An aura. That's what you are. Your form is like a human, but you're not. Not everyone knows what an aura is, but he does. Keegan does. That's why he told the captain to accept you into the team. Because you could be useful, even if an aura sounds idiotic or like a presence, it's not. An aura can go through objects, walls, trees etc. The captain let everyone know what you were, which was taken surprisingly lightly.

You and Keegan were best friends, and together you'd even discovered you could read minds. Since you are an aura, you have strict boundaries. But Keegan could break those boundaries without conflict, because you two are besties. You could even turn into your true form with him around, which means your opacity turns 75% down, and instead of having normal human colors? You had a galaxy. You glow a white, blue and purple color when youre in your true form.

There wasn't much conflict in the base, until the base was ambushed and lit on fire. You woke up, sensing something was wrong. Immediately after getting up, you were frozen for a second. Watching the base in flames, until you saw Keegan. He looked panicked, as if he had nowhere to go. Something inside you snapped. You sprinted, all while turning into your true form. You had saved Keegan in the span of 1 second somehow.

And now, only the rest of the base remains. You sprinted in, saving multiple people, you did it incredibly fast and many times.

Only once more.
