EB04 Secret Rare and Special Cards in EB-04 Egghead Crisis

The EB04 Secret Rare is a single card type: Bandai’s official page for EXTRA BOOSTER -EGGHEAD CRISIS- [EB-04] (EB04) lists 1 Secret Rare and 6 Special Cards among 67+1 card types, with 6 cards per pack. The Japanese edition released on January 31, 2026. This guide covers the rarity counts, the eight cards Bandai names, and how the box is built.

Key Facts: What Is EB-04?

EB-04 is the ONE PIECE CARD GAME Extra Booster called EGGHEAD CRISIS, sold in Japan as a Japanese edition set. The table below collects the names, code and contents, and each fact comes from Bandai’s own pages (English and Japanese) or from our product page.

If you want the sealed box rather than singles, our EB-04 Egghead Crisis Japanese One Piece Booster Box (update: currently sold out — restock requests via Quick Order) page lists the regular box. The rest of this guide explains what the rarity numbers mean before you choose.

How Many Secret Rare and Special Cards Are in EB-04?

EB-04 has 1 Secret Rare type and 6 Special Card types out of 67+1 card types, according to the official rarity breakdown.

Bandai prints the breakdown as a list of counts, one row per rarity. The table repeats those rows exactly and adds a plain-language note about what each row tells you. Every number here counts card types, meaning distinct cards in the set. None of them describes how often a card appears in a pack.

The arithmetic is simple. Add Special Cards (6), Leader (1), Secret Rare (1), Super Rare (9), Rare (21) and Common (29) and you get 67. The single DON!! Card is the “+1”, which brings the total to 68 entries. That matches the “67+1 types” line on both the English and Japanese official pages, so the breakdown is internally consistent.

Two readings follow from this table. First, the Secret Rare tier is as small as the Leader tier: one card type each. Second, the Special Cards tier is six types, which is smaller than the Super Rare tier at nine. A collector working through the set therefore has fewer top-tier cards to track than the card count of 67 might suggest. Commons and Rares make up 50 of the 67 non-DON!! types.

What Is the EB04 Secret Rare in Egghead Crisis?

The EB04 Secret Rare is the one card type in the Secret Rare row of the official breakdown, which means the set has exactly one Secret Rare design to chase.

Bandai’s page gives the Secret Rare as a count, and the card list on the same page names eight cards. Only two of those entries carry a version label: Leader Jewelry Bonney (EB04-001) as Normal and Alt-Art, and Koby (EB04-044) as a Super Alt-Art version. The other six entries are a name and a number. If you are logging a binder, record the card number first, because the number is what Bandai prints for every entry.

What the single Secret Rare slot means for a buyer is mostly about expectations. A sealed box is a random product, and our product page states that the specific cards in each box are randomly packed at the factory and that individual pulls are not guaranteed. A set with one Secret Rare type has one target in that tier, but the sealed product does not promise you will open it. If a particular card matters to you more than the box experience, that is a reason to think about singles instead of sealed product.

Do not confuse the three terms that appear near each other on the official page:

• Secret Rare is a rarity row with 1 card type.
• Special Cards is a separate rarity row with 6 card types.
• Super Alt-Art version is a version label printed next to Koby (EB04-044) in the card list.

They are three different pieces of information, and the official page presents them separately. Treat them that way when you search for cards or compare notes with other collectors.

Which EB-04 Cards Does Bandai Name?

Bandai names eight cards for EB-04: EB04-001 and EB04-002 Jewelry Bonney, EB04-013 Carrot, EB04-022 Issho, EB04-038 Rosinante & Law, EB04-044 Koby, EB04-052 Sanji and EB04-058 Borsalino.

The table lists them in number order with the exact label the official page prints. The Japanese page lists the same card numbers, and it lists the Koby card as a Super Parallel card, where the English page says Super Alt-Art version.

Jewelry Bonney, EB04-001 and EB04-002. Bonney appears twice in the list. EB04-001 is the Leader Card, the only Leader in the set, and it is shown in a Normal version and an Alt-Art version. EB04-002 carries the same character name at the next card number. Because the Leader row counts 1 type, the Leader is the card that opens the numbering.

Koby, EB04-044. This is the entry with the most unusual label. It is marked as a Super Alt-Art version on the English page, and as a Super Parallel card on the Japanese page.

Sanji, Borsalino, Carrot, Issho, and Rosinante & Law. These five entries are printed without any version label, as a name and a card number. Rosinante & Law (EB04-038) is the only entry that names two characters on one card.

A note on names: our product page names Kizaru among its key cards, and the official card list prints Borsalino for EB04-058. Rely on the card number to be sure you have the right card.

Which EB-04 Card Is Labelled Super Alt-Art?

Koby, EB04-044, is the card Bandai labels “Super Alt-Art version” among the eight cards it names for EB-04.

The wording differs between the two official pages. The English page says “Super Alt-Art version” next to Koby. The Japanese page lists Koby (EB04-044) as a Super Parallel card. Both pages attach their label to the same entry. For the Leader, the English page uses the plain label “Alt-Art” next to the Normal version, so the set shows three version words in total: Normal, Alt-Art and Super Alt-Art.

Where does this sit against the Special Cards row? The rarity breakdown gives Special Cards as 6 types. The card list does not state that Koby’s Super Alt-Art version is one of those six, so keep the two facts apart: the row count tells you how many Special Card types the set has, and the card list tells you which named cards have a labelled version. If you want a dedicated rundown of the parallel, SP and Secret Rare cards, our EB-04 Egghead Crisis parallel, SP and Secret Rare list covers that angle.

