Legox is a Justice Chojin comprised entirely of building blocks.

A Dutch wrestler made of LEGO bricks that can transform into different shapes. However, a black brick among the blocks is the weak point. This led to his defeat in his match against Kevin Mask. He was defeated by Kevin Mask in the second match of the second round of "A" block in the Chojin Olympics: The Resurrection. He was defeated within 10 minutes and 36 seconds. Renamed Blocks in the anime for legal concerns.
