The Invisible Man (also shortened to "The I-Man" in Season 2) is an American science fiction television series starring Vincent Ventresca, Paul Ben-Victor, Eddie Jones, Shannon Kenny and Michael McCafferty.

It was cancelled by USA Cable Entertainment, Sci Fi's parent company, primarily due to the high production costs of visual effects.

[2] The series uses elements of science fiction and action to explore themes such as freedom of choice, determinism, and state bureaucracy.

The plot revolves around Darien Fawkes (Ventresca), a thief facing life imprisonment who is recruited by a spy agency that is constantly short on funds, and is given the power of invisibility via implantation of a special "Quicksilver gland" in his head.

However, the Quicksilver gland was sabotaged at its creation by scientist Arnaud DeFehrn to release a neurotoxin that accumulates in the bloodstream and causes intense pain, followed by antisocial behavior and psychosis.

His unconventional means included using his deceased brother's intellect to revive him and occasionally speaking with Arnaud DeFehrn, one of the gland's inventors, albeit these interactions typically ended with one of them being in pain.

Since the agency believed that the gland was too valuable to be taken away, Fawkes' personal pursuit frequently put him at odds with those in positions of power.

David Burke (Kevin Fawkes) and Armin Shimerman (Thomas Walker) also starred together in the short-lived The Tick live action series.

In the pilot episode, it was explained this was due to the fact that at the time the Department of Defense was having budget cuts while the DFG had a surplus of money.

As Quicksilver does not reflect light, it does not absorb it either; this drops the covered surface's temperature "below freezing;" however, it serves to insulate Darien against the extreme cold or heat.

It is also stated that Darien can suffer from "premature visibility" if he gets distracted or loses focus on remaining invisible, and extreme adrenaline surges can affect his control over the gland (in one instance, for example, Darien had to abstain from engaging in sexual activity as his body would automatically secrete Quicksilver during the adrenaline surge).

When in control of the process, Darien has demonstrated the ability to turn only parts of his body invisible, such as quicksilvering his eyes so that he can see in the infrared spectrum, turning his head invisible to lure his enemies into close range by making it appear as though he has shot himself, or concealing his arms or legs so that he could pass as a handicapped person for investigative purposes.

In the two-part episode "Money for Nothing", Darien has his counteragent confiscated by The Official as a way to force him into handing over cash he stole from DeFöhn's casino.
