Okay, folks, let's talk about Rick and Morty. It’s a show that throws a lot at you. Weird aliens. Crazy adventures. Existential dread disguised as jokes. It’s got a whole universe of characters. Some are regulars. Some pop in for an episode. And then there are the guest stars. The ones who really, truly, stick with you. And I’m here to make a bold claim. A possibly unpopular, but in my heart, totally true claim.
Nathan Fillion is still the undisputed king of Rick and Morty guest stars. Yes, I said it. Fight me. Or, you know, don't. Just hear me out.
Now, I know what you're thinking. “But what about so-and-so? They were hilarious!” Or, “Remember when that celebrity voiced that character? Iconic!” And I agree. Rick and Morty has a knack for bringing in some seriously talented people. People we know and love from other shows and movies. People who can deliver a perfectly timed groan or a maniacal cackle.
But Nathan Fillion. Oh, Nathan Fillion. He’s like that perfect topping on an already amazing pizza. He elevates it. He makes it even better. He strolled into the show as Gobo, a character that on paper sounds like… well, a bit of a gimmick. A galactic tourist. A guy who’s way too into something.
And he was all those things. But Nathan Fillion made him real. Or as real as a guy who gets his head stuck in a wormhole can be. He brought that signature Fillion charm. That effortless charisma that makes you instantly like him, even if he’s being a little bit of a buffoon.

Remember that episode? Season 4, episode 2, "The Old Man and the Seat." Rick is trying to find a toilet that’s solely his. A private place for his… business. And Gobo is there. He wants the toilet too. He’s determined. He’s got this whole thing about claiming seats, marking his territory. It’s ridiculous. It’s petty. And it’s hilarious.
But the magic is in the delivery. Nathan Fillion doesn't just say the lines. He inhabits Gobo. You can hear the earnestness in his voice. The slight desperation. The misguided sense of entitlement. He’s not just a voice actor; he’s a character actor. Even for one episode. He gives Gobo a soul. A silly, annoying, but ultimately understandable soul.

And let's not forget the sheer relatability. Who hasn't had a minor turf war over something utterly trivial? Who hasn't felt that tiny thrill of claiming something as "theirs"? Gobo tapping into that primal, idiotic part of all of us. And Nathan Fillion just gets it. He makes it funny without being mean. He makes it absurd without being unlikable.
He’s the guy who’s really into his niche hobby. The guy who’s fiercely protective of his favorite armchair. The guy who’ll argue about the best way to load a dishwasher. Gobo is that guy. And Nathan Fillion makes him a star, even if for a fleeting moment.

Compare that to some of the other big names who’ve lent their voices. They’re often brilliant. They’re often hilarious. But sometimes, they feel like the celebrity playing the character. Like they’re just doing a voice. Nathan Fillion, on the other hand, becomes Gobo. He’s not just visiting Rick and Morty; he’s adding to its tapestry.
He has this incredible ability to be both completely absurd and surprisingly grounded. He can deliver lines that are so over-the-top, you’d expect them to break the fourth wall. But he delivers them with such earnestness that you believe it. You understand it. You might even sympathize with it.

"He’s like that perfect topping on an already amazing pizza."
It’s that subtle nuance. That level of performance that elevates a character from a punchline to a memorable personality. Even a tiny, one-off personality. Gobo could have been forgettable. He could have been just another one of Rick’s annoyances. But Nathan Fillion made him shine. He gave him a moment in the sun. A moment of pure, unadulterated, toilet-claiming glory.
And that’s why, in my book, he’s still the best. The gold standard. The guest star that sets the bar so high, it’s practically in another dimension. He embodies the perfect blend of Rick and Morty's chaotic brilliance and the sheer joy of a perfectly executed performance. So next time you rewatch that episode, pay attention. Really listen. You’ll hear it. You’ll feel it. The undeniable, unassailable truth of Nathan Fillion’s Gobo.
He’s not just a guest star. He’s a legend. A Gobo-sized legend. And that, my friends, is something to smile about.
