Postman, Anaconda, etc
To say that Postman didn't want to be in this situation would have been an understatement. A believer in peace whenever possible, he would have preferred to be doing almost anything other than waging war on a combination of Brotherhood members and ... other people who seemed to for whatever reason be out to get him. There was no way to avoid using his power, making the situation even more uncomfortable; the only blessing was that he'd thus far been able to get away with half measures, even convincing one lizard-man to walk voluntarily into Susan Storm's forcefield in search of answers.
He didn't think it would keep being that easy, though. Not when violence was rising, and the less cerebral fighters were getting caught up in bloodlust and battle fury. As far as combat went he was just a man, and one man, however good shape he was in, had rapidly declining odds in a battle of lazer beams and earthquakes.
