If you’ve been following the Kent family through the windswept fields of Smallville, you know the deal. For three seasons, Jonathan Kent was the "human" one. He was the kid who lost his status as a Metropolis QB, moved to a farm, and watched his brother Jordan get all the cool Kryptonian party tricks. It was frustrating. Honestly, it was sometimes a little heartbreaking to watch him stand on the sidelines while his twin flew through clouds.
But everything changed in Season 4.
The Jonathan Kent Power Up We All Waited For
Let’s be real: the "powerless Jon" arc was getting a bit stale. We saw him try the X-Kryptonite thing (big mistake), try being a firefighter, and try being the emotional anchor for a family that literally carries the weight of the world. Then came Season 4, Episode 3, titled "Always My Hero."
It wasn't a slow burn. It wasn't a "maybe I can hover an inch off the ground" moment like Jordan had in the early days. Jonathan Kent basically hit the jackpot all at once. An emotional explosion triggered his dormant Kryptonian DNA, and suddenly, he had the full suite. Strength, speed, heat vision, the works.
What’s wild is how much better he seemed to handle it than Jordan. While Jordan struggled for years to stabilize his abilities, Jon stepped into the role with a natural grace that almost felt like a slap in the face to his brother. It created this messy, beautiful, and incredibly tense sibling rivalry that actually made the final season worth watching. General Sam Lane was ready to suit him up as the next Superman almost immediately.
That Time the Actor Literally Changed Overnight
You can't talk about Jonathan Kent without addressing the elephant in the room. Or rather, the different face in the room.
Between Season 2 and Season 3, Jordan Elsass—who originally played Jon—decided to step away from the show. It was a massive shock at the time. Elsass cited mental health as a primary reason, needing time to focus on himself away from the grueling production schedule in Vancouver.
Enter Michael Bishop.
Replacing a lead character in a tight-knit TV family is usually a recipe for disaster. Fans are protective. We notice when a kid suddenly grows three inches or speaks in a different register. But Bishop pulled off a minor miracle. He didn't try to mimic Elsass’s "cocky athlete" vibe. Instead, he brought a softer, more grounded energy to Jonathan.
By the time Season 4 rolled around, most of us had stopped thinking about the recast. Bishop’s Jon felt like the version of the character that was ready to inherit the cape. He looked more like he could actually be related to Alex Garfin (Jordan), and his chemistry with Tyler Hoechlin’s Clark felt lived-in and authentic.
How the TV Version Divides Comic Fans
If you pick up a DC comic right now, the Jonathan Kent you see there is... well, he’s different.
In the books, Jon is often an only child. He’s the one who became Superman while his dad was off-world. He’s also famously bisexual, a storyline that Superman & Lois showrunner Todd Helbing decided not to adapt for the TV version.
- Comic Jon: Has a cape from age ten, travels through space, and eventually gets aged up by a villain.
- TV Jon: Starts as a "normal" jock, has a twin brother, and spends years just trying to find a purpose without powers.
Some fans hate that the show diverged so far from the source material. They wanted the "Super Sons" dynamic from the comics where Jon and Damian Wayne (Robin) go on adventures. Instead, the show gave us a domestic drama about identity. But honestly? The show’s version feels more human. Watching a kid deal with the fact that he isn't special is a much more compelling story than just giving him a "S" on day one.
The Firefighter Arc: A Stroke of Genius or a Filler?
Before the powers kicked in, the writers put Jonathan through the ringer. The firefighter storyline in Season 3 was divisive. Some people thought it was boring—just a way to keep the actor busy while the "real" plot happened elsewhere.
I’d argue it was the most important thing to happen to his character.
Working under Kyle Cushing at the Smallville Fire Department gave Jon a sense of heroism that didn't depend on yellow sunlight. It proved he had the "Superman heart" before he had the Superman muscles. When he finally did get his powers, that foundation of service meant he wasn't just a kid with a weapon; he was a first responder with an upgrade.
What Most People Get Wrong About His "End"
As the series wrapped up in 2024, there was a lot of debate about who "won." Did Jordan become the hero? Did Jonathan?
The truth is more nuanced. The show wasn't ever about who was the strongest. It was about the legacy of the Kent name. Jonathan’s journey from the popular kid in Metropolis to the forgotten son in Smallville, and finally to a hero in his own right, is the emotional spine of the series.
He didn't replace his father. He became the bridge between the human world Lois inhabits and the god-like world of Clark.
If you're looking to revisit the best of Jonathan Kent, go back and watch the transition in Season 3. Pay attention to how Michael Bishop handles the quiet moments of frustration. It makes the payoff in Season 4 feel earned rather than just a plot device to wrap up the show.
Next Steps for Fans:
- Watch Season 4, Episode 3 again to see the exact moment the powers manifest; the VFX in that scene are some of the best in the series.
- Compare the "Bizarro-Jon" from Season 2 with the Season 4 version to see how the show foreshadowed his potential for power (and the danger that comes with it).
- Check out the "Super Sons" comic run by Peter J. Tomasi if you want to see the version of Jon that inspired the character, even if the show went in a totally different direction.
