It cannot be Coulson, May, Daisy, Mack, Fitz, Simmons, Bobbi, Hunter, Tripp, Yo-Yo, Lincoln, Joey, or Ward.
I’ll start, my favorite character is Calvin Johnson, aka Daisy’s father. He is the most compelling character, not becuase he is a villain, but becuase he “JUST WANTED RO PUT HIS FAMILY BACK TOGETHER!” He was broken volatile man whose daughter was taken from him, his wife was butchered by a monster and then became a monster herself and he had to keep his promise to her by killing her. He is anti-villain in my opinion. Not a villain. He is the reason why I think season 2 is the best season of the show. He just wanted his daughter back. Every time he was on screen I wanted to give this man a hug.
Kyle MacLachlan is truly amazing actor. If they will be making some kind of show about Johnson family, I wouldn’t want anyone other than him to play this role.
