Anime in '90s where the main character transforms into red armor with a magical silver box I can't find my favorite childhood anime that was shown on Cartoon Network back in the '90s. 

The characters looked similar to Dragon Ball's, so it was probably a Japanese Toonami show. The hero is a warrior who has a magical silver box which when opens, some kind of a red armor fits on his arms and legs and gives him super fighting powers.

Also, this wasn't a cyborg show or space related show. Plus, the characters were only humans.

I have searched everywhere possible, copied all titles I found into Google Image trying to find an image that would lead me to the name of the anime for 3 days but no success.

Appreciate your help.
It sounds like Saint Seiya (a.k.a. Knights of the Zodiac in NA).
