Quick answer: OP17 (The World’s Strongest Warriors) is the One Piece Card Game 4th anniversary set, pre-releasing 21 August 2026 and fully releasing 28 August 2026. Data is currently from one documented first-release box (24 packs + a double pack), which produced 2 Super Rares, 2 alt art rares, a Golden DON!!, a Rocks DON!!, a Shanks manga-style special art, and two Panda Man secret alt arts. This was a hot box — treat the numbers as early observations, not averages. We will add per-box rates as pre-release and launch-week openings come in.
Data status: Sample size is 1 box (26 packs) as of publication. This is deliberately published early to capture release-week interest — the pull rate figures below describe what a single box produced, not a statistical average. Check back through late August 2026 as we fold in additional box and case openings.
What Is OP17 — The World’s Strongest Warriors?
OP17, officially titled The World’s Strongest Warriors, is the One Piece Card Game’s 4th anniversary booster set. It pre-releases on 21 August 2026 and fully releases on 28 August 2026. The set is built around the Four Emperors and the Elbaf arc, and it introduces a deep, self-contained Rocks Pirates archetype — openers noted you can build an entire Rocks deck using only cards from this set.
As an anniversary set, OP17 is unusually stacked with playable cards across every colour. Early openers repeatedly described it as “mostly just full of good cards,” with new leaders for Kaido, Shanks, Charlotte Linlin (Big Mom), and Sengoku, plus staple characters and events for Rocks, Elbaf, and the Emperor crews.
The set also debuts a new collector layer: hidden Panda Man alternate arts, where a common card’s slot is secretly replaced by a Panda Man variant. This gives OP17 an easter-egg chase on top of the usual rarity ladder — more on that below.
OP17 set highlights
- Occasion: One Piece Card Game 4th anniversary set
- Theme: The Four Emperors and the Elbaf arc, with a full Rocks Pirates archetype
- New leaders: Kaido, Shanks, Charlotte Linlin (Big Mom), and Sengoku confirmed
- New collector chase: Panda Man secret alternate arts hidden in common slots
- Top chase card: Charlotte Linlin (Big Mom) alternate art — “going to be in everything”
- Premium special art: Shanks manga-style special (a 1-of-2 premium hit)
- Special DON!!: Golden DON!! and Rocks DON!! confirmed from the DON!! pack
- Pre-release: 21 August 2026 · Full release: 28 August 2026
Box Contents & Pack Structure
OP17 follows the standard One Piece TCG booster format:
- Booster Box — 24 packs per box, 12 cards per pack
- Double Pack Set (Vol.12) — 2 booster packs + 1 DON!! pack (the DON!! pack is where Golden DON!! and Rocks DON!! appear)
- Case — 12 boxes (288 packs), following the usual One Piece case structure
Each pack contains a mix of Commons, Uncommons, Rares, and a foil hit slot, with leader cards, alt art parallels, Super Rares, Secret Rares, manga-style special arts, and the DON!! cards sitting above that. OP17 adds the Panda Man secret alt art layer, which appears to replace a common slot rather than the main hit slot — meaning a Panda Man alt does not cost you your SR or alt art in that pack.
The DON!! pack is included with double packs, not loose blisters. If the Golden DON!! or Rocks DON!! is on your list, buy double packs.
Top Chase Cards in OP17
Prices are not yet established at pre-release — the figures firm up in the days after the 28 August 2026 launch. The list below ranks the cards drawing the most collector and competitive attention from the first opening.
