Blackie Young is a Junior High School gangster leader that hates robots. He and his men always wear black masks and black suits. They destroy and steal from robots, but never from women, mainly because Blackie's mother was killed by robots and he has a personal vendetta against them all.
In the 1980s episode Blackie Young, Astro finds out that Blackie's mother is actually a nurse robot named Aurora (Rosaline in Japanese). Aurora wanted to adopt Blackie when he was little but the robot laws don't allow it. When she went to a robot rights protest, she was destroyed.
Blackie reconciles his mistakes and Aurora takes him back with the unconditional love only a mother can provide to her son.
