Bronzor has a flat, circular, blue-green body rimmed with six darker bumps. It has two round, yellow eyes and a large bump surrounded by four smaller bumps in its center. A crest resembling an herb or branch is on its back. This crest is said to possess a mysterious power. It was first seen in ancient tombs; objects resembling this Pokémon have been found in tombs as well. Scientists believe Bronzor used to be reflective, and have tried x-raying its body. The x-rays revealed nothing of its structure, however.
Bronzor appears in Pokémon Adventures, in the Diamond & Pearl chapter, as one of Mars's Pokémon. She used it to attack the manager of the Valley Windworks and hold him hostage. When he managed to use his Drifloon to call for help, she tried to have her Zubat bite him in the neck. After growing bored as she always does, she had it use Sandstorm and left with an electricity-generating wind turbine.
In the Pokémon Diamond and Pearl Adventure! manga
Bronzor is one of the Pokémon Byron uses in his Gym battle with Hareta.
If Bronzor is turned upside-down, it will look exactly the same from the front, meaning its front has rotational symmetry. It also has horizontal and vertical reflective symmetry. However, its back sprite only has vertical reflective symmetry.
There is an unused sprite within Pokemon Diamond and Pearl for Bronzor's back sprite which is just a duplicate of its front sprite.
As both of this Pokémon's Abilities are used at the same time in the Pokémon Mystery Dungeon series, Bronzor doesn't have any weaknesses in those games.
