Eevee Heroes Explained | What Is Eevee Heroes, Moonbreon, and Highlights of Popular Cards
Eevee Heroes is a highly popular Japanese Pokémon Card expansion pack that features the Eevee evolutions (Eeveelutions) as its main focus. This article organizes the basic information of the set, how to view rarities, the positioning of “Moonbreon,” the price range of popular cards, and key points when looking at the Japanese market in an easy-to-understand manner.
What is Eevee Heroes?
Eevee Heroes is a Japanese expansion pack released on May 28, 2021.
The set contains a total of 101 cards (69 regular cards + 32 Secret Rares). Eevee and its evolutions take center stage, and the set has been highly evaluated for both its visual strength and character popularity.
This set is known not just for having many Eevee-related cards, but because the featured cards in the high-rarity tier are exceptionally strong. It is characterized by sustained collector demand for both unopened boxes and single cards.
How to View the Rarity Structure
The total of 101 cards in Eevee Heroes can be broadly understood through the following layers:
| Layer | Content | Highlights in this Set |
| Regular Cards | Common Pokémon, Trainers, and Energy | Forms the foundational baseline of the entire set |
| Pokémon V | Standard high-rarity slot for main-class Pokémon (Regular ver. + Full Art ver.) | The core supporting the popularity of the Eeveelutions |
| Pokémon VMAX | Only 4 types included: Umbreon, Sylveon, Glaceon, and Leafeon | Contains Rainbow versions and Special Illustration versions; high collection demand |
| Secret Rare Slot | Full Art types, Special Illustration types, high-rarity Trainers, etc. | The core section that drives up the value of the set |
※ Since this set is a product from before the VSTAR era, VSTAR cards are not included.
※ Also, the VMAX versions of Espeon, Vaporeon, Flareon, and Jolteon are not included in this booster pack; they were released in a separate product (VMAX Special Set Eevee Heroes). The only VMAX cards inside Eevee Heroes are Umbreon, Sylveon, Glaceon, and Leafeon.
When actually searching, confirming beforehand whether the VMAX you want is included in this set—not just checking the layers of “Regular,” “V,” “VMAX,” and “Secret Rare”—will prevent purchasing errors.
Espeon VMAX
What is Moonbreon?
An indispensable topic when talking about Eevee Heroes is the Special Illustration version of Umbreon VMAX, commonly known as Moonbreon.
In addition to the character popularity of Umbreon, the visual presentation evoking the nightscape and the moon is extremely strong, causing this card to frequently be treated as the symbol of the entire set.
The Eeveelutions inherently have a thick fan base, but among them, Umbreon commands particularly strong support including overseas, easily placing it as the “definitive card of Eevee Heroes.”
Estimated Price Range (At the time of writing)
The following is a rough guide based on sales data and overseas market prices at the time of writing. Actual prices fluctuate based on condition, centering, scratches, presence of grading, and exchange rates.
| Card | Rough Price Range |
| Umbreon VMAX Special Illustration Ver. (Moonbreon) | Frequently moves in the hundreds of thousands of yen range; graded items can go even higher. |
| Sylveon high-rarity cards | High tens of thousands to over a hundred thousand yen range. |
| Glaceon high-rarity cards | High tens of thousands to around one hundred thousand yen range. |
| Leafeon high-rarity cards | Low tens of thousands to high tens of thousands of yen range. |
While Moonbreon is sometimes discussed at lower market prices than before, in the reference data at the time of writing, it is in a price tier that can be hard to contain within just the “high tens of thousands of yen.”
Popular Cards Other Than Moonbreon
Aside from Moonbreon, there are other cards in this set with high collector popularity.
Sylveon high-rarity cards
Possessing a strong sense of flashiness, this type easily gathers demand centered on visual appeal among the Eeveelutions.
Glaceon cards with a special feel
Its cool color tones and translucent presentation are easily favored, attracting attention for its highly complete illustration.
Leafeon high-rarity cards
The visuals evoking nature and greenery are easily supported, maintaining stable popularity among the Eeveelutions.
Why Does Eevee Heroes Have Such a Strong Premium Feel?
The reason this set is viewed specially is because the strength of character popularity and the stunning looks of the high-rarity tier are perfectly balanced.
Each of the Eeveelutions has its own dedicated fans, creating a structure where multiple “wanted cards” easily arise within a single set.
Because of this, both unopened box demand and single card demand arise easily, making it a set that sustains long-term attention.
Key Points to Verify in the Japanese Market
When looking at Eevee Heroes in the Japanese market, checking the following will make it easier to make a judgment:
- Confirm the set name, not just the card name.
- Do not confuse the regular version with the Special Illustration version.
- Check for white chips and scratches via front and back photos.
- Separate unopened boxes and single cards in your thinking.
- Clearly see whether it is a graded item or ungraded.
Even for the same Umbreon or the same Sylveon, the price difference becomes large depending on the specification. Especially in the high-value tier, the quality of the listed photos is crucial.
Popular Sets are Easier to Understand by Viewing the Symbolic Card and Surrounding Popular Cards Together
Rather than looking only at Moonbreon, viewing Eevee Heroes while including surrounding popular cards like Sylveon, Glaceon, and Leafeon makes it easier to see why this set has remained so strongly favored for a long time.
Using Neokyo, you can collectively search for unopened boxes and single cards of Eevee Heroes listed on Japanese shops and flea markets.
