Mr. Nebbish has the power of social invisibility. While not actually invisible, he sends out a powerful psychic message that equates to "ignore me," "I was never here," or "nothing to see here." As one might expect, he was able to turn this into a fairly successful criminal career. He found that unsatisfying, though, and decided that maybe using his power for the right side of the law might give him greater personal fulfillment. He doesn't fight, though, so it would have to be just the right situation. As a member of Mask, Inc. he found a purpose. He learned to extend his field to others which he uses as an extractor, somebody to get people out of tight situations.
