.

Then she became Fred's companion, following him everywhere and giving him advice and opinions on daily, routine decisions. Whenever i popped out to try and annoy Fred, -i did her best to keep Fred from losing self-esteem. So far, it's working pretty well.

Description
-i takes the form of a two-inch tall letter "i", in blocky sans serif font, colored light yellow. The tittle of the i is -i's head. Above that is a glowing yellow halo. -i has a set of green butterfly wings, with which she flies. The telltale "X" that shows -i is an X-Antibody is positioned at the top of -i's body, and is colored a deep violet. A minus sign trails -i to her immediate right (which is your left), hovering above the ground.

Trivia

 * -i, like i, has a rather fitting theme song.
 * -i, like i, has no visible eyes. However, she does see using patches of skin sensitive to light that are located around the same place where her eyes should be. Her vision is poor compared to penguins, but superior compared to jellyfish.
