I turn myself to this community in hope that you could help me find this old anime I am looking for almost 1.5 decade now.

I watched it on the a French channel called "Mangas". The anime itself probably dating between year 2000 and 1980.

The anime had similar points with Saint Seya, namely the team of heroes would wear or more like transform into robots / armored fighter. There were quite around a dozen characters each with a specific transformation, among which one had a "parrot" like armor with green and orange "feather like scales".

The most important clue I can remember is that all those transforming characters had an eye "tatoo" on their forearm ( right forearm I think, usually covered up in bandages ) which would open as the character was say something along the lines of "By the power of the eye (??!) ..." ("Par le pouvoir de l'oeil in the French version ) or something like that.

Hope you could help me find it so I can die in peace when the time comes.

Thanks you for your time. I'll be sticking around.
