The Real Question Is: Why Are You Putting These Two Things Together?
My old, dusty, broken, and cheap friend, Mega Bloks, why have you returned to public discourse? If you have found yourself here to ask if these two toys, LEGO® and Mega Bloks, can fit together, the answer is yes; these toys are compatible.
Please Don’t Put Them Together
Let’s be honest; it’s an unholy match. Nothing bad will happen but Mega Bloks are pretty…meh…mediocre at best. Mega Bloks were the original knock-off LEGO®. I don’t think any real LEGO® fan will forgive them for the stuff they tried to pull copying the one true brick.
Okay, but enough roasting. You might be putting them together because you have a creation you are working on putting together. On my TikTok page, many people comment that the Halo Mega Bloks sets were elite. However, I won’t touch the stuff with a ten-foot pole.
It’s not that I don’t like the design. The quality is horrific. They disintegrate just sitting in your LEGO® bins.
Let’s Go Over The Truth Of Mega Bloks
LEGO® spent nine years trying, unsuccessfully, to sue Mega Bloks for its infringement on the design of its bricks, and the final ruling came in November 2005. The Supreme Court of Canada allowed Mega Bloks to continue its functions (and in September 2010 the European Court of Justice ruled the classic 8-stud LEGO® brick design couldn’t be a trademark either) — however, Mega Bloks changed after that time period and were built…oddly. I think, most likely, to avoid further legal challenges. The quality of proto-Mega Bloks was awful after that period. The sizing of studs and holes wasn’t right. Minifigs fell apart and couldn’t stand. When you tried to piece bricks together, they popped apart.
The fact that these bricks are even remotely compatible is a testament to the fact that Mega Bloks is a copy of LEGO®. While Mega Bloks product has improved, its LEGO® compatible legacy is like Elden Ring: forever tarnished!
Mega Bloks Lost Pokémon — And LEGO® Took It
Nobody saw this one coming. For years, Mega Bloks (rebranded to MEGA Construx, then just MEGA under Mattel) held the Pokémon construction toy license. They pumped out about 150 sets featuring roughly 130 different Pokémon since 2017.
Then LEGO® came knocking. In March 2025, LEGO® announced a multi-year partnership with The Pokémon Company, and Mattel confirmed that MEGA would stop supplying Pokémon products as of December 2025. The first LEGO® Pokémon sets hit shelves around March 2026, from the 587-piece 72151 Eevee at $59.99 to the 6,838-piece 72153 Venusaur, Charizard and Blastoise at $649.99, and a second wave followed in August 2026. MEGA’s biggest license just walked out the door and into the arms of the one true brick. If that doesn’t sum up the Mega Bloks experience, I don’t know what does.
If Mega Bloks Is Still Around, Where Can I Purchase Them To Combine With LEGO®…For Science?
Mega Bloks is notorious for fumbling the bag. They are still functioning and around — barely. Mattel launched a new building line in 2025 called “Mattel Brick Shop,” focusing on Hot Wheels and car-brand building sets like Lamborghini, Aston Martin and Toyota. Whether that’s a fresh start or just Mega Bloks in a new outfit remains to be seen. Their distribution and marketing are nowhere near where they used to be. Looking for Mega Bloks is harder than looking for retired LEGO® sets.
If you are a Halo fan, Mattel Brick Shop has the HYL44 Microsoft Xbox Collector Building Set going on sale from 16 October 2026, 3,509 pieces at roughly $330 (€350), with a 935-piece Halo Warthog kit landing alongside it for roughly $76. The press says Brick Shop uses the same stud system as LEGO®, so the bricks should fit together, though I have not put that to the test myself.
You have not heard about it. The brand recognition and spread is not there. If you need Mega Bloks, the best place to look would be Walmart or eBay. It is silly because the demand is still there, hence the prices on eBay, but Mega Bloks refuses to distribute their toys more effectively.
Frequently Asked Questions
Yes, Mega Bloks (now branded as MEGA under Mattel) are physically compatible with standard LEGO® bricks. The stud dimensions are similar enough that pieces can connect. However, the fit is often looser and the plastic quality is noticeably lower than genuine LEGO® bricks.
Mega Bloks use a lower-grade ABS plastic compared to LEGO®. This results in less precise stud tolerances, weaker clutch power, and bricks that can warp or degrade over time. Many collectors report that older Mega Bloks pieces disintegrate just sitting in storage bins.
Yes. LEGO® (through its parent company Kirkbi AG) sued Mega Bloks over trademark claims related to the brick’s stud design. In November 2005, the Supreme Court of Canada ruled unanimously in favor of Mega Bloks, finding that purely functional design features like the interlocking stud pattern cannot be trademarked.
No. Mattel confirmed that MEGA stopped supplying Pokémon products as of December 2025. LEGO® now holds the Pokémon construction toy license and began releasing LEGO® Pokémon sets in 2026.
Mega Bloks (MEGA) sets can still be found at Walmart, Target, and eBay, though availability has shrunk significantly. Mattel also launched the “Mattel Brick Shop” brand in 2025 with building sets featuring Hot Wheels and other Mattel properties.
