- —McGrath speaking to Jodie about her comatose state
General McGrath is the secondary antagonist in Beyond: Two Souls. He is the lead Army officer assigned to oversee the DPA's Infraworld research.
General McGrath was born on 27th November, 1949, he is a four-star general in the United States Army who serves as the Director of the CIA, McGrath has been responsible for funding the Infraworld Condenser project, providing that it be used to seek both mineral wealth and military options for the United States. He is responsible for authorizing a mission to Kazirstan following the discovery of a second condenser and intrusion into what he sees as American property.
Ruthless and single-minded, McGrath is prepared to utilize captured Entities as soldiers in warfare, ensuring that the U.S. remains the dominant super power with this new tactical advantage. He is ultimately unwilling to let Jodie leave following the completion of her mission and so has her captured. He tells Jodie that they cannot let her go for fear of her powers, but nor can he kill her since the Infraworld would give her further access to them, so he has Jodie drugged in the same manner as her mother, revealing that he was the one to authorize her condition in that way.
Through the help of Aiden, Cole and Ryan, Jodie is freed. At that moment, the deranged Nathan deactivates the containment field, in an attempt to merge the Real World with the Infraworld, allowing the monstrous entities access to the CIA base. McGrath sees that Jodie has escaped and requests her to protect him, but Jodie refuses to do so, stating that he deserves to be killed for all of the things that he has done, although Jodie admits that even the Infraworld doesn't deserve to be a home to someone like him either. He then orders Ryan to save him, but the angry Ryan refuses to and instead punches the general down suggesting that Ryan agrees with Jodie that he doesn't deserve to be saved for all that he has done. Ryan then resigns as a result. His ultimate fate is unknown but he is seen as a phantom in the Infraworld, suggesting he might have been killed or he escaped the CIA base.
