I have been looking for an anime for about 15 years. I originally watched it on a French channel called "[Mangas][1]". the anime itself probably dates from between 1980-2000.

The anime had similar points with Saint Seya, namely that a team of heroes would wear (or more like transform) into robots / armored fighter. There were around a dozen characters each with a specific transformation, among which one had 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 tattoo 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).
