Pandion II was the son of King Cecrops I of Athens. He succeeded his cousin Metion as king. Metion himself had previously exiled Cecrops and taken power, being the son of King Erectheus. Pandion II was later exiled by Metion's sons, but was restored by his sons; Aegeus, Lycus and Nisos. Pandion was succeeded by Aegeus, while Lycus ruled over Lycia and Nisos over Megara.
