Powers
Memory erasing: Postman can telepathically reach into another being's cerebral cortex and erase parts of it selectively. He relies on verbal triggers to control the scope of his power. For example, if he says "tonight", his victim will forget everything after the sun went down. If he says "gun", the victim will forget what a gun is and how to use one. Left unrestrained, his power can completely wipe someone's mind, leaving them in a vegetative state.
