Darien Fawkes

Darien Fawkes is a fictional character that first appeared in the 2000 tv show The I-Man played by Vincent Ventresca.

Darien Fawkes is a former career criminal and catburglar, who received multiple misdemeanor convictions and two felony convictions before he was thirty. Darien is described as having an "*above-average intellect*", and capable of being very deceptive. He and his brother Kevin were raised on a farm by their aunt and uncle after their mother died and their father left them (it is later learned that their father was a sniper for the government and after his cover was blown, he left his family in order to protect them). While Kevin became a scientist, Darien began a career as a thief while still in his teens. After being caught because he stopped to give CPR to a heart-attack victim, he was sentenced to life in prison without possibility of parole under California's three strikes law. This was where his older brother, Kevin, stepped in.
Kevin was a research scientist who had been working on a top-secret project. He cut a deal with his bosses to get Darien out of prison in exchange for using him as a test subject. When Darien agreed, he was then implanted with the Quicksilver gland, but Kevin's rush to remove Darien from prison meant that he implanted the gland before devising a way to remove it without killing the recipient. One of the other scientists, Arnaud DeFehrn, was actually a terrorist that had infiltrated the project, and led an attack on the research facility that caused Kevin's death and the loss of most of the project research. Darien escaped but was unwillingly drafted into The Agency, who had funded the project.
In exchange for the counteragent he needed to stay sane, Darien agreed, albeit reluctantly, to be an agent under their employment. Upon working with The Agency, Darien develops an affinity for his co-workers and opts to continue working there even after his dependency on counteragent is cured by Claire.
He has high morals for a career criminal – he could have easily escaped after his final break-in except he surprised the elderly owner into a heart attack, and stayed behind to perform CPR (unfortunately, the officers who caught him and the elderly man himself thought he was molesting the latter). He is a highly talented thief with expert-level breaking and entering skills, learned from his many incarcerations, and finds these skills quite useful in his new career as an espionage agent. His trademark expression is "*Oh, crap.*", usually said when he realizes he just got himself in trouble, although he also has a habit of quoting various other sources at least once in each episode (albeit in the form of a voiceover).
On one occasion, Darien was briefly possessed by the personality of Simon Cole, the previous owner of the gland, after Cole's residual RNA took over his body thanks to the imprint of his personality left in the gland, causing Darien to see Cole when he turned his eyes invisible and briefly act as him. Darien later attempted to use this 'quirk' of the gland to transplant his brother's RNA into his mind so that Kevin could work out a way to remove the gland or fix the quicksilver deficiency, but Kevin was unable to cure the madness and chose not to arrange for the gland to be removed as he felt it made Darien a better person.
Due to the gland, Darien has various powers beyond being able to simply turn invisible; he can turn his eyes invisible and see in infrared, his body temperature lowers to a point where he can cool drinks while invisible and escape heat-seeking weapons, he can turn others invisible so long as he remains in contact with them, and he can even turn parts of his body invisible while leaving the rest of him fully visible (Allowing him to, for example, pretend to be a double-amputee to infiltrate a hospital, or turn his head invisible to give the impression that he has killed himself to catch enemies off-guard).