| Card | Rarity / Type | Why It’s Chased | Market Price (USD) |
|---|---|---|---|
| Charlotte Linlin (Big Mom) — Alt Art | Alt Art | Called “insane” and “going to be in everything” — a 5-cost 7k lose-lose play effect; the set’s headline chase | Pre-release — TBC |
| Shanks — Manga-style Special Art | Special / Manga | Premium 1-of-2 art (griffin attack); the double-pack highlight of the first box | Pre-release — TBC |
| Edward Newgate (Whitebeard) — SR + Alt Art | Super Rare | Quake-quake fruit foil with cracking texture; the box’s repeat SR, plus an alt art version exists | Pre-release — TBC |
| Nico Robin — Alt Art | Alt Art | “10 out of 10 art”; strong 12-cost payoff character in the Elbaf/giant shell | Pre-release — TBC |
| Golden DON!! / Rocks DON!! | Special DON!! | Foiled DON!! chase cards from the DON!! pack; Rocks DON!! ties into the set’s marquee archetype | Pre-release — TBC |
| Panda Man Secret Alt Arts | Secret Alt Art | Hidden easter-egg variants of vanilla commons; collector novelty, “one in every colour” | Pre-release — TBC |
| Charlotte Pudding | Rare (playable) | “Basically an SR” — 3-cost 4k, on-play draw-three searcher; buy as a single for play | Pre-release — TBC |
| Kaido / Shanks / Charlotte Linlin Leaders | Leader (+ parallels) | New anniversary leaders anchoring Rocks and Emperor decks; alt art parallels exist | Pre-release — TBC |
Buy singles, don’t chase: The cheapest competitively playable OP17 cards — Charlotte Pudding, the Rocks 2k counters, Ben Beckman, Jack — are far cheaper as singles than the expected cost of hunting them through packs. Chase sealed only for the opening experience or the Panda Man / DON!! easter eggs.
OP17 Pull Rate Data by Rarity
Bandai does not publish official hit rates for One Piece TCG. The table below reflects one documented OP17 box (24 booster packs plus a bonus double pack, 26 packs total). This is a small, lucky sample — the “This Box” column is what actually came out, and the “Expected Per Box” column will be filled in once multiple boxes are opened. Read these as early observations, not guarantees.
| Card Type | This Box (26 packs) | Expected Per Box | Notes |
|---|---|---|---|
| Super Rare (SR) | 2 (Edward Newgate ×2) | To be confirmed | Both SRs in this box were Whitebeard; One Piece boxes typically land several SRs with some names recurring |
| Leader (standard) | Multiple | To be confirmed | Kaido, Shanks, Charlotte Linlin, and Sengoku leaders all seen across the box |
| Alt Art Rare / Parallel | 2 (Charlotte Linlin, Nico Robin) | To be confirmed | Alt arts occupy a rare slot and do not appear to replace the base SR |
| Secret Rare (SEC) | 1 (Rocks DON!! secret / normal art) | To be confirmed | A secret Rocks DON!! normal-art card was identified; standard SEC rate not yet established |
| Manga-style Special Art | 1 (Shanks, 1-of-2) | To be confirmed | Pulled from the bonus double pack; a premium, case-level-rarity target |
| Panda Man Secret Alt Art | 2 | To be confirmed | New OP17 easter egg; replaces a common slot. Two appeared in this box (one in the main box, one in the double pack) |
| Special DON!! (Gold / Rocks) | 2 (Golden DON!!, Rocks DON!!) | To be confirmed | Found only in the DON!! pack from double packs, not loose blisters |
First Box Opening Results
The dataset for this initial guide is a single first-release OP17 box (24 packs) opened alongside a bonus double pack (2 packs + DON!! pack). Notably, this box was hot — one opener pulled the majority of the premium hits. Documented pulls:
- Edward Newgate (Whitebeard) SR — pulled twice, including the quake-quake “cracking” foil treatment
- Charlotte Linlin (Big Mom) alt art — the box’s headline hit; also confirmed as an Edward Newgate SR earlier
- Nico Robin alt art — praised as “10 out of 10 art”
- Golden DON!! and Rocks DON!! — both special DON!! cards from the DON!! pack
- Shanks manga-style special art — a 1-of-2 premium, pulled from the double pack
- Two Panda Man secret alt arts — one in the main box (a Jaguar D. Saul common slot) and one in the double pack
- New leaders seen throughout: Kaido, Shanks, Charlotte Linlin, Sengoku
Summary: 2 SRs, 2 alt art rares, a secret Rocks DON!!, a Golden DON!!, a Shanks manga special, and two Panda Man alts across 26 packs. Openers themselves flagged this as an exceptional box (“the best double pack we’ve ever had”), so it sits at the lucky end of the distribution. Do not size your buying decisions off one box — the per-box average will land lower, and we will publish it as more openings come in.
The Panda Man Secret Alt Arts
The most interesting new feature in OP17 is the Panda Man secret alternate arts. Instead of the expected common, a card’s slot is replaced by a hidden Panda Man variant — an easter-egg rarity that isn’t advertised on the rarity ladder. In the first box, one appeared in a Jaguar D. Saul common slot, and a second confirmed in the double pack.
