"Red-Eyes" (レッドアイズ Reddoaizu) is an archetype of mostly DARK Dragon monsters used most notably by Joey Wheeler in Yu-Gi-Oh! and Atticus Rhodes in Yu-Gi-Oh! GX.
The archetype is based mainly on supporting "Red-Eyes B. Dragon", whose card was created to rival the strength of "Blue-Eyes White Dragon". The first Yu-Gi-Oh! movie stated that while "Blue-Eyes" brings power, "Red-Eyes" brings potential.
