maintained a constant presence in the action genre. He reunited with Miller in Legends of Tomorrow

The mastermind. The genius with the heart of gold. The Look: Low body fat, intense blue eyes, and that signature buzz cut. Why He Was Hot in Season 4: Michael Scofield was the ultimate thinking woman’s crush. In Season 4, his character took a darker, more desperate turn. The "hotness" factor here was his intelligence and unwavering loyalty. Plus, the physical transformation—showing off a lean, athletic physique during action sequences—didn't hurt.

Sarah Wayne Callies, who played Dr. Sara Tancredi, the prison's doctor and Michael's love interest, brought a touch of elegance and sophistication to the show. Her stunning looks, combined with her exceptional acting skills, made her a fan favorite. Callies' chemistry with Miller was palpable, and her character's complicated relationships with Scofield and Lincoln added depth to the show.

The comeback king of Season 4. In earlier seasons, Mahone was the terrifying Fed. In Season 4, he is an ally, a drug addict, and a grieving father—and somehow, that vulnerability makes William Fichtner scorching hot.
