Robo Samurai is one of many of my characters who I've had the opportunity to create a really cool back story for which basically involves a trio of robotics designers, who just happen to be all part cybernetic themselves, playing God and each creating their own races of robots on their own planets they decided to colonize with their creations. Of course since doing such things has its consequences, some of these robots stayed good, while others turned bad ... R.S. here is one of the bad ones.
Yes, I know samurai don't use nunchucks, and I knew someone was going to mention it, but I did it anyway for precisely the reason you stated Star. A bad ass martial arts warrior robot can use any weapons he damn well pleases.
a samurai that uses nunchaks? hmm. i guess if youre a killing machine it doesnt matter if you cross cultures. cool, but i'll bet my Kumatae would give him a run for his money.
