Dialga is a Steel and Dragon type Legendary Pokémon from Pokémon Diamond and Pearl, where it appears on the cover of Diamond. Its Pokédex category is the Temporal Pokémon, and its entries say time began to flow when Dialga was born. In the games' mythology it is one of three Pokémon created by Arceus, alongside Palkia and Giratina, with Dialga representing time. It does not evolve, stands 5.4 meters tall and weighs 683.0 kilograms.
Its ability, Pressure, makes opponents spend extra PP on the moves they use against it, and its hidden ability is Telepathy. Pokémon Legends: Arceus added Origin Forme, which Dialga takes on with the Adamant Crystal; the card game prints that form as Origin Forme Dialga V and VSTAR.
Dialga reached English cards in 2007 as card #1 of the Diamond & Pearl base set, a holo rare, and the Diamond & Pearl era printed it more than any other era in our catalog (13 cards), including LV.X cards in Great Encounters (2008) and Platinum (2009). Triumphant (2010) paired it with Palkia on Palkia & Dialga LEGEND, a Pokémon split across two cards, a top half and a bottom half, that are played together, and Call of Legends (2011) added a holo Dialga illustrated by Ayaka Yoshida.
Dialga-EX followed in Plasma Blast (2013) and Phantom Forces (2014), the latter with a Secret Rare version. Sun & Moon printed two different Dialga-GX cards in 2018, in Ultra Prism and Forbidden Light, each with a rainbow Secret Rare, and then the tag team Arceus & Dialga & Palkia-GX in Cosmic Eclipse (2019). Astral Radiance (2022) introduced Origin Forme Dialga V and VSTAR, with two Secret Rare versions of the VSTAR, and Crown Zenith's Galarian Gallery (2023) gave the VSTAR new art by AKIRA EGAWA.
5ban Graphics holds the most Dialga credits in our catalog (14), with Ayaka Yoshida and Mitsuhiro Arita at four each.
Dialga has had cards in every era since its 2007 debut, from Diamond & Pearl through Mega Evolution. Its special printings follow the game's headline mechanics era by era (LV.X, LEGEND, EX, GX, VSTAR), and the Cosmic Eclipse tag team puts Dialga and Palkia on one card with Arceus, the Pokémon that created them in Sinnoh myth.

The leaders among Dialga cards come from the modern eras, and the most valuable Dialga card is the Secret Rare Dialga EX from Phantom Forces in 2014. All 47 Dialga cards carry a market value, spanning 2007 to 2025, and the ten leading cards hold 79 percent of the total value. Dialga card value sits mostly in a small group of prints, with the remaining cards sharing the rest.
Phantom Forces' Dialga EX leads the most valuable Dialga cards by 1.8 times over the next card, the Ultra Rare Arceus & Dialga & Palkia GX from Cosmic Eclipse in 2019. Third is the Ultra Rare Dialga-EX from Plasma Blast in 2013, followed by the Holo Rare Dialga from Call of Legends in 2011. Fifth is Dialga G LV.X from Platinum in 2009, a Rare Holo LV.X. The leaders mix EX and GX cards, a Holo Rare from Call of Legends and a Level-Up holo.
Dialga card value comes from the Diamond & Pearl era first, which holds 8 of the twenty-five leading cards, followed by Sun & Moon with 7 and HeartGold & SoulSilver with 4. Black & White, XY and Sword & Shield hold 2 each. The newest era's leader is Dialga from Mega Evolution in 2025, which sits 46th overall. All 10 cards in the top ten and all 25 in the top twenty-five are modern, meaning they come from eras after the WOTC era.
Among the ten leading Dialga cards, the printed rarities split evenly across several groups: 2 LEGEND, 2 Rare Holo LV.X, 2 Secret Rare and 2 Ultra Rare, plus 1 Common and 1 Holo Rare. Widening to the leading twenty-five, Ultra Rare is the largest group with 6 cards, then Secret Rare with 5 and Common with 4. Holo Rare, LEGEND, Rare Holo and Rare Holo LV.X each have 2, with 1 Promo and 1 Rare filling out the rest.
By the value of its single leading card, Dialga ranks 36th of 1020 species with priced cards. By the combined value of its ten leaders it ranks 27th of 753. The higher placement by combined value shows that Dialga cards are valued less on one standout print than on the depth of the group behind it, with the top ten holding 79 percent of the species total.
