I cracked open a full sealed display of 12 Space Marine Heroes Series 1 Ultramarines in this video, going box by box, calling out duplicates and reveals as I went. The video is the unboxing in full. Below is the context that didn’t fit into the runtime: the history of the range, what’s actually inside the boxes, and why sealed Series 1 displays are getting harder to find in 2026.
What Space Marine Heroes Actually Is
Space Marine Heroes Series 1 launched in September 2017 as a Japan-exclusive product. Twelve push-fit Ultramarine Tactical Marines, each in a sealed blind box with a character card, randomly distributed across a display. The sculpts came out of Eastern manufacturing rather than the UK Citadel facility, which is why the sprue webs are thinner and the gates smaller than standard GW kits, with frames that look closer to a model kit runner.
The Japan edition shipped with thirteen sculpts: ten standard Tactical Marines, two secret variants, and Brother Toriad as a chase. Each model appeared twice per display, so a full sealed display gave you every sculpt with one guaranteed duplicate.
The Rest of the World release (which is what most of us got) trimmed the lineup to nine sculpts and reintroduced rarity through a 1:36 chase ratio on Brother-Captain Thassarius. Four of the Japan-exclusive sculpts (Brother Calistus with the flamer, Brother Aethor running with a combat knife, Brother Dolor with the auspex, and Brother Toriad with the heavy bolter) never made it into the ROW boxes. Those four sculpts only ever shipped in Japan-edition displays.
Inside the Boxes
The full Series 1 lineup is Brother-Captain Thassarius, Brother Sergeant Sevastus, Brother Titus, Brother Remus, Brother Gaiun, Brother Vanial, Brother Garus, Brother Castor, and Brother Promethor across the standard run, plus Calistus, Aethor, Dolor, and Toriad if you’re opening Japan-edition boxes.
Each sculpt has a unique dynamic pose, a sculpted base, and both a bare-headed and helmeted option. There are no chapter markings on the models themselves. The Ultramarine artwork on the box is decorative. They build clean as any chapter you want to paint them as, which is part of why Series 1 has stayed popular for kitbashes long after the line stopped being current.
The character cards are a nice touch. Each comes with a short bio, a name, and stat block context that frames the model as an individual rather than a generic Tactical Marine. For people who run narrative-driven kill teams or paint up characters with specific army stories in mind, the cards add a small piece of identity to each pull.
Why Sealed Series 1 Is Harder to Find Now
Games Workshop rebranded the entire range as Warhammer Heroes in 2025. The Space Marine Heroes name is gone from current product. Series 1 boxes stopped getting reprints years before that, since the line moved on to Series 2 and beyond, but the rebrand cut off the last residual stock supply. Every sealed Series 1 display in circulation now is whatever was sitting on shelves or in warehouses before the cutover.
Secondary prices reflect this. Sealed Japan-edition displays in particular have become collector-grade items. ROW displays are easier to find but are starting to climb. If you’re hunting one of the missing Japan-exclusive sculpts specifically, eBay is the only realistic option, and the prices are not what they were three years ago.
What I’d Do With Them
Series 1 sculpts are excellent kitbash fodder. The bodies are pure push-fit Tactical Marine, but the unique poses, the dynamic action stances, and the absence of chapter markings make them easy to convert into characters for any Space Marines chapter. I’ve seen people repaint them as Salamanders, Imperial Fists, Crimson Fists, and Black Templars with shoulder pad swaps and minor weapon conversions. The character cards make them work as named Lieutenants, Veteran Sergeants, or campaign protagonists in narrative play.
For the Ultramarines player who wants to keep them stock, a full Series 1 display gives you a Tactical Squad’s worth of distinctive named characters, each with established lore and a card. Each Series 1 sculpt has its own pose, weapon, and named identity, which changes how they read on the table compared to a standard Tactical Marine kit, particularly in narrative play.
If you want a more recent hobby companion to this format, the Heroes of the First Company box uses similar single-character packaging with Terminator-scale models and is a useful comparison point for anyone deciding which Heroes-line product is worth chasing in 2026.
Watch the Video
The full unboxing is the video at the top of this post. Twelve sealed boxes, one by one, with the running tally of who I pulled and which sculpts I ended up doubling up on. Whether the chase came out of the display, you’ll have to watch and find out.
