I just got hold of the first half of season 1 The Pretender. Oh the 90's nostalgia.
That was a crazy ass weird show (that was generally entertaining) and everyone only had one name.
Jarod the odd genius raised by the mysterious Centre because he has the uncanny ability to assume any identity, the skills that go with it, and analyse a situation through from their viewpoint. Breaks out of the Center in the first episode and goes on the run, taking identities and doing good and punishing bad-guy-of the week in ironic ways. Always leaving just one step ahead of the team chasing him.
Ms Parker, the femme fatale leading the group hunting down Jarod.
Sydney, the Doctor who raised him and while sympathetic is also one of those tasked with hunting Jarod down after he escapes.
Broots, the amiable but cowardly tech guy who also is part of the team hunting Jarod down.
Seriously, 4 years of that show and they never had any more names than that.