How Is an EB-04 Booster Box Built?

An EB-04 booster box holds 24 packs of 6 cards, which makes 144 cards per box, according to our product page.

The official pages describe the pack, not the box: one pack contains 6 cards, and the set has 67+1 card types. Our product page adds the box layer. The table keeps the two sources apart so you can see where each number comes from.

Check the multiplication: 24 packs times 6 cards is 144 cards, so the box figure agrees with the pack figure. Bandai’s notes on the page also say that cards are packed at random, that photos can differ slightly from the real product, and that product specifications may change. Our own page adds that this is a sealed randomized product.

The set has 67+1 card types, and the Secret Rare tier is only one of seven rows in the breakdown. Our product page says the box includes Leader cards from the Egghead arc plus Commons, Uncommons, Rares, Super Rares and Secret Rares with alternate-art parallels. Neither our page nor Bandai’s lists how many of any rarity a box contains, so this guide does not either.

Which EB-04 Cards Do Collectors Look For?

Our product page lists Dr. Vegapunk (all Satellites), Kizaru, Saturn, Bonney and Luffy as the key and chase cards for EB-04, along with Egghead-themed alt-art parallel cards.

That list is useful next to the official one because the two do not match name for name. Bandai’s page names Jewelry Bonney, Koby, Sanji, Borsalino, Carrot, Issho and Rosinante & Law. Our page names Dr. Vegapunk in all his Satellite forms, Kizaru, Saturn, Bonney and Luffy. Bonney appears in both lists.

So a practical way to use both lists is as a checklist of names to search. Start with the eight official card numbers, since those are printed by Bandai. Then add the characters from our key-card line. If you want pull-rate discussion and community chase rankings, our EB-04 chase cards guide is the place for that, and this guide stays with the official rarity structure.

Should I Buy the Regular Box or the Damaged Box?

Buy the regular box if the outer box matters to you, and buy the damaged box only if you want the cards and accept cosmetic damage with no returns.

Both products are the same set, EB-04 Egghead Crisis, in the Japanese Original Edition. The difference is the condition of the outer box.

For a collector who plans to keep the box sealed on a shelf, the regular box is the clear choice, because the outer box is part of what you are keeping. For someone who intends to open packs and sleeve the cards, the damaged box is the sensible alternative, since the listing says the cards inside are unaffected and the damage is cosmetic to the outer box.

Read the damaged-box terms before you order. The listing states that it is a discounted item sold as-is, that the photos after the first one are samples of damaged boxes from the same stock, and that returns and refunds are not accepted. The first image on that page shows the regular product so you can identify the set.

How Do Shipping and Payment Work for an EB-04 Order?

EB-04 orders ship from Tokyo by FedEx with tracking, and you pay in Japanese yen by Wise bank transfer, PayPal, or credit or debit card through PayPal.

The details come from our shipping policy and payment methods page:

• Standard shipping: FedEx International Connect Plus with tracking. FedEx transit after dispatch is usually 3-7 business days, an estimate and not a guaranteed date.
• Expedited shipping: FedEx International Priority with tracking, usually 2-5 business days after dispatch, also an estimate.
• Shipping cost: calculated automatically at checkout from your delivery address.
• Handling time: most orders are processed and shipped within 5 business days after PayPal or Wise payment has cleared. Business days exclude weekends and Japanese national holidays.
• Minimum order: there is no minimum order amount or quantity.
• Address: FedEx cannot deliver to P.O. Boxes, so enter a physical address.
• Customs: after handoff to FedEx, customs inspections and import procedures are controlled by the carrier and destination authorities and can delay delivery.

On payment, all charges are in yen. Wise bank transfer is the only method without the 5% payment processing fee, and PayPal and card payments carry that 5% fee. Cards accepted through PayPal are Visa, Mastercard, American Express and JCB, with the offered brand decided by PayPal for your country and card. For Wise, an order without a payment screenshot is cancelled automatically if payment has not arrived within 12 hours, and the window is 3 hours when the order includes a pre-order item. A Wise payment with an uploaded screenshot gives you 5 days to upload it and a price hold of 10 days in total. SWIFT payments incur a receiving fee of JPY 611, so add that amount to the order total.

How Should I Track EB-04 Rare Cards in a Binder?

Track EB-04 by card number first, then by rarity row, because the card number is the one identifier Bandai prints for every entry.

A simple method works with the official data. Make one line per rarity row, with the type count beside it: 6 Special Cards, 1 Leader, 1 Secret Rare, 9 Super Rares, 21 Rares, 29 Commons and 1 DON!! Card. That gives you a target of 68 entries. Then add the eight named card numbers as your first confirmed entries. When you find a card with a number that is not on the official list, add it to the correct row and cross-check the name against the card itself.

Keep the version labels in mind as you log. EB04-001 has a Normal and an Alt-Art version, so it can take two slots in a binder if you collect versions. EB04-044 is the Super Alt-Art version of Koby. Everything else in the named list is a single entry, as far as the official page shows. Our EB-04 booster box buying guide is the next read if your main question is whether to buy a box at all.

Finally, remember the edition. Everything on this page is about the Japanese edition, with Japanese card numbers in the EB04-xxx format. Bandai’s English-language page describes the same set under the Asia English site, and the numbers match across the English and Japanese pages. If you compare against a differently printed version of a set, match on the card number rather than on a character name.
