One Piece OP-17 The World's Strongest Warriors: What to Grade

One Piece OP-17 The World's Strongest Warriors: What to Grade

One Piece Card Game turns four this summer, and Bandai is marking the anniversary by putting five of the story's biggest names on Leader cards at once: Whitebeard, Luffy, Shanks, Kaido, and Big Mom, one per color. OP-17, The World's Strongest Warriors, also introduces a second Treasure Rare, the rarity tier that debuted with a single card in OP-16. Here is what is confirmed, what is still a rumor, and what to actually submit once packs are in hand.

What OP-17 Is: One Set, Five Emperors

OPCG launched in July 2022, so the set landing in late August 2026 doubles as the 4th anniversary release. Bandai built the theme around the old guard: instead of one arc's cast, OP-17 pulls the series' most recognizable power players into a single 6-Leader lineup. Five of those six Leaders are already confirmed, and each one leads a different color:

Leader	Color	Card Number
Edward Newgate (Whitebeard)	Red	Unrevealed
Monkey D. Luffy	Black	Unrevealed
Shanks	Green	OP17-022
Kaido	Purple	Unrevealed
Charlotte Linlin (Big Mom)	Yellow	Unrevealed
Sixth Leader	Unconfirmed	Unconfirmed

A five-color Emperor lineup is a deckbuilder's dream and a collector's checklist at the same time. Players get a Leader in every color built around the character they already run support cards for. Collectors get a "complete the set" chase that did not exist in prior main sets, since no earlier OP-17-style release stacked this many franchise-defining names into one Leader slot at once.

The set's subtitle also lines up with where the manga and anime currently sit. Elbaf, the giants' homeland, is the arc supplying this set's new faces, including Loki below, while the anniversary framing pulls in the established Emperors as a nostalgia play. That combination, new arc content plus returning heavy hitters, is exactly the mix that tends to move both the playerbase and the collector base at once, and it is why OP-17 is drawing preorder attention well ahead of most main sets at this point in their cycle.

Release Date and How to Buy In

Bandai's official product listing puts the English release at August 28, 2026, with a pre-release weekend on August 21. That is roughly six weeks out as of this writing, which puts OP-17 firmly in the preorder window rather than the post-release singles market. MSRP is $4.99 per pack, in line with recent OPCG main sets.

The bigger story for collectors is the launch structure itself. Community trackers describe OP-17 as the first One Piece main set built for a single worldwide street date instead of a Japan-first rollout followed by an English release weeks later. If that holds, it changes the early price dynamic collectors have gotten used to: no more weeks of Japanese secondary-market prices setting the tone before English packs even hit shelves. Preorder now if you want box allocation; do not chase Japanese singles at a premium expecting an early information edge, because that edge is smaller this time.

The New Treasure Rare Tier

OP-16 introduced the Treasure Rare with a single card, Vista, sitting above Secret Rare in the pull-rate hierarchy. Our OP-16 chase card guide covered it as a total unknown at the time, since nobody had graded one yet.

Treasure Rare (unrevealed). OP-17 carries exactly one Treasure Rare slot, and Bandai has not named the card as of this writing. Given the anniversary framing and the five-Emperor Leader lineup, expect the TR to go to one of those five characters, or possibly a sixth marquee name held back for the reveal. Grading history is thin. Vista TR examples from OP-16 are still building a population report, so anyone chasing the OP-17 TR is buying ahead of any real PSA 10 data. Sleeve it the moment it is pulled and wait for community grading results before paying a submission fee.

Vista's early run is worth watching as a preview of how the OP-17 TR will behave. Japanese listings for Vista scattered widely in the weeks right after OP-16 released, with no consensus price forming until the first batch of PSA and CGC submissions came back. Expect the same pattern here: a volatile few weeks of raw pricing, then a market that settles once graders start publishing population numbers. That lag is exactly why a brand-new rarity is a hold, not a submit, in the first month.

Loki: The Set's Confirmed Secret Rare

Loki (OP17-119). A Black Character, Cost 6, Power 8000, with Giants and Elbaf traits and a reported ability that knocks out an opponent's character with total cost 4 or less when played. Card trackers surfaced these details from Japanese leak networks; Bandai has not put out an official spoiler for this card yet, so treat the exact wording as provisional until street date.

The story hook is real regardless of final wording. Loki is Elbaf's disgraced prince, the "Shame of Elbaph," defeated and imprisoned by Shanks years before the current arc. He later crosses paths with Luffy, who reads him as more complicated than the villain label suggests. That puts Loki in direct narrative orbit with two of this set's five Leaders, which is exactly the kind of crossover appeal that pulls collector demand beyond the playerbase. Only two Secret Rare slots exist in OP-17, and Loki is the one confirmed so far.

The Manga Rare Emperors: What History Tells Us About Value

Community reporting out of Japan has all four of the anniversary Emperors, Whitebeard, Shanks, Kaido, and Big Mom, receiving Manga Rare parallel treatments in OP-17, continuing a tradition every main set has carried since early OPCG. None of this is Bandai-confirmed on the record yet, so read it as well-sourced expectation rather than fact.

