Looking for an anime where the main protagonist wears a white top and a shorts, has a sword on his back with a red grip and summons a robot or some kind of a suit by using a "COMMA" shaped locket wherein the boy stands on a golden dragon..he has a fat short dark guy as his sidekick who has a mechanical robot too.
I watched this like 7 years back.
