Robert Stockman was the founder and director of genetic research institute StockGen. Stockman was ambitious and wanted to train his son Baxter to be the perfect successor as the head of the institute, and so he began to train him rigorously in the use of his intellect from childhood on, with the premise of: "When you think, you can turn anything into a win - And winning is what life is all about!".
However, in his lessons, Stockman was too careless and strict with his son. Although he taught him to use his mind with daily chess, his merciless attitude aroused a silent resentment in Baxter's heart. Nonetheless, Baxter followed his father's lessons rigorously and waited until he finally was an adult before he begin his revenge. In a carefully planned sting, he expropriated his own father, personally taking control of StockGen, thus dismissing the older Stockman into forced retirement.
Originally, Baxter Stockman's father was never given a name, and Bobby Curnow explains that his name in the Baxter one-shot issue's script was simply "Baxter's Dad." After a comment on the Technodrome forums suggested the name "Robert Stockman," Curnow accepted it as the character's official name. But the character has never (yet) been called "Robert Stockman" in published comics.
