James Ellison is the head of security for ZeiraCorp and a former FBI agent. He was originally tasked with bringing Sarah Connor to justice for the murder of Miles Dyson and the bombing of Cyberdyne headquarters in the mid-90's, as well as the 1999 armed bank robbery in which several safety deposit boxes were emptied and significant property damage occurred. Since then, Ellison has seen incontrovertible evidence about the rise of Terminators, and has realized that Sarah is telling the truth and thus not actually insane.
