Competitron was best known for the computer game Riddle of the Minotaur, the brainchild of Edward Nygma. However, while Minotaur made millions of dollars for the company, Nygma was denied royalties on his game, and fired when he tried to sue for them. Mockridge brushed him off, claiming that Competitron's strength lay in its "corporate attitude", rather than its products. In the incident's aftermath, the deal went through and Competitron's operations were moved to Gotham. Mockridge himself made ten million dollars on the sale, but was left in constant fear that Nygma might come back for him.
