In the original Japanese version, the agents were all named after phases of the moon, which also appeared on their helmets: Gekkō (‘Moonlight’), Tsukikage (‘Moon Shadow’), Tsukinowa (‘Moon Ring’), Meietsu (‘Shining Moon’), Natsuki (‘harvest moon’), Mikazuki (‘Crescent Moon’) and Getsumei (‘Moon Light’).
The Phantom Agents were modern day ninjas whose enemies were an organisation called “Black Flag”.
They wore old style motorcycle helmets and ran everywhere in single file, but later graduated to a Toyota Crown Saloon.
The Phantom Agents were armed with ninja weapons such as star knives and used guns “only as a last resort”.
Like ninjas they could jump great distances, usually backwards because that’s what happened when you ran the cameras in reverse.
But the thing I remember most was their ability to blend into the architecture, holding a sheet of cloth that allowed them to blend into a wall.
