Saint Seiya
Saint Seiya is about boys in magical armor called saints who run around for the goddess Athena. There's lots of fighting, and even if a character is merely spanked, his/her skin will squirt out half a liter of blood.
They call their armor "Cloths" and generally refuse to refer to them as anything else. Cloths made out of softer metal are the strongest.
Saints fight with an energy called their Cosmo, which is like chi, only better. One's Cosmo is from the power of little tiny solar systems within one's body.
Saint Seiya isn't just popular for it's wacky 80's anime styled bishounen, it's more so for the magical body armor modeled after constellations.
Expensive figurines and model kits are still being made and collected to this day, but what else can you expect from Japanese consumerism?
