Dr. Julius No is a rich nuclear scientist who made several appearances in the James Bond Jr. cartoon and Marvel comic series.
Dr. No is an agent of the crime organization SCUM and regular opponent of James Bond. is first seen kidnapping Professor Frost, a scientist involved in cryogenics. Dr. No later attempted to steal all the water reserves in the Middle-East. Later he kidnaps Lily Mai, a new student at Warfield Academy, in an attempt to settle and old score of his with Macau's chief criminal organization, the Raven Triad.
He later sends his Ninjas to Japan to steal a prized sword in his plan to learn of the sword's powerful material origin and uses it to create a powerful weapon for his arsenal. Dr. No later teams up with Oddjob using purple roses to hypnotize people. Dr. No later plots to build an impenetrable government airship known as "the Vulture".
The appearance of the character was drastically altered for the series: his accent, costume and mustache are quite exaggeratedly Asian and many of his schemes involve ninjas, samurai swords and the like. His skin was also rendered bright green - perhaps a callback to his seeming death by radioactivity, but also not an uncommon treatment for Asian villains to receive in animation at the time.
