John (The Custodians)
From Tardis Wiki, the free Doctor Who reference
John was the senior vice-president of Green Room Entertainment, the company which created the virtual reality detention facilities. He worked with the Department to use the last Etydion to broadcast a telepathic signal which would take control of the children who were playing the Little Green Men game. When it was revealed that the children were also mutating into Etydions, John blackmailed Drake, asking for fifty million credits to end the transmission. However, his attempts to do so failed as the Etydion was long under his control, and Drake told John that he would be sent to prison. (K9TV: The Custodians)
