Card Trivia:Black Metal Dragon
- This monster can be considered the modern "Metalmorph" for the "Red-Eyes" archetype.
- This card can also be considered the real-life version of Dragon Nails due to the 600 ATK boost it grants.
- This monster appears in the artwork of "Return of the Red-Eyes", during the process in which it fuses with "Red-Eyes Black Flare Dragon" to become "Red-Eyes Flare Metal Dragon".
- If this card is equipped to "Red-Eyes Black Dragon", its ATK becomes 3000, the same as its rival monster, "Blue-Eyes White Dragon".
- True to the fact that this card is a "Red-Eyes" support card without "Red-Eyes" in its name, this monster appears to either have white eyes or no eyes at all.
