The elusive and shadowy BLACK DRAGON NINJA forces have been secretly brainwashed by DR. MINDBENDER to guard COBRA COMMANDER in case the Arashikage clan ninjas ever decide to take control of COBRA for themselves. But it's not that easy to fool the suspicious STORM SHADOW. He discovered the brainwash commands and used the Arashikage "Atsui Nami" deep mind control technique to overwrite the evil doctor's subliminal commands. Now the BLACK DRAGON NINJA forces outwardly act as if their allegiance is to COBRA COMMANDER, but in reality, they are loyal only to STORM SHADOW.
