The Verdict
The Short Version: A Two-Sided Battle Set That Actually Delivers on Play Value
Most LEGO superhero sets give you one hero, one villain, and a lot of empty space. This one gives you two fully articulated mechs and four minifigures. That’s the headline. At 437 pieces, it’s not a massive build, but what’s here is smartly designed for actual play — not just shelf display.
What You Actually Get
Open the box and you’ll find four numbered bags, two instruction booklets (one for each mech, so two kids can build simultaneously), and a sticker sheet. The minifigure lineup is the real draw: Superman with his classic red and blue suit, Lex Luthor in his green and purple warsuit, Mercy Graves with a printed torso, and a buildable Superbot that’s a fun bonus.
The Superman mech stands about 5 inches tall with posable arms, legs, and a cockpit that opens from the chest. Lex’s mech is bulkier — closer to 6 inches — and features a Kryptonite power function that fires a translucent green stud when you press the lever on its back. That’s the standout play feature. Pull the lever, launch the Kryptonite, watch Superman’s mech take a hit.
Build Quality and Real-World Use
LEGO’s quality control is consistent here. The bricks click together with the satisfying precision you expect, and the Kryptonite mechanism works smoothly — no jamming, no fragile pieces snapping off. The articulated joints on both mechs hold their poses well. I’ve had cheaper mech sets where the arms flop after a week; that’s not an issue here.
The minifigures are where this set shines. Superman’s cape is the proper cloth version, not the stiff plastic one. Lex’s warsuit has molded armor details that look sharp. Mercy Graves is a welcome inclusion — she rarely appears in LEGO form, so collectors will want this set just for her.
What Buyers Consistently Praise
The 4.7-star average across 235 ratings isn’t inflated. Reviewers consistently mention the same things. One parent noted, “My 7-year-old and 5-year-old each built one mech at the same time — that alone was worth the price.” Another buyer highlighted the Kryptonite launcher: “My son has replayed the battle scene from the movie at least fifty times. The launcher is his favorite part.”
Collectors are also happy. Multiple reviews mention the minifigure selection as the primary reason to buy, with one writing, “Mercy Graves alone makes this worth it. She’s never been in a set this affordable.”
Where It Falls Short
The biggest imbalance is the mechs themselves. Superman’s is visibly smaller and less detailed — fewer armor panels, simpler leg construction, no weapon beyond a basic fist. Lex’s mech gets the Kryptonite launcher, the bulkier frame, and the more imposing silhouette. Thematically it makes sense (Lex needs the advantage), but kids will notice Superman got the short end of the stick.
The sticker sheet is also a minor annoyance. Several pieces — including Lex’s chest emblem and the control panels — require stickers for the finished look. At this price point, printed pieces would have been nicer.
And if you’re an adult builder expecting a challenge, manage expectations. This is a 30-minute build, tops. It’s designed for ages 8 and up, and it hits that target perfectly. For experienced builders, it’s more of a quick fix than a satisfying project.
Who Should Buy This
- Parents of kids 6-10: This is the sweet spot. Two mechs means siblings can play together without conflict. The Kryptonite launcher is robust enough to survive enthusiastic use.
- LEGO DC collectors: You’re buying for Mercy Graves and the Superbot. The mechs are a bonus.
- Gift-givers: If you need a birthday present that doesn’t require assembly supervision, this fits the bill.
Skip it if you’re an adult collector wanting a display-worthy set or a complex build. This is a toy first, a display piece second.
FAQ
Q: Is the Kryptonite launcher safe for younger kids? A: Yes. It fires a standard LEGO stud, not a projectile. It’s the same mechanism used in many LEGO sets. No choking hazard beyond the standard small-parts warning.
Q: Does Superman’s mech have any weapons? A: No. It’s fists-only. The play value comes from the mech’s maneuverability and the Kryptonite battle dynamic. If you want a weaponized Superman mech, you’d need to modify it or buy a different set.
Q: Can the mechs combine into a larger figure? A: No, they’re separate builds. But they can be posed facing each other in a battle stance, which looks great on a shelf.
The Verdict
This is one of the better LEGO DC sets in recent memory. It’s not the biggest, not the most complex, and not the most display-worthy — but it nails what a toy should be: fun, durable, and engaging. The minifigure selection is excellent, the Kryptonite mechanic is genuinely clever, and the dual-mech design means two kids can play at once.
Buy it if you want a solid, play-focused LEGO DC set with great minifigures and real interactive value.
Skip it if you’re a serious builder looking for a challenge or a collector wanting a centerpiece display model.
