The ruthless patriarch of The Argent Family, Gerard instilled hunting in his children and prepared them to face the supernatural. According to Chris, he manipulated Kate into being homicidal which eventually led her to decimate most of The Hale Family. He sent the young Chris on a gun trade with Yakuza members to see if he could adapt to the tense situation.
When Derek Hale was a teenager, Gerard and Chris lead a hunting party to avenge two of their own. When the Alpha Deucalion arranged a meeting of the two groups to talk about peace, Gerard turned the tables on everyone and killed Deucalion's Betas and his team of hunters to make it look like Deucalion ambushed them. He blinded the Alpha before leaving the scene.
He would return to Beacon Hills, later after his daughter's death to avenge her. Revenge was a cover. His real agenda was to receive the bite of an Alpha to cure his cancer. During this time, he attempted to manipulate Allison the way he did Kate, take control of a Kanima and have Hunters forsake the code to achieve his goal.
His plan failed after Scott McCall, and Dr. Deaton switched his cancer pills with Mountain Ash which caused his body to reject the bite. It cured Gerard's cancer, but he suffered what appeared to be prolonged rejection marked by a constant flow of black goo from his nose and mouth.
Gerard was healed from his prolonged illness by Chris by ingesting Yellow Wolfsbane flowers to stop the flow and return to normal. Chris and Scott needed his help to stop the Dread Doctors from reviving The Beast of Gevaudan. Gerard planned to double-cross them, but the duo knew it would happen, and they turned on him first. Chris shot him in the arm, preventing him from doing any real harm.
