When the evil scientists at M.A.D. Sciences Organization need minions to help carry out their diabolical plots they often hire the worst warlords and criminals they can find.
Warlords and their armies often work for any cause if there is enough money (or if they are scared for their lives). They will fight brutally until their evil scientist employer stops living.
This is the brutal Warlord Abu Al-Wasta armed with pistol and in a leadership pose heroically leading his warrior band of terrorists in a nefarious plot.
