Patrick Gibson, who plays a younger version of Dexter Morgan in Dexter: Original Sin, has breathed new life into the iconic character. Set in Dexter’s 20s, Original Sin takes us back to a time when Dexter was grappling with both his dark urges and his social discomfort.

While fans may have been familiar with Michael C. Hall’s portrayal of Dexter, Gibson takes on the role of the serial killer’s life as a socially awkward forensic expert. The portrayal has sparked a fair amount of discussion, especially considering Dexter’s physique in the prequel. Yet, when you take a closer look at how Michael C. Hall, the original Dexter, carried himself, the evolution into a stronger, more muscular version of Dexter makes sense.
Patrick Gibson’s Dexter is too jacked in Dexter: Original Sin, but there is a solid reason that makes sense
In Dexter: Original Sin, Patrick Gibson’s portrayal of a younger Dexter Morgan has raised eyebrows for one major reason—he’s jacked. This version of Dexter, in his 20s, is visibly more muscular than fans may expect, especially when comparing him to the original Dexter series, played by Michael C. Hall.
But while the physical transformation might seem surprising, it makes complete sense when you consider Dexter’s role as a serial killer who needs to be at his peak physique to carry out his deadly work.

Dexter Morgan is no average forensic expert, he’s a methodical and ruthless killer. To succeed in this dangerous line of work, he requires not just intelligence but also physical strength. As a young man in his 20s, this is the time when Dexter would have been at his physical prime, before his focus shifted almost entirely to his work as a killer and investigator.
Dexter dresses in loose-fitting clothes to downplay his physique, intentionally keeping a low profile. The muscle mass Gibson’s Dexter shows is a logical representation of a character who would still be taking care of his body while balancing his emerging dark side.
It’s also important to remember that while Hall’s portrayal of Dexter was never about being overly muscular, he too had a solid and well-maintained physique. Hall’s version of Dexter was still in shape, and his physicality played a key role in making the character believable in physical confrontations.
Dexter in Original Sin is a callback to his younger years when he had more time to train and develop his physical strength—something that would be essential for a serial killer.

The reactions to Patrick Gibson’s portrayal of Dexter in Dexter: Original Sin continue to pour in on Reddit. Fans’ reactions to Gibson’s jacked portrayal have been mixed.

Some fans argue that it makes sense for a younger Dexter, who wasn’t killing as much, to have more time for physical training, resulting in a more muscular build. One user pointed out that as Dexter grew older, his focus shifted away from the gym, which explains his leaner appearance in the original series.

Ultimately, Dexter’s strength is an essential part of his character—whether it’s in Gibson’s version or Hall’s version in the original series. Dexter as jacked in his 20s serves as a perfect reflection of a character in his prime, ready to take on the world, both physically and mentally.
