Astro has. Skunk Kusai Slippery (Canadian dub), Sirius (French dub) An enigmatic thief and mob leader in Tokyo, known for his blue skin and bloodhound eyes. In the beginning of the series, he works with Walpurgis in order to copy Astro's design blueprints. Skunk was assigned to teach Atlas, but, after becoming frustrated with him, the majority of the teaching was done by Livian. After Skunk set up Astro and Atlas's first battle, Walpurgis destroyed Livian, and Skunk just barely got away from Atlas's hysterical backlash. Skunk went to Tokyo and started up a gang, whom briefly used the adult Atlas to commit several robberies when Atlas returned. Throughout the rest of the series, Skunk utilizes various robots for his own doings, most famously in the episode "The Light Ray Robot". He develops a strong hate for Astro because of the boy's constant interference with Skunk's work. At times, the latter tries to destroy or taunt him. He is voiced by Seizō Katō and Jay Rath (American version). Tobio Tenma Toby Boynton (American dub) A nine-year-old boy who is the son of Doctor Tenma who was fatally wounded in a car accident.

He is voiced by Mari Shimizu, Patricia Kugler Whitely (American version) and Steven Bednarski (Canadian version).
