About the Set
HS Undaunted is the smallest HGSS set at 90 numbered cards. Its six Pokémon Prime run 81–86 and include Espeon Prime and Umbreon Prime, both long-standing collector favourites. Two Pokémon LEGEND close the set: Kyogre & Groudon and Rayquaza & Deoxys. A secret-rare Alph Lithograph numbered THREE completes it.
How LEGEND cards work: each LEGEND is a single card split across two halves, numbered separately. You need both halves in play together to use it, so each half appears as its own entry in the gallery below.
Prime, LEGEND & the Alph Lithograph
HS Undaunted had a single print run. Its chase cards are the six Pokémon Prime, the two Pokémon LEGEND and the secret-rare Alph Lithograph.
| Type | What it means |
|---|---|
| Pokémon Prime (81–86) | Espeon, Houndoom, Raichu, Scizor, Slowking and Umbreon — holo rares with their own foil treatment. |
| Pokémon LEGEND (87–90) | Kyogre & Groudon and Rayquaza & Deoxys, each split across two separately numbered halves. |
| Secret rare (THREE) | The Alph Lithograph, the third in the four-part HGSS series. |
Note: the gallery below covers all 91 cards. Each LEGEND appears as two entries, one per half.

HGSS Black Star Promos use their own numbering (HGSS01 onward) and carry a black star where a set symbol would be.
Collecting & Where to Buy
HS Undaunted is out of print and trades on the secondary market. Common singles are inexpensive, while Umbreon Prime and Espeon Prime command the highest premiums, with the two LEGEND cards close behind.
Collector tip: Umbreon Prime (86/90) is the card to watch — check the edges and surface closely, and confirm it is the Prime rather than a regular holo.
