Holon

Delta Species and Holon's Pokémon: two different ideas

Pokémon changed by the tower became δ Delta Species, printed with a type other than their usual one (Rayquaza δ, for example, is Lightning and Metal rather than Colorless). A δ card has a coiled pattern around its artwork border and a δ symbol in place of the usual evolution marker. Delta Species ran from EX Delta Species through EX Dragon Frontiers, with a few more on POP Series 4 and 5 and Japanese promos.

Holon's Pokémon are a separate discovery from the same research: Pokémon that can transform into Energy, so on cards they can be attached to another Pokémon as a Special Energy. None of them carry the δ mark. Studying both groups, the story's scientists created the synthetic Holon Energy cards FF, GL and WP.

Holon on cards: five Holon's Pokémon across two sets

Our catalog lists five Holon's cards. EX Delta Species (October 31, 2005) introduced four: Holon's Electrode (Rare, Hisao Nakamura), Holon's Magneton (Rare, Katsura Tabata), Holon's Magnemite (Common, also Tabata) and Holon's Voltorb (Common, Takao Unno). Magneton and Electrode are Stage 1 cards that evolve from the Holon's Magnemite and Holon's Voltorb printings. EX Holon Phantoms (May 3, 2006) added the last one, Holon's Castform, an Uncommon illustrated by Mitsuhiro Arita whose Delta Draw attack draws up to one card for each δ Pokémon its owner has in play.

The village's name also sits on many Trainer cards from the era, including the Supporters Holon Researcher, Holon Scientist, Holon Mentor and Holon Farmer and the Stadiums Holon Research Tower, Holon Ruins and Holon Lake. They depict Holon's people and places, but they are not Holon's Pokémon. For collectors, the five Holon's cards form a small, closed group from the EX-era Holon story, which ran from EX Delta Species to EX Dragon Frontiers.
