Dora

Dora is the original home planet of the Dragonia Kingdom. It was destroyed prior to the events of God Mazinger.

History
Dora was once a world teeming with life and housed an advanced civilization. However, for some untold reason a war broke out and with the Megalo Legion causing so much destruction, the planet was left uninhabitable. After the war, the surviving inhabitants took a starship and traveled the cosmos for a new place to live. Upon coming to Earth, they settled on the edge of a continent called Mu, from that point onward events occurred leading to the creation of the Kingdom.
