In the Star Trek universe, pretty much anyone who hasn't joined the United Federation of Planets is a bad guy. (Sound familiar?)
Here are Lego Hacker's "micro" versions of some of Star Trek's most notorious bad guys. In one image, a Klingon Bird of Prey circles the Ty'Gokor orbital station. In another, a slew of Jem'Hadar warships emerges from the wormhole outside the starbase known as Deep Space Nine / Terok Nor, while Cardassian Galor and Keldon class starships patrol nearby.
The design constraint of conveying a structure's essence with a minimum number of bricks can inspire inventive ways to re-use Lego pieces. For example, Lego Hacker bent two pieces from the bow of a Viking ballista to make the circular habitat ring of Deep Space Nine.
