These two cards also represent Paradox himself; "Malefic Paradox Dragon" has the colors of his mask, while this card has his hair color.
This card's art is also a reference to the Paradigm Shift concept itself. Its wings appear upside-down, its feet appear backwards, its tail juts out from its back, and its head almost looks the same upside-down as it is right side up.
This card's Japanese name is redundant, since "シン" (pronounced "Shin") also sounds like one of the words for "Truth". Kazuki Takahashi has stated that the word "Sin, シン" is intended as a pun for "Sin" and "Truth", so this is likely intentional.