The working community theory from the opening: OP17 has exactly six vanilla common cards (all 2,000-power, the only true vanillas in the set), and each is expected to have a Panda Man alt. That would make the six vanilla commons a self-contained collector sub-set — easy to chase “one in every colour,” and a way to add value and fun to otherwise ignorable commons. This theory is not yet confirmed across the full set; we will update once more of the six are documented.
For strategy: Panda Man alts appear to replace a common slot, so they do not cost you an SR or alt art hit. Treat them as a bonus windfall rather than something to open toward.
Should You Open OP17 or Buy Singles?
Open OP17 if…
- You want the 4th anniversary opening experience — dense playable pools and strong artwork across every colour
- You’re hunting the Panda Man secret alts or the Golden / Rocks DON!! easter eggs, which are opening-only novelties
- You’re building a Rocks Pirates deck — openers noted the archetype can be built almost entirely from OP17
- You want a realistic shot at leaders and mid-tier alt arts to seed a collection
Buy singles if…
- You want a specific chase — the Charlotte Linlin alt art or Shanks manga special will cost far more to pull than to buy once prices settle
- You need competitive staples — Charlotte Pudding, the Rocks 2k counters, Ben Beckman, and Jack are cheaper as singles than the margin on chasing them
- You only care about one colour or archetype and don’t want the rest of the box
The honest bottom line
OP17 looks like a genuinely fun anniversary set to open — the Panda Man easter egg, a self-contained Rocks archetype, and heavy artwork give every box something to chase. But the box we have data for was a lucky one, and no set is a good way to acquire a named chase card. If you want the Charlotte Linlin alt art or the Shanks manga special specifically, buy the single after launch. If you want the experience, the DON!! and Panda Man hunts, or a Rocks deck, open a box or two and enjoy it — just set a budget and don’t expect this box’s results.

Frequently Asked Questions
When is the OP17 (The World’s Strongest Warriors) release date?
OP17, officially titled The World’s Strongest Warriors, pre-releases on 21 August 2026 with full release on 28 August 2026. It is the One Piece Card Game 4th anniversary set, built around the Four Emperors, the Elbaf arc, and a Rocks Pirates archetype. Booster boxes are the standard 24 packs, with a Double Pack Set (Vol.12) sold alongside.
How many hits are in an OP17 box?
Data is currently limited to one documented box (24 packs + a bonus double pack). That box produced 2 Super Rares (both Edward Newgate / Whitebeard), multiple new leaders, 2 alt art rares (Charlotte Linlin and Nico Robin), a Golden DON!!, a Rocks DON!!, a Shanks manga-style special art, and two Panda Man secret alt arts. This was an unusually hot box — do not treat it as the average. Per-box averages will be added as more openings come in.
What are the Panda Man alt arts in OP17?
OP17 hides secret Panda Man alternate arts — a collector easter egg where a common card’s slot is replaced by a Panda Man variant. In the first box, Panda Man alts appeared in place of vanilla commons (a Jaguar D. Saul slot, plus a second in the double pack). The working theory is that the set’s six 2,000-power vanilla commons each get a Panda Man alt. They’re chase collectibles driven by rarity and novelty, not competitive play.
What are the top chase cards in OP17?
The standout chase is the Charlotte Linlin (Big Mom) alternate art — openers called it “insane” and “going to be in everything.” Other top targets: the Shanks manga-style special art (a 1-of-2 premium), the Edward Newgate (Whitebeard) SR and its alt art, the Nico Robin alt art, the Golden and Rocks DON!! cards, and the Panda Man secret alts. Charlotte Pudding is flagged as “basically an SR” for play value.
Should you open OP17 or buy singles?
Open OP17 for the experience — anniversary artwork, Rocks Pirates support (a Rocks deck can be built almost entirely from this set), and the Panda Man easter-egg hunt. Buy singles for any specific chase: pulling a named card like the Charlotte Linlin alt art or the Shanks manga art through packs costs far more on average than the single once prices settle after 28 August 2026. Prices are not yet established at pre-release.
How does OP17 compare to OP16 (The Time of Battle)?
OP16 introduced Treasure Rares to Japanese product and centred on Marineford. OP17 is the 4th anniversary set built around the Four Emperors, Elbaf, and a self-contained Rocks Pirates archetype, and it adds the Panda Man secret alt arts as a new collector layer. Firm hit-rate comparisons aren’t possible yet — OP17 data is a single box, while OP16 has box and case-level data. This page updates as OP17 openings accumulate.
