He wasn't the sweet boy in the green tights. Not even close. When we talk about who played Peter Pan in Once Upon a Time, we’re talking about a massive shift in how people view the boy who wouldn't grow up. Usually, Pan is the hero. He’s the whimsical kid taking you to a land of mermaids and fairy dust. But ABC’s Once Upon a Time (OUAT) flipped the script, and honestly, it was the best thing the show ever did.
They cast Robbie Kay.
At the time, he was this relatively unknown British actor with incredibly expressive eyebrows and a smirk that could make you feel safe or deeply unsettled. It depended on the scene. He took the role and turned it into a masterclass in televised villainy. Most people coming to the show expected a misunderstood teenager. Instead, they got a manipulative, ancient soul trapped in a child’s body. It was jarring. It was brilliant.
The Boy Who Became a Monster
It’s weird to think about now, but the buildup to Pan’s arrival was huge. Throughout the second half of Season 2, we kept hearing about "Him." The shadow. The leader of the Lost Boys. When we finally met the actor who played Peter Pan in Once Upon a Time in Season 3, the reveal was slow.
Robbie Kay didn't look like a threat. He was slight. He looked like a kid who should be in a classroom. But that was the point. The creators, Edward Kitsis and Adam Horowitz, wanted someone who could embody the "nasty" side of eternal youth. Youth isn't just about innocence; it’s about selfishness. It’s about wanting what you want right now without caring about the consequences. Kay played that selfishness with a cold, calculated edge that made him more terrifying than Regina or Rumplestiltskin ever were in those early seasons.
I remember watching the episode "The Heart of the Truest Believer." Pan is pretending to be a runaway Lost Boy. He’s "helping" Henry. You actually believe him for a second. Then the mask slips. That transition—from helpful friend to the architect of a nightmare—is why Kay’s performance stuck.
Why the Twist Worked So Well
The show’s big swing was making Peter Pan the father of Rumplestiltskin. Think about that for a second. The "Dark One," the most feared man in all the realms, was terrified of his own dad, who just happened to be a teenager in Neverland.

This backstory added layers to the performance. Kay had to act like he was older than Robert Carlyle. That’s no small feat. Carlyle is a powerhouse. Yet, in their scenes together, Kay held his own. He spoke with a cadence that suggested he had seen civilizations rise and fall. He wasn't just a kid; he was Malcolm, a man who traded his own son for a chance at immortality.
- He used his eyes to convey ancient malice.
- The way he tilted his head made him look predatory.
- His voice had this rasp that sounded weary but sharp.
People often ask if anyone else played the role. Technically, yes, because of the show's penchant for body-swapping. During a brief arc, Pan swaps bodies with Henry Mills. So, Jared S. Gilmore technically had to play Peter Pan for a bit. It was a fun diversion, but it only served to highlight how much Robbie Kay owned that specific brand of "Pan-demonium."
Shattering the Disney Image
We grew up with the 1953 Disney version. You know the one. He fights Hook, saves Wendy, and crows like a rooster. The version of who played Peter Pan in Once Upon a Time had to dismantle that image entirely.
In OUAT, Neverland wasn't a dream. It was a prison. The "Lost Boys" were kidnapped. The shadow wasn't a fun companion; it was a soul-ripping entity. Robbie Kay’s Pan used "belief" as a weapon. He didn't want Henry to be happy; he wanted Henry to die so Pan could live forever. It’s dark. It’s gritty. It’s exactly what the show needed to raise the stakes.
Honestly, the show kind of struggled after the Pan arc. It peaked there. The stakes never felt quite as personal or as dangerous as they did when the crew was stuck in the jungle trying to outsmart a teenager.
Casting the Perfect Antagonist
Casting is everything in a long-running series. If they had cast an older actor, the "Peter Pan" magic would have been lost. If they had cast someone too "pretty," he wouldn't have been scary. Robbie Kay had this specific look—angular features and those famous "villain" eyebrows—that made him look like he was constantly plotting.

