I have always been a fan of Mazinger Z and now also with the series of Mazinkaiser... With the new SKL OVAs and the alternate infernal redesign of the robot I thought of creating my own Mazinkaiser.
The idea behind this robot is to make him a force of nature, similar in some way to Godzilla created to fight ( or punish ) those who harm the planet.
So I named him "Mazinkaiser Gaia" or simply "Kaiser Gaia" or "Kaiser-G" in reference of the famous theory to hint that he is the representation of the will of the planet. He has some elements from Godzilla so it's related in some way to dragons, monsters and also to fire or volcanoes in general.
The giant sword that he has would be formed by three scaly whip-like appendages that unite to form the weapon.
