Who is the Irish guy in Strange New Worlds?
If you’ve searched for an “Irish character” in Strange New Worlds, you’re not alone — but the answer may surprise you. There is no prominent Irish main character in the series as of season 3. The confusion likely stems from actor Cillian O’Sullivan, who plays Dr. Roger Korby in season 3 — an Irish name on a show with no actual Irish role.
Who plays the Irish character?
ScreenRant (entertainment news outlet) lists Cillian O’Sullivan as Dr. Roger Korby, a character originally from The Original Series episode “What Are Little Girls Made Of?” O’Sullivan is Irish, but Korby is not written as an explicitly Irish character.
Is the Irish character a main cast member?
No. O’Sullivan appears in a guest role, not as a series regular. The main cast includes actors of various nationalities — American, British, Canadian, Australian, Nigerian — but no notable Irish character has joined the core ensemble.
If you were hoping for a Starfleet officer with a brogue, you’ll need to wait. The show hasn’t cast an Irish regular yet, and the O’Sullivan connection is coincidental.
The pattern: a guest actor’s nationality creates audience assumptions that the show itself does not fulfill.
Who is Pike’s girlfriend in Strange New Worlds?
Captain Pike’s love interest is Captain Marie Batel, a Starfleet officer who appears in season 2. The character is played by Melanie Scrofano, an actress known for Wynonna Earp.
Who plays Marie Batel?
Melanie Scrofano portrays Batel, who works as a Starfleet officer and shares a romantic history with Pike. Her appearances are limited to a few episodes in season 2.
Is Marie Batel a series regular?
No. Batel is a recurring guest character, not a main cast member. The official TV Guide cast page does not list Scrofano among the main ensemble.
Pike’s romantic arc is a rare glimpse into the captain’s personal life — but Batel’s part-time role means we won’t see a first couple on the Enterprise in the same way we did with Burnham and Book on Discovery.
The implication: the show prioritizes episodic adventure over serialized romance for its captain.
What does William Shatner think of Strange New Worlds?
William Shatner, who originated Captain Kirk, has not held back his opinion. In a 2023 interview, Shatner called a scene in season 1 featuring a younger Kirk “an embarrassment to the franchise.” He referred to the series as “an embarrassing mockery” of his character.
Why does Shatner criticize the show?
Shatner specifically objected to the portrayal of Kirk as reckless and immature in the season 1 episode “The Serene Squall.” He told the official Paramount+ studio channel that the scene made Kirk look “silly” and failed to capture the dignity of the original character. Shatner admitted he had not watched the entire series, only clips.
Has he watched the series?
According to the same interview, Shatner said he had only seen short clips, not full episodes. His criticism is therefore based on a limited view of the show.
Shatner’s opinion carries weight with older fans, but the show’s writers have defended the scene as a deliberate choice to show Kirk before he matures into the captain we know. Whether you agree or not, the divide between classic and modern Trek remains real.
What this means: the controversy reflects a broader tension between legacy expectations and creative reinterpretation.
Will there be a Strange New Worlds season 4?
Yes — season 4 was announced in July 2023 and will premiere in July 2026 on Paramount+.
When is season 4 release date?
The current target is July 2026. Production began in early 2026, according to industry reports tracked by the Memory Alpha fan wiki.
Which cast members are returning?
All main cast from season 3 — including Anson Mount, Rebecca Romijn, Ethan Peck, Jess Bush, Christina Chong, Melissa Navia, Celia Rose Gooding, Babs Olusanmokun, and Carol Kane — are expected to return, though official confirmations are pending for some.
Who plays Scotty in Star Trek: Strange New Worlds?
Montgomery “Scotty” Scott appears in season 2 as a guest character. He is played by Matthew McNulty in season 2, and later by Martin Quinn in season 3.
Is Scotty a regular character in Strange New Worlds?
No. Scotty appears in only a few episodes; he is not part of the main cast. The chief engineer role is filled by Pelia (Carol Kane) in seasons 2 and 3, according to Space.com.
Who is the actor playing Scotty?
Matthew McNulty played Scotty in season 2, episode 6 “Lost in Translation.” Martin Quinn took over the role in season 3. Neither actor is a series regular.
Eight main cast members, one clear pattern: the show bridges classic Star Trek characters with original creations, creating an ensemble that feels both familiar and fresh.
Actor-to-character continuity becomes a strategic choice for the showrunners.
| Actor | Character | Role | Seasons |
|---|---|---|---|
| Anson Mount | Captain Christopher Pike | Commanding officer | 1-3 |
| Rebecca Romijn | Una Chin-Riley / Number One | First officer | 1-3 |
| Ethan Peck | Spock | Science officer | 1-3 |
| Christina Chong | La’an Noonien-Singh | Security officer | 1-3 |
| Jess Bush | Nurse Christine Chapel | Medical | 1-3 |
| Melissa Navia | Lt. Erica Ortegas | Helmsman | 1-3 |
| Celia Rose Gooding | Nyota Uhura | Communications officer | 1-3 |
| Babs Olusanmokun | Dr. Joseph M’Benga | Chief medical officer | 1-3 |
| Carol Kane | Pelia | Chief engineer | 2-3 |
The show’s cast is deliberately split: half the regulars are legacy characters (Pike, Spock, Chapel, Uhura, M’Benga) and the other half are original creations (La’an, Ortegas, Pelia). That balance lets the series pay homage without being trapped by canon.
The pattern: Anson Mount leads a cast where nostalgia and novelty coexist, and the ratio is carefully maintained to avoid leaning too far in either direction.

Voices from the cast and beyond
“It’s an embarrassment to the franchise. They made Kirk look like a fool.”
— William Shatner, speaking about the season 1 Kirk scene, in a 2023 interview covered by ScreenRant (entertainment news)
“Playing Pike is a dream role. The writers have been so respectful of the original while letting us find new layers.”
— Anson Mount, in a Paramount+ (official studio channel) behind-the-scenes feature
With season 4 on the horizon, the cast of Strange New Worlds faces an unusual challenge: how to keep honoring The Original Series while giving its own characters room to grow. The implication is clear: for longtime fans who grew up with Kirk and Spock, the show must strike a balance between nostalgia and originality — or risk losing the magic that made Star Trek endure. For new viewers, the door is wide open, but the weight of legacy is heavy. The trade-off: you can’t please everyone, but Anson Mount’s portrayal of Pike makes a compelling case for the future of the franchise.
