The Colress Machine first appeared in Flying Type and Innocent Scientist, where Colress was shown using it to control Genesect and have it attack Blake and Looker. In Unforgettable Memories, Colress reported favorable results from his first test of his invention. Later, in PS537, Whitley's mother revealed that Colress's machine was capable of controlling Pokémon.
In Innocent Scientist, it was revealed that Colress had already begun the machine's development two years earlier, but some members of Team Plasma had opposed his work, as it ran contrary to their beliefs. As such, they had secretly developed a method to stop the machine's influence on Pokémon, and the memory card containing that data had been entrusted to a twelve-year-old girl.
