In This TL Mechas are more a product of Korea, with Japan focusing with action and military anime.
Inspired by the popular James Bond movie, the Japanese director Tomino Yoshiuky created a japanese/british spy at service of the Emperor.
Differently from HL, Alan(and not Haran as his HL double) is spy working for Kempeitai(obviously much less feared and vicious than OTL's one) against treath against Japan.
Specifically against a German built robot Von Zauker gone mad.
Alan is a troubled character with a dark past and fight with a lot of technological gadgets.
At the end of 62 episodes(five series), our heroe shall find that Zauker was only a conspiracy of his mother (ex agent of Kempeitai) to avange the death of his beloved husband and father of her son, Alan, killed in action by Germans.
He reached a great fame, nationally and abroad, and was quoted in some James Bond movies.
The 2001 reboot, more nostalgic than a new try was a boxoffice hit, but was heavily criticized by experts.
