I was trying to figure out the finer points of Senses, and how one could have directionality in a sense without going all the way to Accurate, which is more expensive and actually pinpoints the subject. Something more generalized would probably be worth 1p, and it occurred to me this already exists: Tracking.
Tracking by Scent is the most intuitive, and Tracking by Sight is the default assumption for the Advantage, but for some reason I can't recall any use of Tracking by Hearing. But I realized that should be what Superman has, even though no build uses this. Most give him Accurate Hearing (and ranks of Extended) for his "patrolling Sense," but by rights Accurate Hearing should be akin to Sonar.
In practice, I think Superman would at best have Tracking Hearing, and then turn his head in the direction of the cry for help. This would likely be followed by him using his X-Ray Vision to pinpoint the distress and fly in.
It's a minor quibble, but I think it fits the concept better, and while not every player is going to want to play Superman, cribbing his powers is fair game.
