Harpie

The Harpies are a special group of female monsters identified by having "Harpie" (ハーピィ) in their Japanese name. "Harpie's Brother" is not a Harpie, since his Japanese name is バードマン (Birdman).

Maximum of 3 Rule
Some Harpies have the phrase This card's name is treated as "Harpie Lady" in their text. Since their name is also treated as "Harpie Lady" while in the player's Deck, a player can only have a combination of 3 cards whose name is treated as "Hapie Lady" in their Deck. "Harpie Queen" is an exception to this rule, since her effect only has her treated as "Harpie Lady" while on the field and in the Graveyard.

Media Appearances
In the anime the "Harpies" are the signature cards of Mai Valentine. She often begins with one "Harpie" card and uses support cards to accessorize and multiply it. Joey Wheeler has also used some Harpie cards as a reminder of his promise to save Mai from the Shadow Realm.

In the Yu-Gi-Oh! GX Tag Force series, Jasmine plays a Harpie Deck.

Structure Deck 8: Lord of the Storm contains an amount of "Harpie Lady" related cards.

Censoring
Most Harpie Ladies in the international release of the game, including all language prints except Japanese, and in the anime have been edited to appear to wear bodysuits while in the Japanese versions they wear much more revealing clothing. "Cyber Harpie Lady" and "Harpie Lady Sisters" have had the spikes extruding from their armor removed due to the suggestiveness.

Play Style
Harpies tend to combine the ability to be rapidly summoned with the ability to destroy the opponent's Spell and Trap cards. They do not have this ability innately, but the field spell card Harpies' Hunting Ground causes one Spell or Trap card to be destroyed every time one is summoned in any way. They are one of the very few cards that can be summoned en masse from the Graveyard. Their support cards, Harpie's Pet Baby Dragon and Harpie's Pet Dragon, rapidly gain in power and usefulness as the Harpies swarm the field. Properly played, Harpies can overwhelm the opponent in moments, but they are individually quite weak, so they are vulnerable to opponents who summon strong single monsters early to whittle down the number of Harpies on the field.
