Karoo OP-18: Character Cards Guide

Updated November 9, 2026

OP-18 The Dominance of God (Japan release: November 21, 2026): see our OP-18 release date guide and OP-18 card list of revealed cards.

Karoo OP18 refers to the Leader card OP18-001 Karoo (Animal/Albasta) in the One Piece Card Game set BOOSTER PACK -THE DOMINANCE OF GOD- [OP-18] (OP18). The official page describes it as a fast-paced deck and lists Nefeltari Vivi (OP18-011) and Karoo (OP18-004) as its suggested combos.

OP-18 is not out yet, so this guide stays on Karoo and covers only what the official pages state about the character. For the whole set, read the OP-18 complete guide. If you want a sealed Japanese One Piece box to open now, the OP-17 The World’s Strongest Warriors booster box is a different set that is available today.

What Is the Karoo OP18 Card?

The Karoo OP18 card is OP18-001 Karoo, a Leader of type Animal/Albasta, shown as one of the new Leaders for the set. The official English product page highlights it, and the Japanese page lists the same card as カルー with the type Animal / Alabasta Kingdom.

The official pages give no effect text, power, color or rarity for Karoo. The table above is the full official picture for now.

The official line for the Karoo Leader is about speed. The English page puts Karoo among the new Leader cards of the set, next to All Sunday, and the Asia English page counts six Leader cards in total. That makes Karoo one of six Leaders in a set of 127+1 types.

Which Karoo OP18 Cards Are Listed So Far?

Two Karoo cards are listed so far: the Leader OP18-001 and a second card numbered OP18-004. The official pages name OP18-004 only as a combo partner for the Leader, so its role in a deck is not described.

The English, Japanese and Asia English pages all repeat the same two combo numbers. Because three official pages agree on OP18-011 and OP18-004, those are the numbers to remember. The pages do not give a rarity for either card, so none is stated here.

The official pages use the card number to tell entries apart, so always write the number next to the name when you note a card down. “Karoo” alone could mean OP18-001 or OP18-004.

How Does the Karoo OP18 Leader Pair With Nefeltari Vivi?

The official page lists Nefeltari Vivi OP18-011 and Karoo OP18-004 as suggested combos for the Karoo Leader. That is the whole official statement: two card numbers named as combos, with no effect text published to explain how they work together.

The combo list has a clear shape: one entry is a second Karoo card, OP18-004, and the other is Nefeltari Vivi, OP18-011. Both are named on the English, Japanese and Asia English pages.

If you are planning a Karoo deck, the practical step is to note three card numbers: OP18-001, OP18-004 and OP18-011. Check the effect text once the official card list shows it.

What Does “Fast-Paced Deck” Tell You About the Karoo Leader?

It tells you the Karoo Leader is presented as a speed-focused build, and nothing more detailed than that. The official line is a short description, not a rules text, so it should be read as a direction rather than a promise about how the deck plays.

Here is what the three official pages give and what they leave out.

For a collector, this means the Karoo cards are best treated as named cards with known numbers and an unknown rarity. For a player, it means the deck idea is clear but the build is not. Both groups should wait for the official card list before deciding anything.

The English page also lists alt art with original artwork by Yoshitaka Amano as part of the set. It does not connect that artwork to Karoo, so do not assume a Karoo alt art exists.

When Does the Karoo OP18 Leader Release?

The English site lists OP-18 for November 20, 2026, while the Japanese site and the Asia English site list November 21, 2026 (Saturday). The Japanese release is the one for Japanese edition cards, which is the edition this guide covers.

The English page adds that cards are legal 7 days after the release date in your region. It also notes that multiples of one card may appear, a full set may be hard to assemble, illustrations may differ from the final product and product details may change. The Japanese launch event runs November 21 to December 6, 2026 at official shops nationwide, according to the official news page. For a closer look at how the English and Japanese dates compare, see our OP-18 English vs Japanese release guide.

How Much Does an OP-18 Pack Cost and What Is in It?

An OP-18 pack lists at USD $4.99 MSRP on the English site and 240 yen with tax on the Japanese site, and each pack holds 6 cards. Those are the two official price points, and they come from two different regional pages.

The set contains 127+1 types in total. The English page lists the rarity groups as Commons, Uncommons, Rares, Super Rares, Secret Rares, Leaders, Specials, Treasure Rare and a DON!! Card. The Asia English and Japanese pages give the counts for each group, shown in the next section. For the question of how often each rarity appears, our guide to OP-18 pull rates and what is confirmed covers what is official.

Where Does Karoo Sit Among the Other OP-18 Leaders and Rarities?

Karoo is one of six Leader cards in OP-18, a set with 127+1 types, 6 cards per pack, and the themes Water Seven and the Holy Knights of God.

