Mea is the ruler of the undersea realm of Mermea, inhabited by a people known as the Sea Amazons. That's sort of a double whammy as far as comic book races go!
In one of the adventures of the underwater adventurer Typhon, the hero notices a pack of raiders known as sea demons...
Their target: Mermea! Queen Mea leads her kingdom against the foes, commanding both her troops and the fantastic Guardian of Mermea, which is a pretty awesome monster.
While Queen Mea clearly resides beneath the sea for the most part, she is often found in Dogwood City, being a founding member of the iconic hero team known as the Association with colleagues such as Nature Man, the Black Lion, the Arrow, the Owl, and Margo the Magician. Like the heroes we know as Diana and Orin, most people in the world of Dogwood City probably call her a different name. I don't know that Wonderaquawoman is a good one...so maybe something like the Queen of Tides. Here she is at the PDSH wiki.
