Nothingness

The Nothingness archetype is a series of cards that share the following effect:

● "This card's effect is not negated by "World of Vanity and Nothingness". This card is treated as a Normal Monster. This card's Attribute is not treated as DARK while it is on the field. You must discard a card on your hand when this card is "Special Summoned". This card isn't treated as a (Insert Type here)-Type monster while in the field."

All of the Nothingness monsters are counterparts of existing cards, except for "Fiendish Horror of Nothingness"

The Nothingness monsters were somewhat based both on the Nobodies from Kingdom Hearts and on the archetype.