That breakdown comes from the Asia English page, and the Japanese page lists the same counts. The English page also names All Sunday as a new Leader. Which of the six Leaders is the Karoo card in rarity terms is not stated, since the pages do not give Karoo a rarity.

Water Seven and the Holy Knights of God are the two themes the English page names for the set. The Saint Gunko OP18-065 image below is an official reveal image of another card from OP-18, and our Secret Rares and Amano alt art article separates reported cards from official ones.

Which Other OP-18 Character Guides Should You Read Next?

Read the guide for the Leader or character you plan to play, because each one covers a different card number range. These are the related OP-18 articles on this site:

• OP-18 Leader cards: Franky, Luffy, Miss All Sunday and Gunko, the overview of the other new Leaders.
• Luffy OP-18 cards and Franky OP-18 cards.
• Miss All Sunday OP-18 cards, the All Sunday Leader named on the English page.
• Gunko OP18 cards, for the Saint Gunko card shown above.
• Robin OP-18 cards and Lucci OP-18 cards.

What Official OP-18 Products Does the English Site List Around Release?

The English site lists the single booster pack and the Double Pack Set Vol.13 [DP-13] for OP-18. DP-13 releases November 20, 2026 at USD $11.99 MSRP and holds two OP-18 booster packs plus one DON!! Card, in packaging that doubles as a card case (official DP-13 page).

DP-13 lists 2 types of content: the booster packs and the DON!! Card. The pack price on the English site is $4.99, so the two-pack set is a separate product with its own MSRP rather than a different pack. Neither page says which Karoo cards, if any, will appear in a given pack.

What Is the 4th Anniversary Event for OP-18?

The 4th Anniversary Event (OP-18 Release Event) celebrates the release of THE DOMINANCE OF GOD [OP-18] and runs November 20 to December 17, 2026. Players can apply through TCG+ starting November 6, 2026 (official event page).

Participation prizes are the 4th Anniversary Tournament Pack (75 types in total), the 4th Anniversary Promo Card P-161 Monkey.D.Luffy, a 4th Anniversary Leader Card, and World United DON!! Cards (EN_03, EN_04). The winner prize is P-161 Monkey.D.Luffy in Silver foil with a Gold stamp. None of these listings states a Karoo card as a prize.

What Japanese One Piece Boxes Are Available While You Wait?

While OP-18 is unreleased, the related sets OP-17, OP-16 and OP-15 are available now as Japanese sealed products. They are different sets and contain no OP-18 cards.

The official OP-18 page lists OP-17 as a related set, which is why OP-17 is the natural comparison. Our OP-18 or OP-17 box guide walks through that choice.

How Do Shipping and Payment Work for Those Sets?

Orders ship by FedEx with a tracking number, and all payments are made in Japanese yen. Our shipping policy lists two services: FedEx International Connect Plus (usually 3-7 business days after dispatch) and FedEx International Priority (usually 2-5 business days).

These transit times are estimates only, and delivery dates shown on the site, at checkout or in carrier tools are estimates as well. Shipping cost is calculated automatically at checkout based on your delivery address. Most orders are processed and shipped within 5 business days after PayPal or Wise payment has cleared, which is also an estimate. FedEx cannot deliver to P.O. Boxes, so a physical address is needed. There is no minimum order amount or quantity.

On the payment methods page, Wise bank transfer is the only method without the 5% payment processing fee. PayPal and card payments through PayPal (Visa, Mastercard, American Express, JCB, as offered by PayPal) carry that 5% fee. Any difference between the charged amount and your statement comes from exchange rates and fees set by your payment provider.

How Should You Prepare a Karoo Deck Plan Before Release?

Start with the three card numbers the official pages give: OP18-001 Karoo, OP18-004 Karoo and OP18-011 Nefeltari Vivi. Everything else about the deck, including effects, power and rarity, is not published in the official material.

1. Write down OP18-001, OP18-004 and OP18-011 so you can find them in the card list once it is published.
2. Decide which edition you play. The Japanese edition releases November 21, 2026, and the English site lists November 20, 2026.
3. Remember the English page note that cards are legal 7 days after the release date in your region.
4. Keep in mind the official warning that multiples of one card may appear and a full set may be hard to assemble.

Karoo is described only as a fast-paced deck. Read the effect text on the official card list before you commit to any build, and use the official pages as your reference for the set.

What Is the Bottom Line on Karoo OP18?

Karoo OP18-001 is a fast-paced Animal/Albasta Leader, with OP18-004 Karoo and OP18-011 Nefeltari Vivi as its official combos. Release is November 20 on the English site and November 21 on the Japanese site, so watch the official OP-18 page for card details.
