Questions
Are these official LEGO sets?
No. They are free fan-made MOCs designed from standard LEGO bricks and plates, with their own step-by-step instructions and parts lists.
Can I ask for my favourite superhero?
Yes. Type the hero into "Ask for any build" and Mister Blocks designs a brick-built version with instructions in a few minutes.
