As a writer, there’s a secret, terrifying, and exhilarating thing that can happen while you’re drafting: a character you intended for a minor role walks into a scene and refuses to leave.
They show up with a fully-formed voice, a riveting backstory you never planned, and a perspective so compelling it threatens to derail your carefully crafted plot. They aren’t just supporting the protagonist anymore; they feel like the hero of a different, fascinating story that’s happening just off-page.
That’s what I call “Main Character Energy.” It’s more than just being a fan favorite. It’s the powerful sense that a character has their own complete, vibrant world spinning within the larger narrative. Here are three secondary characters who radiate that energy, making their books infinitely richer.
1. Inej Ghafa from Six of Crows by Leigh Bardugo
Kaz Brekker may be the mastermind, but Six of Crows is arguably Inej Ghafa’s story of reclamation. A girl of Suli heritage sold into indenture, her quest isn’t about money; it’s about buying back her own life and hunting the slavers who stole it. Her entire arc is a classic hero’s journey of confronting trauma and forging a new identity, happening in the shadow of a heist. You get the feeling that if the book followed only her, it would be just as compelling, if not more so. She is the moral center, and her quiet, deadly grace makes her the novel’s true gravitational pull.
2. Kenji Kishimoto from the Shatter Me series by Tahereh Mafi
Kenji isn’t just the comic relief; he’s the narrator of the story we wish we were reading sometimes. In a series defined by intense romance and angst, Kenji is the only one with enough perspective to see the utter absurdity of their situation, and he’s not afraid to say it. His Main Character Energy comes from the fact that he has a life, a history, and responsibilities—leading the soldiers of Sector 45—that exist completely outside of the main love triangle. He’s the protagonist of a gritty, found-family story about survival that just happens to intersect with Juliette’s epic romance.
3. Nico di Angelo from the Heroes of Olympus series by Rick Riordan
Nico’s power comes from the fact that his most important character development happens between books, in the shadows. We see the cheerful, myth-obsessed kid, and then we see the brooding, immensely powerful Son of Hades. His transformation is so profound that it forces us to imagine the harrowing solo journey he undertook. As a gay Italian demigod from the 1940s, he is a man out of time and out of place, everywhere he goes. He’s the protagonist of a dark, gothic tragedy who occasionally wanders into Percy Jackson’s sunnier adventure story, reminding us that the world is much bigger and scarier than we thought.
These are the characters who prove that a story’s magic doesn’t always come from the person on the cover. They remind us that every person on the street has a life as vivid and complex as our own.
