The least known alter of the system. No information exists of his origins, no information of his motive. All there is to know is that whenever this alter fronts, there is an enormous amount of carnage that happens afterwards.
There are moments where switches occur, switches that Steven or Marc can't take responsibility for. It is believed that these moments are when Jake appears, to protect the other two from danger in an excessively violent fashion. This alter doesn't seem to have moral restraints to his actions, leaving behind destruction that Steven or Marc cannot explain.
This is what we are shown when he appears to execute the villian; a curious gaze towards Harrow who is trapped helplessly in the car. And when his death comes, Jake grins menacingly.
There is much to be discovered about his character, especially his thoughts on the other two alters.
