LEGO Iron Man Hall of Armor 76125 vs Detroit Steel Strikes 76077: Which Marvel Sealed Pick
Last updated: 5 May 2026
LEGO Iron Man Hall of Armor 76125 vs Detroit Steel Strikes 76077: Which Marvel Sealed Pick
The LEGO Marvel Iron Man Hall of Armor 76125 is a 524-piece display set with four exclusive Iron Man armour variants in a modular bay diorama. The Iron Man: Detroit Steel Strikes 76077 is a 377-piece mech-fight set with Justin Hammer, Iron Man and Agent Coulson alongside the Lola hover-car build. Both retired, both figure-led purchases, and both at very different stages of their post-retirement market trajectory. We hold sealed verified copies of both at 76125 for £139.99 and 76077 for £155.99, factory-sealed and inspected in our Yorkshire warehouse before despatch.
This guide is for the UK Marvel collector deciding between two retired Iron Man-themed sets. We cover what each set actually delivers, why neither is bought for the build, the figure-led purchase rationale that drives both, and which one earns the shelf space.
- 76125 has 4 exclusive Iron Man armour variants (Mk 1, Mk 5, Mk 41, Mk 50) plus 2 Outriders, retired July 2021
- 76077 has the first ever Justin Hammer minifigure plus the second Agent Coulson, retired December 2018
- 76125’s modular Hall of Armor diorama displays four armours; the larger Endgame hangar requires the 76167 Iron Man Armoury sequel set
- 76077’s Lola car is the headline build, not Detroit Steel itself

LEGO Iron Man Hall of Armor 76125 at a glance
The 76125 was released alongside the original Avengers Endgame wave in spring 2019. The headline value was the four exclusive Iron Man armour variants in one box: Mk 1 (sh0565, the Cave armour from the first film), Mk 5 (sh0566, the briefcase armour), Mk 41 (sh0567, the Bones armour from Iron Man 3), and Mk 50 (sh0496, the Infinity War nano-suit). Plus two Outriders (sh0505) for the attacking-force play element.
The diorama is built as four modular bays that connect into a horseshoe, line, or curve configuration. Each bay houses one armour variant and includes a rotating podium plus a small Tony Stark desk with monitors. The build is repetitive because the bays are essentially the same module four times over.
The 76125 specifically does NOT include Iron Patriot, Cosmic Iron Man or Pepper Potts in Rescue armour. Those figures are in the 2020 sequel set 76167 Iron Man Armoury, which connects to the 76125 to form a larger Hall. If you want the full Endgame wall, both sets pair up.
LEGO Iron Man: Detroit Steel Strikes 76077 at a glance
The 76077 was a Captain America Civil War-era Marvel set that flew under the radar at release in 2017 and has since become a quiet completionist target. The headline value is character firsts: this is the first ever LEGO Justin Hammer minifigure (sh0367), and only the second LEGO Agent Coulson minifigure (sh0369) since the 2008 first-appearance figure.
Three figures: Justin Hammer in his Hammer Industries suit, Invincible Iron Man (sh0368, an exclusive variant), and Agent Coulson in dark suit. The Detroit Steel mech is a built model rather than a minifigure, piloted by an unnamed unprinted figure.
The Lola hover-car is widely cited as the best LEGO has produced at minifigure scale. Sleek curves, printed detail, and a transformation between car and hover modes. Most reviewers point to the Lola, not the Detroit Steel mech, as the reason this set holds value.
How does the build experience compare?
These are short builds. The 76125 finishes in around 1.5 to 2 hours total, with the four bay modules built in sequence. Once the first bay is done, the next three follow the same pattern, which is why "repetitive" is the most-cited build criticism. The Tony desk and monitors are the most varied moment in the build.
The 76077 finishes in around 45 to 60 minutes. The Lola car takes most of the parts budget, the Detroit Steel mech the rest, and the figures slot in last. The Lola is the build moment that makes the set feel worth buying; the mech is the disappointment most reviewers flag.
Neither set is going to satisfy a builder who wants engineering depth. Both are picked up for the figures and finished as quick afternoon projects.
How do they display together?
They do not really share a shelf. The 76125 is a horizontal four-bay diorama that wants 40-50 cm of front-facing display space, with the four bays facing forward and the figures visible from the standard viewing angle. Pair it with the 76167 Iron Man Armoury for the full Endgame wall.
The 76077 is a smaller diorama with the Detroit Steel mech as the centrepiece and the Lola posed beside it. It needs around 30 cm of shelf space and reads best from the side rather than head-on, so the mech and car are both visible.
If you collect Marvel character firsts, the 76077 sits next to your other Coulson and Hammer scenes. If you collect Iron Man armour variants, the 76125 sits with the Iron Man Armoury and any other armour-pack sets you have.
Side-by-side comparison
| Factor | 76125 Hall of Armor | 76077 Detroit Steel |
|---|---|---|
| Pieces | 524 | 377 |
| Released | March 2019 | January 2017 |
| Retired | July 2021 | December 2018 |
| Theme line | Avengers Endgame | Civil War-era tie-in |
| Minifigures | 6 (4 Iron Man, 2 Outriders) | 3 (Hammer, Iron Man, Coulson) |
| Headline figure value | 4 Iron Man variants exclusive | First-ever Hammer, second Coulson |
| Headline build value | Modular Hall diorama | Lola hover-car |
| Build time | 1.5 to 2 hours | 45 to 60 minutes |
| UK sealed (May 2026) | £139.99 at BuyMyBricks | £155.99 at BuyMyBricks |
Choose the 76125 if you collect Iron Man armour variants and want Mk 1, Mk 5, Mk 41 and Mk 50 in one box, the modular Hall of Armor diorama is the display approach you want, or you intend to pair it with the 76167 sequel set for the full Endgame wall. The Outriders are play-element extras, not the reason you buy.
Choose the 76077 if you collect Marvel character firsts (Justin Hammer makes his only LEGO appearance in this set), the Lola hover-car is the build that interests you, or you want a small Civil War-era diorama that does not duplicate any of the larger Civil War sets. The Detroit Steel mech is the secondary build, not the headline.
If the budget allows both, they do not duplicate. Different Marvel eras, different figure rosters, different display approaches.

