Two Necrozma forms, two enhanced expansions, released in Japan on the exact same day — that’s the setup behind SM5S Ultra Sun and its twin, SM5M Ultra Moon.
Ultra Sun (SM5S) landed on December 8, 2017, as the Sun & Moon series’ fifth main expansion, and it’s the half of the pair built around Dusk Mane Necrozma GX — the fused Necrozma-Solgaleo form making its Pokemon TCG debut here. The set is also where Prism Star, a rarity that never existed before this release, first appeared on cards, headlined by the Prism Star Trainer card Akagi. Add in Sinnoh-region callbacks like Dialga GX and the Trainer SR Mars, and Ultra Sun packs a lot of firsts into one release.
This guide covers what’s actually in SM5S Ultra Sun, its headline chase cards, how it differs from its same-day twin Ultra Moon, and what buying into this set looks like from Japan today. We ship Japanese Pokemon singles and sealed product out of Tokyo, and the pricing below reflects our own current listings.
If you’re new to how the Sun & Moon era structured its releases, the short version is this: Japan split each “chapter” of the game generation into paired enhanced expansions that shared a release date and a set of design conventions — card numbering, pack pricing, and rarity tiers included — while each half carried its own distinct headline cards. Ultra Sun and Ultra Moon are one of the clearest examples of that format, since the split follows the same Dusk Mane / Dawn Wings Necrozma divide that defined the video games they’re based on.
SM5S Ultra Sun released December 8, 2017, headlined by Dusk Mane Necrozma GX and the debut of the Prism Star rarity via Akagi. Our PSA 10 copy of the set’s Trainer SR chase, Mars, 072/066, is currently listed at ¥25,750 — a single graded card, so once it sells it’s gone.
Prices below are our own current listings in Japanese yen, sourced from our Tokyo inventory.
Inside SM5S Ultra Sun
SM5S Ultra Sun is the fifth main numbered expansion of the Japanese Sun & Moon series, released December 8, 2017. Its enhanced-expansion twin, SM5M Ultra Moon, released the same day — a paired-release format the Sun & Moon series used repeatedly, splitting one game generation’s content across two simultaneous sets.
Internationally, Ultra Sun and Ultra Moon were unified into a single English release, Sun & Moon—Ultra Prism, which followed on February 2, 2018. Packs sold for ¥150 plus tax, five cards each, the standard configuration for this era of Japanese expansions.
The main numbered set runs to 066, with limitlesstcg’s database listing 72 distinct cards once the secret-rare tier above that number is included. Thematically, Ultra Sun leans into two things at once: its own new Necrozma fusion form (Dusk Mane) as the banner legendary, and a set of Sinnoh-region callbacks — Dialga GX among them — woven into the Trainer and Pokemon lineup alongside it. For the wider arc this set sits in, our Sun & Moon era guide covers how Ultra Sun fits between the earlier GX-era sets and what came after.
The Headline GX: Dusk Mane Necrozma
Dusk Mane Necrozma GX made its Pokemon TCG debut in SM5S Ultra Sun, printed as a secret rare at 068/066 — one slot above the set’s 66-card main numbering, which is where the Sun & Moon era placed its top chase cards. It’s the fused form of Necrozma and Solgaleo, and its presence here is exactly why Ultra Sun and Ultra Moon released as a matched pair: each set carries a different Necrozma fusion as its centerpiece.
Ultra Moon’s equivalent, Dawn Wings Necrozma GX, plays the same role in that set — different fusion, different artwork, same structural spot in the release. We break that side of the pair down in the comparison section further below.
The naming isn’t a coincidence: the video games this set draws from split the Ultra Necrozma fusion into two exclusive forms, one per version, and the TCG mirrored that split by handing each half of the card set its own fusion as the cover-star GX. That’s the throughline collectors use to keep the two sets straight — if you’re holding the daytime-colored form, you’re holding an Ultra Sun card; the nighttime-colored form belongs to Ultra Moon.
Prism Star Debuts: Akagi
SM5S Ultra Sun is where the Prism Star rarity entered the Pokemon TCG for the first time, and Akagi, printed at 059/066, is the card most associated with that debut. Prism Star cards carry a distinctive design treatment that set them apart from every rarity that came before, and Ultra Sun is where collectors point to when the mechanic’s history comes up.
As the debut print of the mechanic, Akagi tends to get referenced any time the Prism Star era of Japanese sets is discussed — it’s the starting point for a rarity family that continued to appear across the sets that followed in the Sun & Moon lineup. For anyone building a collection around “firsts” — debut mechanics, debut fusions, debut card types — SM5S Ultra Sun is a set that checks two of those boxes in a single release, which is part of why it still gets pulled into conversations about foundational Sun & Moon-era product nearly a decade later.
Sinnoh Callbacks: Dialga GX and the Mars SR
Alongside its own new Necrozma fusion content (Dusk Mane), Ultra Sun reaches back to the Sinnoh region for part of its lineup. Dialga GX, printed at 045/066 as a Double Rare, sits in the set’s main GX tier. Ultra Sun’s Pokemon lineup also includes Leafeon GX among its Sinnoh-adjacent Eeveelution content, alongside Trainer supporter cards built around Team Galactic-era characters.
The clearest example of that Trainer-card side is Mars, printed as a secret rare at 072/066 — a full-art supporter card and the anchor for anyone tracking Ultra Sun’s Trainer chase tier specifically, separate from the set’s more common Uncommon-rarity printing of the same character earlier in the base numbering. Our PSA 10 graded copy is currently listed at ¥25,750. It’s a single physical card, professionally graded — one-of-one stock, so when it sells, it’s gone.
SM5S vs SM5M: Two Halves of the Same Release
Because Ultra Sun and Ultra Moon released on the same day and merged into a single English set, it’s easy to mix the two up. They’re distinct sets with distinct headline cards, and the split runs straight down the middle of the Ultra Necrozma story.
SM5S Ultra Sun — covered in this guide — is built around Dusk Mane Necrozma GX, the Prism Star debut via Akagi, and the Dialga GX / Mars SR Sinnoh-region content detailed above.
SM5M Ultra Moon is the mirror release, headlined instead by Dawn Wings Necrozma GX, with Glaceon GX playing a comparable role on that side of the split. Our SM5M Ultra Moon pull rates and best cards guide covers that set’s own chase cards and current listings in full.
If you’re deciding which half of the pair to chase first, it usually comes down to which Necrozma fusion — and which Trainer SR — you’re after, since both sets share the same release window, pack structure, and rarity tiers.
