Pandemonium Monster

A Pandemonium Monster (Japanese: パンデモニウム Pandemoniumu Monsutā, abbreviated モンスター in ) is a type of created by Meedogh. A Pandemonium Monster can be from the  to your  as a ; once flipped face-up, the player can also perform a Pandemonium Summon.

Pandemonium Monsters can also be Effect, Ritual, Fusion, Synchro, and Xyz Monsters, as well as Tuners.

Characteristics
Pandemonium Monsters are visually reminiscent of, with the difference being that the green is exchanged for purple, drawing a visual link to their Trap-like function.

Pandemonium Monster can be used in two ways: Summoning them as monsters, or setting them in your Spell & Trap Zone as Trap Cards. Similar to Trap Cards, they cannot be activated the same turn they are Set, but can be activated in any phase of either player's turn, and can be activated in response to other Spell Speed 1 or 2 cards and effects.

While not in a Pandemonium Zone, they are treated as Monster Cards, and they apply their, but not their Pandemonium Effects. They can be by appropriate card effects, and if it is a  or, it can be Normal Summoned from the hand like any other Normal or Effect Monster.

Pandemonium Zone and Pandemonium Effect
While in the Pandemonium Zone, they are treated as Trap Cards, and apply their Pandemonium Effects, but not their monster effects. The Pandemonium Zone does not naturally exist until a Pandemonium Monster is either flipped face-up in the Spell & Trap Zone or placed face-up directly into the Spell & Trap Zone, at which point one will be created underneath it. That zone will be then on considered a Pandemonium Zone, and will remain one until the Pandemonium Monster moves to a different location.

Upon resolving, Pandemonium Monsters remain face-up in the Pandemonium Zone as a Trap Card, and it gains its Pandemonium Effects, if any. Despite being treated as a Trap Card while in the Pandemonium Zone, they are not considered, , or.

Pandemonium Summon
Once per turn, during the, while there is a face-up Pandemonium Monster in the Pandemonium Zone, the turn player can perform a Pandemonium Summon using the Pandemonium Scales on the Pandemonium Monster to determine the Levels of the monsters that can be summoned.

Pandemonium Summons cannot be performed on the same turn as a, and vice-versa.

Sent face-up to the Extra Deck
If a Pandemonium Monster would be sent from the to the  (either as a Monster Card or Trap Card, and even if it is face-down), it is instead placed face-up in the. If they would be sent to the GY from any other location, such as the hand or Deck, or if detached from an, or if its effect or activation as a Trap Card or Summon were negated, it is sent to the Graveyard as normal instead.

A Pandemonium Monster that is face-up in the Extra Deck can be Pandemonium Summoned in addition to monsters in the hand, granted that its Level is between the Scales of the Pandemonium Monster used to perform the Pandemonium Summon. However, these monsters can only be Pandemonium Summoned to either a that a  point to, or an  if unoccupied.

Pandemonium Monsters cannot be used to pay costs that would send cards from the field to the Graveyard, as they do not end up in the Graveyard when a player tries to send them there. However, this does not stop them from being as cost, as they will still be able to enter the Extra Deck. If the effect of a card like (which banishes cards that would be sent to the Graveyard) or  (which shuffles monsters destroyed by battle into the Deck) is being applied, the Pandemonium Monster will instead be sent to the location specified by that effect.

Due to Pandemonium Monsters being added to the Extra Deck, they can cause the total amount of cards in the Extra Deck to exceed the limit imposed in Deckbuilding.

Extra Deck Pandemonium Monsters
Monsters that start the Duel in the Extra Deck can also be Pandemonium Monsters, in addition to their other Types. Because they cannot be placed in the Pandemonium Zone via conventional means, they often have an effect that allows them to either be Set in the Spell & Trap Zone or activate as a Pandemonium Zone directly. Pandemonium Monsters that are face-down in the Extra Deck cannot be Pandemonium Summoned, and only once they have been placed into the Extra Deck face-up are they allowed to be Pandemonium Summoned. Consequently, face-up Pandemonium Monsters cannot be Fusion, Synchro, or Xyz Summoned, but can be Pandemonium Summoned.

As they do not have a Level, Pandemonium Xyz Monsters often possess an condition that allows them to be Pandemonium Summoned as long as the player is able to Pandemonium Summon a value specified on the card that is equal to its original.
