Dr. Vector is a major ally in the game Jack Dimensional. It is his first, and only, appearance, so he hasn't changed at all. Years before the events of the game, he created a strange simulator, called the Dimensional Vector. It is a strange world that simulates environments in the shape of planets.
Dr. Vector is very nice. There is but one person he despises: Dragoroth. Dragoroth took over the Dimensional Vector, turning the whole thing againts him. He and his brother, Professor Uranium, built a small camp on one of the moons. The name is currently unknown.