Shanks. If the report holds, this would be Shanks's third Manga Rare or SP-tier alternate art since launch. His prior SEC-SP and SR-SP versions already trade well over ¥200,000 on the Japanese secondary market, roughly four figures in dollar terms. That is the strongest historical precedent in the set for what a new Shanks chase can do once graded copies start circulating.

Whitebeard, Kaido, and Big Mom. Each carries deep standalone demand: Whitebeard as the symbol of the old-guard Emperors, Kaido as the game's most requested "strongest creature" pull, Big Mom as the character completionists need to finish the four-Emperor set. If all four land as Manga Rares, expect the same dynamic OP-16 saw with its three Admiral Manga Rares: players want one for the deck, collectors want all four for the wall, and that dual demand holds a price floor through the first year regardless of tournament relevance.

Grading OP-17: What to Watch For

The mechanics have not changed since our One Piece TCG grading guide: Bandai's cut tolerances run wider than the Pokemon Company's, so pack-fresh centering on a Leader or Manga Rare lands closer to 1 in 8 for a true PSA 10 read than 1 in 3. Glossy, full-bleed art on Manga Rares and alternate-art Leaders shows print lines under a grading lamp that a flat scan will miss.

Two things are specific to this set. First, five Leaders sharing one anniversary spotlight means five separate populations to track once grading data starts coming in, not one. Do not assume Whitebeard's PSA 10 rate will match Shanks's just because they shipped in the same set; centering variance is per-card-number, not per-set. Second, the Treasure Rare and any confirmed Manga Rares are new print runs with zero grading history on release day. Scan every pull before deciding what to submit, and lean on a confident scan-predicted overall rather than a gut read, especially on the TR.

Sealed vs Singles: Playing the Preorder Window

Six weeks out, the honest move for most collectors is patience. Preordering a box locks in MSRP before scalper markup hits, which matters more for a set this hyped than usual. Buying singles now means paying a premium for cards whose rarity slot, let alone their pull rate, is not fully confirmed.

The exception is anyone specifically chasing Shanks. If the third Manga Rare report is accurate, the character's track record justifies early positioning even at a markup, because demand for Shanks chases has never cooled between print runs. For everything else, including the unrevealed Treasure Rare and the sixth Leader, wait for street date.

What's Still Unconfirmed

Be clear-eyed about how much of OP-17 is still a question mark. The sixth Leader has no name attached. The Treasure Rare card is unnamed. The second Secret Rare slot beyond Loki is unfilled. And the Manga Rare status of the four Emperors, while well-sourced, is community reporting, not a Bandai spoiler drop. Expect the full picture to firm up over the next few weeks as Bandai's official card finder updates. Anything priced today off a leaked card list is a projection, not a market.

The ZeroPop Verdict: What to Grade and What to Wait On

The safest early bet is the Manga Rare Emperors, if Bandai confirms the report: four characters with deep, independent fan bases and a track record (via Shanks) of holding value across print runs. The riskiest early bet is the Treasure Rare, purely because there is no grading precedent yet and the card itself is unnamed.

Loki is the one confirmed Secret Rare, and the Elbaf storyline gives it crossover pull beyond players who just want the KO effect. It is a reasonable target once English packs are in hand and centering data starts to show up in the pop reports.

For everyone else, the right move for the next six weeks is to preorder sealed product at MSRP, resist paying a premium for leaked-list singles, and scan every chase the day it is pulled. See PSA vs BGS vs CGC for grader choice once you are ready to submit.

Frequently Asked Questions

When does One Piece OP-17 release in English?

Bandai's official listing puts the English release at August 28, 2026, with a pre-release weekend on August 21. Community trackers describe this as the first main OPCG set built for a simultaneous worldwide launch rather than a Japan-first rollout.

Who are the confirmed Leaders in OP-17?

Five of six: Edward Newgate (Whitebeard) in Red, Monkey D. Luffy in Black, Shanks in Green (OP17-022), Kaido in Purple, and Charlotte Linlin (Big Mom) in Yellow. The sixth Leader has not been revealed as of this writing.

What is the Treasure Rare in OP-17?

A new rarity slot sitting above Secret Rare, with exactly one copy in the set. OP-16 introduced the tier with the Vista card. Bandai has not named the OP-17 Treasure Rare yet, so treat any price talk around it as pure projection until it is revealed.

Is Loki a confirmed card?

Loki (OP17-119) is reported as a Black Secret Rare Character, Cost 6, Power 8000, with a KO ability against low-cost opponents, sourced from Japanese card-tracker leaks rather than an official Bandai spoiler. Treat the exact stat line as provisional until Bandai's official reveal.

Are the four Emperor Leaders also getting Manga Rare versions?

Community reporting says yes for Whitebeard, Shanks, Kaido, and Big Mom, but Bandai has not confirmed it on the record. If it holds, it continues the Manga Rare tradition every OPCG main set has carried, with Shanks's prior versions already trading well above ¥200,000 as the strongest value precedent in the set.

Should I buy OP-17 singles now or wait for release?

Wait, with one exception. Rarity slots and pull rates are not fully confirmed six weeks out, so today's leaked-list prices are projections. The exception is Shanks, whose grading and resale track record across two prior Manga Rare style prints justifies early positioning even at a premium. For everything else, preorder sealed at MSRP and price singles once the set is actually in hand.
