Governor Conrad Grayson is one of the main antagonists in the ABC Family series Revenge. He is the former CEO of Grayson Global, an investment trust with assets of four billion dollars. He is also Victoria Grayson's former husband and the head of Grayson family.
He was portrayed by Henry Czerny
He has laundered money for the terrorists who crashed Flight 197 and killed 246 people. He has framed David Clarke, one of his subordinates, by committing perjury and corrupting numerous witnesses (Lydia Davis, William Harmon, and many others) and the vice-attorney Tomas Kingsley. He and Victoria have paid Leo "Mason" Treadwell to tell lies in his book about Clarke's figure. He ordered "the white-haired man" to murder Clarke and Lee Moran.
Conrad took over the company when his father, its founder, semi-retired and became Chairman of the Board of Directors. When his first marriage turned into a disaster he married his second wife, Victoria, in 1986 and their first child, a son and heir, Daniel, was born not long after.
In 1993, Conrad was laundering money for a terrorist group who in the same year blew up Flight 197, killing 247 people (it was later revealed that he was unaware of what they were planning). When thecame close to being exposed, Conrad needed a fall guy and had the terrorists frame David Clarke, a Grayson Global executive who was then having an affair with Victoria. Eventually, Conrad pulled Victoria and many of their friends into the conspiracy to frame David and got him convicted.
Conrad is ruthless and willing to do whatever it takes to ensure he slithers out of potentially scandalous situations unscathed—and he’s got the skeletons of previous scandals to prove it. They are unaware that's daughter Amanda Clarke, under the alias Emily Thorne, has returned to the Hamptons to seek justice.
In "Pilot" Conrad met with Lydia, his lover. But when he was in the South Fork Inn he had an attack. Then at thediscovered that he was having an affair and told him not to do it again. Then at the Memorial Day Party he saw how Victoria kicked Lydia out of the party.
 Conrad discovers that Lydia has lost everything. In "Trust" Conrad attended Daniel's polo match where Lydia constantly called him. She picked her up in a corner and she told him that she had lost everything because somebody (Emily) sent photos of her and Conrad to her husband Michael.

She then plants the gun Aiden used to kill him in the trunk of Conrad's car. In jail, Conrad is visited by Helen, a member of Americon Initiative, who offers to get him out of custody in exchange for some future service. He accepts, and is thus on the Initiative's hook again.
In "Power", Conrad has a talk with Judge Robert Banners about his life after Grayson Global and is inspired to run for public office. Over the following few episodes, Conrad prepares for his campaign by making positive media appearances. In Sacrifice, he makes a public announcement that he will be running for governor.

In "Engagement", just a few days before the gubernatorial election, Conrad gets the lead in the polls when his opponent, Mark Stoddard, is revealed to the public to have a heart condition, leading many to believe that he is physically unfit for office and apparently securing the election in Conrad's favor.
At the end of "Truth, Part2", Conrad is the projected next governor of New York. Though the season ends before the official election can take place, with Stoddard's condition out in the open, he has the win more or less in the bag. Near the end of the episode, Conrad is revealed to have become a member of the Initiative after being arrested in "illusion" when Helen approached him. During the first part, he took precautions to clear the Grayson Global building and get Daniel to his campaign headquarters to keep him away from the bombing. He also used Ashley's phone to lure Jack to the building. As everyone attending a speech gets text messages reading "Long Live David Clarke", Daniel sees Conrad turn to look at the Grayson Global building right before it explodes. He then uses the incident as an opportunity to show off in front of the news cameras. When they later meet at the damaged floor, Conrad slips and reveals himself to be a member of the Initiative. When Daniel tells Victoria about their conversation, she confronts him as well and he confirms it, explaining that he was let into the organization as a condition of his helping them in the future, giving him knowledge of their operations. The episode ends as Emily stops Jack from killing Conrad, who is holding a speech, his victory in the election practically inevitable. However, Ashley still has the recording of Conrad and Nate Ryan's conversation, which she is planning to play in front of everyone and which could become a fork in the road for Conrad.
In "Fear" Conrad is officially governor and is already considering a run for president but when he was making a speech at the unveiling of his governor's portrait, he collapses. At the hospital, he and the family learn that he has Huntington's disease, a degenerative and ultimately terminal neurological condition that affects the body's motor skills and mental acuity. The doctor suggests that he retires from office as stress accelerates the disease, but Conrad says no, saying his grandfather was able to work full-time until retirement with the disease. However, at the end of the episode, it's revealed to the viewers that Emily altered the doctor's report to show that Conrad had the condition and that his collapse had been caused by Emily drugging him.
 Conrad loses CharlotteIn, "Sin", Conrad is visited by Father Paul, who encourages him to confess his sins. Conrad initially rejects the offer, but changes his mind after Charlotte disowns him when she finds out from Jack that he knew about the bomb at Grayson Global that killed Declan.

 Conrad decides to confess In "Confession", Paul helps Conrad get to the place where he is ready to turn himself in and clear David Clarke's name.

Conrad Grayson is selfish, ruthless and disloyal. But something that comes up later in Season 3, is that he shows his more affectionate side. He doesn't want guilt hanging over him, he wants to let it out to the world (reasoning for writing his memoir). Conrad is loving towards Emily and has always helped her in anyway that he can, never once has he tried to ruin her, even though he has tried that with Daniel. He has a very sweet, sensitive side that he rarely shows and close attention needs to be paid to recognize this in him. One thing he shares in common with his ex-wife is that he had at least one affair while they were married. Although he claims to love Victoria, they often argued and had a very unhappy marriage which eventually ended in divorce. However, Conrad does genuinely love his children, comforting Charlotte after she left home and trying to get Daniel to join the family business, although he also considered having Tyler Barrol take the job.
Tyler claimed that Conrad was weak since Conrad only ever acted in his own interests, not caring about the welfare of others. He was willing to let Tyler shoot Emily Thorne because he refused to reveal that he had framed David Clarke. Ironically, he had told Tyler only moments earlier that he wouldn't be shooting anyone.
