Born of the soul of an ancient engineer whose name has been lost to the ages, Kaiser Zeta carries the eternal hopes and dreams of youth in his robotic shell. He has burst forth from the spirit realm intent on teaching people the power of truth, justice, teamwork, and striking incredible action poses. As a mechanical construct, Kaiser Zeta's alloyed body grants him strong defense, and he can spread a protective field over allies, reducing the damage they take. His greatest technique, however, is combining with an Envoy like a suit of armor to battle with blazing passion.
Kaiser Zeta is based on Icarus, the son of the master craftsman Daedalus in Greek mythology. Often depicted in art, Icarus and his father attempt to escape from Crete by means of wings that his father constructed from feathers and wax. Icarus' father warns him first of complacency and then of hubris, asking that he fly neither too low nor too high, so the sea's dampness would not clog his wings or the sun's heat melt them. Icarus ignored his father's instructions not to fly too close to the sun; when the wax in his wings melted he tumbled out of the sky and fell into the sea where he drowned.
'Kaiser' is the German word for "emperor" whereas 'Zeta' is the sixth letter of the Greek alphabet.
