Here's a power I've been thinking of using. Mind you, I'm not even sure I'll have time for this RP but since I was in a previous PITY RP long ago I feel I should keep it in mind.

How do you feel about a character being able to manipulate how perceptible he is to people? Say he could make himself completely imperceptible, where people are completely unaware of him, unable to touch see or sense him in any way. Perhaps even be unable to recall him. On the other extreme he'd be really obvious. People would just sense him even if not looking at him, they'd pay him attention over other people, his voice would drown out that of others. I'm still thinking on the limits and whether this ability also affects machines such as cameras, microphones, and and other recording/detection equipment, but what do you think?
