Use your LEGO bricks to build superhero characters! These simple figures just make me smile. They’re cute and simple to build, and a fun building challenge for kids.

This building project was created by my 11 year old son. He just came downstairs one day last week with three of these characters built. Then he went back up and built two more! I can’t decide which one is my favorite.

We’ve also got some fun LEGO Superhero Mosaic Building Cards, so be sure to check those out as well.

Owen built Captain America, Iron Man, the Hulk, Black Widow, and Thor. We’ve got building instructions for building Captain America, and then we’ll show you pictures of the rest. Once kids get the basic pattern down, it should be easy to customize the design to build each of the characters.

Lego Marvel Captain America, Iron Man, and Thor

How to Build Captain America

Step 1: Find the pieces shown for building the head.

Step 2: Grab a 2 x 3 tan plate and add a 1 x 3 tan brick and two 1 x 1 tan plates. A 1 x 1 red round plate would probably be better for the mouth, but I guess all Owen could find was a red flower, ha. Use whichever one you want!

Step 3: Add three 1 x 1 tan bricks with a stud on the side. Add the eyes and a 1 x 1 tan slope for the nose. Another option is to use a 1 x 2 tan slope brick instead of the 1 x 1 slope and the 1 x 1 brick.

Step 4: Add a 1 x 3 brown plate for hair. Then find a 2 x 2 brown plate, a 1 x 2 brown plate, a 1 x 2 brown slope, and a 1 x 1 brown slope.

Step 5: Attach the brown plates to the head and then add the slopes.

Step 6: Gather the bricks shown for building Captain America’s body.

Step 7: Place two 1 x 3 brown plates (or a 2 x 3 brown plate) on top of a 2 x 3 blue plate. Then add a 1 x 3 blue brick, two 1 x 1 white bricks, and a 1 x 1 red brick in the center.

Step 8: Add three 1 x 1 blue bricks with a stud on the side. Pay close attention to which way the studs face in the picture.

Step 9: Turn the body around to the back and add two 1 x 1 blue bricks and a 1 x 1 blue brick with a stud on the side.

Step 10: Find two 1 x 2 blue bricks and a 1 x 2 blue plate for building the legs.

Step 11: Add the legs as shown. Add a 1 x 1 white round tile on his chest.

Step 12: Build the arms. Each arm is a 1 x 2 blue curved slope and a 1 x 1 blue plate with light attachment. Before adding the arms, place a 1 x 1 red plate with a clip on the side of the body.

**There was disagreement between the brothers in our family about whether or not the plates with a clip looked good or not. I thought they did. If you prefer, just add 1 x 1 red plates without the clip. Or whatever.

Attach the arms, and Captain America is complete!

Build his shield with a 4 x 4 white round plate, a 2 x 2 red round plate, and a 1 x 1 blue round plate.

Now let’s build some more!

Iron Man

Iron man is very similar to Captain America. His eyes are 1 x 1 translucent light blue round plates.


Hulk’s body is 4 studs wide instead of 3 for the other characters. His head is on top of a 2 x 2 plate with one stud on top. This centers it on the 2 x 4 body and also allows the head to turn.

Black Widow

There was discussion in our household about whether Black Widow’s hair was the right color or not. As a red-headed person, I totally understand. I can remember as a kid coloring pictures of myself with a brown crayon because my hair wasn’t crayon red! And it wasn’t crayon orange either! So you can make Black Widow’s hair any color you want.

Her hands are clips so that she can hold a gun.


I think Thor turned out really great! He is wearing a red cape. The hammer is attached to both the top and bottom of his hand.

Here’s a picture that shows the hammer better. Attach the top of the hammer to the top of his hand and the bottom to the underside of his hand. The hands are 1 x 1 tan plates with a light attachment.