Why does sealed matter for these two sets?
For the 76125, the four exclusive Iron Man armour figures are the entire reason the set holds value. Standalone replacement on BrickLink for the Mk 1 (sh0565), Mk 5 (sh0566), Mk 41 (sh0567) and Mk 50 (sh0496) variants together runs £60 to £90 plus shipping, which is a significant fraction of the sealed-set price. Used 76125 listings without the full figure roster should be discounted heavily. The two Outriders are also exclusive to this era and not interchangeable with later Outrider sets.
For the 76077, Justin Hammer (sh0367) is the single most important figure: it is his only LEGO minifigure ever produced, and standalone replacement on BrickLink runs £25 to £45. Agent Coulson (sh0369) is the second-rarest LEGO Coulson minifigure ever made and runs £15 to £30 standalone. A used 76077 without those two figures is essentially worthless to a Marvel collector. The Lola car uses sticker decals on the wheel arches that cannot be re-flatted once applied, so a sealed copy keeps the build options open.
This is what BuyMyBricks does. We hold sealed verified copies, inspected for original factory seals and intact tape on every flap before listing. 76125 sealed at £139.99. 76077 sealed at £155.99.
Where to buy these sealed in the UK
- BuyMyBricks. Both sets sealed and verified, despatched from our Yorkshire warehouse with tracked UK shipping in 1 to 2 working days, 30-day returns. UK-registered specialist, not a marketplace seller.
- eBay UK. Both sets appear regularly. Verify seller feedback (90 plus, 99 percent positive). For the 76125, demand a clear photo of all four sealed Iron Man figure bags inside the box. For the 76077, demand confirmation Justin Hammer and Agent Coulson are still in original sealed bags.
- BrickLink. European sellers carry both sets. Factor 5 to 15 working days for international post and customs handling.
- Amazon UK. Third-party listings only on both sets, typically priced higher than the UK specialist market.
For a UK buyer in 2026, BuyMyBricks is the obvious place to start. We are a UK-registered specialist, not a marketplace seller. Every sealed copy is inspected for original factory seal stickers, no re-taping, no edge creasing, and a set-number match against the box.
What other builders make of the 76125 and the 76077
Don’t just take our word for it
For the 76125, Brick Insights aggregates reviewer scores around 83 out of 100. Reviewers consistently praise the four-figure pack as the headline value, the modular bay system as a flexible diorama solution, and the rotating podium with Tony Stark’s desk as a focal point that lifts the build. The honest criticisms are that the bay build is essentially repetitive (the same module four times), the sticker legibility on the desk monitors is poor, and the Igor mech is described as out-of-scale and clashes visually with the rest of the diorama. Pair with 76167 if you want the full Endgame wall.
For the 76077, Brick Insights aggregates reviewer scores around 78 out of 100, with Jay’s Brick Blog scoring it 4 out of 5. The Lola hover-car is widely called one of the best LEGO has produced at minifigure scale, and the first-ever Justin Hammer plus the second-ever Agent Coulson make this a Marvel-completionist target. The criticisms are that the Detroit Steel mech itself is the weak build (skeletal, undersized clawed hands, small saw arm), and that splitting the parts budget across car-and-mech meant neither is its strongest possible version.
Neither criticism set is a deal-breaker. They are buyer expectations a guide should set straight before you open the box.

Does LEGO 76125 include Iron Patriot or Pepper Potts?

Three minifigures: Justin Hammer (sh0367, the first-ever LEGO Justin Hammer), Invincible Iron Man (sh0368, exclusive variant), and Agent Coulson (sh0369, only the second LEGO Coulson since the 2008 first-appearance figure).
Is the LEGO 76077 Lola car worth the set price alone?

How long does the LEGO 76125 take to build?
Around 1.5 to 2 hours total. The four bay modules build in sequence and the build is acknowledged as repetitive because each bay uses essentially the same module pattern.
