Petra does not often allow herself to be seen at sea, instead drifting within the water along with the other sea life. On the rare occasion a human is able to spot her, she gives a peace-granting smile. No matter what villainy may lurk in their heart, her smile can cleanse it whole and allow them to live a just, honest life.
See Aqua Sphere Petra.
