(Lego custom minifig by ImpreSariO)
This awesome samurai minfig was custom made by ImpreSariO a very talented custom minifig builder, the inspiration for the custom minifig samurai was from samurai Jack a cartoon network TV series, whats really fantastic about the custom minifig, is the legs made from Lego bricks, see Lego actually have a range of samurai minifigs, and the legos could have been made using fabric, but this custom minifig is unique in the use of Lego bricks for this purpose, and I think you’ll agree it’s every effective is presenting a strong, bold and stylized feel to this custom minifig.
Additionally the custom minifig face is a custom decal that uses manga illustrations and is really effective, for a minifig with no other markings the face decal really expresses the personality of the minifig and the use of a four by one flat as a sword sheath is pretty cool too!

Thats not a custom face. That face is a figure in those X force sets or whatever. Go to Lego.com, and look at them.
