Are you a powerful enough Trainer to command what's been Unleashed?
Unleashed is the second expansion of cards released during the HeartGold & SoulSilver Series of the Pokémon Trading Card Game. It was released May 12, 2010. Unleashed does not have a formal expansion as its Japanese counterpart, as the majority of cards originate from decks and the remainder of the HeartGold Collection and SoulSilver Collection. Specifically, in addition to these two Collections, Unleashed brings together cards from the Battle Starter Decks, the Leafeon vs Metagross Expert Deck, Reviving Legends, and the Japanese Tyranitar and Steelix Constructed Standard Decks. The set introduces the Legendary beasts as brand new, dual-type Pokémon LEGEND cards, and continues to release Pokémon Prime. Alph Lithograph, originating from the SoulSilver Collection, is included as a secret card.

The Unleashed expansion is centered around the Legendary beast trio Entei, Raikou, and Suicune. In addition to being featured on the booster packs, these three Legendary Pokémon are included as the three Pokémon LEGEND. Starting with this expansion, Pokémon LEGEND represent two Pokémon each, cost two Prize cards when Knocked Out, and credit two illustrators per LEGEND. The Set Symbol is a combination of the three Pokémon's facial crests. Furthermore, the three's silhouettes are printed as Unleashed's Prerelease sleeves. The set continues to explore the Johto region throughout its artwork, and also includes a theme reminiscent of the Pokéathlon from the Pokémon games on the cards originating from the Battle Strength Decks. A digitized battle scene can be seen on the cards originating from the Leafeon vs Metagross Expert Deck. kawayoo provides the promotional artwork for the booster packs and the Theme Decks.
In addition to Pokémon LEGEND, Unleashed also includes Pokémon Prime, which are a powerful variant of Pokémon compared to their regular counterparts. The Unleashed expansion promoted six new Pokémon Prime cards: SoulSilver Collection's Crobat and Ursaring, and Reviving Legends' Kingdra, Lanturn, Steelix, and Tyranitar. Only these four Primes, their relevant pre-evolutions, and the six Pokémon Legend pieces were pulled forward from Reviving Legends. The two Tyranitar and the two Steelix cards pulled forward are the only cards of the Darkness-type and the Metal-type released in Unleashed. Since the HeartGold & SoulSilver expansion did not include these two types, they were the main types included in the Unleashed Theme Decks Chaos Control and Steel Sentinel.
