I got these Overlord figures at a convention last year. I only wish they had the overlord himself as well, but I don't think one exists. 

These are the red, blue, green and brown minions from Overlord.

Gamestop gave these out in 2009 for preording Overlord II (Xbox/PS3/PC), Overlord Minions (DS) or Overlord Dark Legend (wii). I liked but didn't finish Overlord II, disliked Overlord Minions and liked and finished Overlord Dark Legend. 

The thing about the Overlord series is that it has an art style like Fable, gameplay like Pikmin, and humerous writing like Monty Python. What's not to like? I'm so annoyed we're left with Overlord Fellowship of Evil as probably the last Overlord game. Ugg. I want some evil pikmins to control again.
