"Shining Sly" and "Shining Rabbit"
"Shining" (シャイニング Shainingu) is an archetype of LIGHT monsters used by Vector while under the guise of Ray Shadows in the Yu-Gi-Oh! ZEXAL anime. Several cards have had the word in their names prior, but the group had no support until ZEXAL.
The early "Shining" monsters tended to be evolved versions of Fusion Monsters, such as "Blue-Eyes Shining Dragon" and "Elemental HERO Shining Flare Wingman". These monsters had no connection thematically, but several of them had ATK-gaining effects based on the Graveyard.
The archetypal "Shining" monsters used by "Ray" were (before the release of "SZW - Fenrir Sword") the only Main Deck members of the archetype and featured a radically different style. These "Shining" monsters had a "two-faced" theme, appearing as fairly benign monsters being controlled or influenced by sinister-looking familiars or shadows. Their appearance is likely to have been based on Ray's duplicitous and manipulative nature. They had little cohesiveness gameplay-wise, but all had effects related to the manipulation of damage.
The Yu-Gi-Oh! ZEXAL manga introduced its own set of "Shining" monsters in the form of the "Number S" sub-archetype, which serves as its counterpart to "Number C." So far, the only "Number S" cards are two evolutions of "Number 39: Utopia"– "Number S39: Utopia ONE" and "Number S39: Utopia the Lightning."
"Shining Abyss", "Shining Friendship" and "Shining Angel" are not part of this archetype as their Japanese names do not contain "シャイニング". For the opposite reason, "Number S" are members, since "S" indeed stands for "Shining" in Japanese.
