Installment # 21: SB-1 "Brawler" Droid 

My twenty-first creation to present to you is the SB-2 droid*. "The Brawler" is a state of the art battle droid, developed in the image of a samurai. After the separatists noticed the Samurai Trooper 1.0 that the Republic had started producing, they figured that they wanted a droid of even more damage inducing capacity. They have one problem with this first version however, and that is that they are huge (at full standing height they are 3+ minifigs tall) and very conspicuous. At the moment they are working on SB-2, the model for more covert operations.

*(Includes gigantic vibroblade katana, two boomerang throwing stars, two retractable feet saws, and a shield hat.)
