After moving to South Korea and buying two new sets, my minifig collection has gone from around 400 to exactly 4. Here is what I've done with them:
This is the Librarian. He's a former apprentice of the Tek Wizard viewtopic.php?f=17&t=11232&hilit=tek+wizard
The Librarian is obsessed with finding the secrets of the universe and storing them in his digital library.He's seen here guarding top secret information with an auto turret he built. He wields a pistol, fitted with a large silencer, which he uses to quiet those who would either spill his secrets or talk too loudly in his library.
Here's a space ninja with his chopper. Equipped with several blades and launching shirukens, he can use it to devastating effect in aerial melee combat.
This is Angry Joe. He was once a professional boxer, but through countless the battles he's fought and survived over the years, his body was destroyed piece by piece. Each part was replaced with cybernetic components, until the only original part of him remaining was his anger and hatred for others.
Here he is with his hovercraft. The ship's fists are controlled by his motions. He's KO'd almost as many ships as he has opponents in the ring.
Lastly, here is Lord Zandar, a space templar, dedicated to fighting an intergalactic crusade against tyranny.
What's a knight without his trusty steed? In this case, Lord Zander pilots an armored deathcart. Equipped with a pair of machine guns, grenade launchers and missiles, it's a lethal combination of speed and firepower.
