Card Trivia:Urubonus, the Avatar of Malice
- This card's name is based on the uroborus (an alternative spelling of ouroboros), a symbol of a snake eating its own tail, representing infinity.
- This card's OCG/TCG artwork is taken from Yu-Gi-Oh! GX chapter 20: "Let the Tournament Begin!!", specifically from the panel showing this monster being Summoned, albeit with slight changes to the pose.