He actually talked about this in several interviews during the show's run. He mentioned how he looked at the original J.M. Barrie text. If you go back and read the book, Pan is actually a bit of a sociopath. He forgets the children he "saves." He thins out the Lost Boys when they get too old. Kay leaned into that. He took the literary roots of the character and brought them to the screen in a way no one else had.
The Impact on the OUAT Legacy
Even years after the show ended, when fans talk about their favorite villains, Pan is always in the top three. Usually number one. Why? Because he was the first villain the heroes couldn't just talk down. You couldn't redeem him with a "True Love's Kiss" or a heartfelt speech about family. He had already rejected family. He had already chosen himself.
There’s a specific scene where he’s talking to Emma Swan. He calls her an orphan. He gets under her skin because he knows exactly what it’s like to be unwanted. It’s psychological warfare.
- Manipulation: He didn't use magic first; he used words.
- Fear: He used the environment of Neverland to isolate his victims.
- Ruthlessness: He was willing to kill his own grandson to stay young.
It’s interesting to see where the cast went after this. Robbie Kay went on to do Heroes Reborn and some indie films, but to the "Oncers" (the fanbase), he will always be the boy who never grew up—and the man who never should have been a father.
What You Should Know About the Actor Now
Robbie Kay is much older now, obviously. He’s moved on from the pixie dust. But he still makes appearances at conventions. He’s incredibly nice in person, which is a hilarious contrast to the monster he played on TV.
If you’re revisiting the series on streaming, pay close attention to the mid-Season 3 finale, "Going Home." The way Kay plays Pan's final moments—the desperation, the realization that he’s finally lost—is haunting. He doesn't go out with a bang; he goes out as a man who realized he wasted centuries on a lie.

Other Iterations of Pan
While Robbie Kay is the definitive answer for who played Peter Pan in Once Upon a Time, the character has a long history. We’ve seen:
- Robin Williams in Hook: The grown-up version.
- Jeremy Sumpter in the 2003 film: The classic heartthrob version.
- Levi Miller in Pan: The origin story version.
None of them, however, captured the sheer "villainy" that Kay did. He didn't need a CGI budget or a giant pirate ship to be intimidating. He just needed a campfire and a flute.
Final Take on the Neverland Arc
The Neverland arc is often cited as the point where Once Upon a Time matured. It stopped being just about fairy tales in a small town and started being about the high cost of magic. Pan was the personification of that cost. He was the bill coming due.
If you're looking for a deep dive into the character's psychology, you won't find it in a Disney cartoon. You have to watch Kay's performance. He managed to make us hate a child, which is a weird thing to accomplish, yet he did it with such charisma that you couldn't look away.
Actionable Steps for Fans and Researchers
If you're looking to dive deeper into the performance or the lore of the show, here’s how to do it without getting lost in the weeds:
- Re-watch Season 3, Episodes 1 through 11: This is the "Pan Cycle." It’s the tightest storytelling in the entire series. Focus on the subtext of Pan's dialogue; he almost always tells the truth, but in a way that hurts.
- Check out Robbie Kay’s interviews: Specifically from 2013-2014. He discusses how he developed the "Pan Smirk" and how he worked with Robert Carlyle to create a believable father-son dynamic despite the age gap.
- Read the original J.M. Barrie novel: "Peter and Wendy." You’ll be shocked at how much of the "villainous" Pan in the show is actually present in the original 1911 text. The show didn't invent a dark Pan; they just finally showed him to us.
- Follow the actor's current work: Keeping up with Robbie Kay on social media gives you a glimpse into how he’s transitioned from a child star to a working adult actor. He often shares throwbacks to his time on the show.
The legacy of the person who played Peter Pan in Once Upon a Time is one of subversion. It taught a generation of viewers that your heroes might be monsters, and sometimes, the person you should fear most is the one who promises you'll never have to grow up. Stay curious, watch the performance closely, and remember that in Neverland, "Peter Pan never fails." Except, of course, when he does.
