Mary Sue: when your fanfic comes to life and ruins your day

Published on May 13, 2026 | Translated from Spanish

BOOM! Studios launches the miniseries Mary Sue, five issues written by Meghan Fitzmartin and illustrated by Lisa Sterle. The plot follows Cassie, a vampire fanfic writer who sees her original character, Jessica, materialize in the real world. The comic explores the chaos of mixing fiction with reality, as Cassie faces the exposure of her secret identity at school and the consequences of her fictional creation walking by her side.

A fanfic writer watches in horror as her vampire character, Jessica, comes to life and follows her to school, with a chaotic aura blending fiction and reality.

The narrative engineering behind the reality-fiction clash 🧠

Fitzmartin builds a structure where fandom functions as the narrative engine. The series uses metafictional resources to question the boundaries between the author and their work. Sterle's design supports this contrast: panels from the real world have muted colors, while Jessica appears with saturated tones reminiscent of vampire comic palettes. This technical approach allows the narrative to advance without relying on forced twists, leaning on Cassie's evolution as a writer and as a person. SECOND TITLE: Ironies of fandom: when your OC surpasses you in charisma THIRD PARAGRAPH: The best part of Mary Sue is that Jessica, the vampire created by Cassie, turns out to be more popular than her own creator. While Cassie deals with high school dramas, Jessica seduces everyone with her teen series character attitude. It's like your favorite fanfic came to life, but instead of giving you powers, it leaves you embarrassed in front of your classmates. A reminder that, sometimes, fictional creatures have a better social life than we do.

In a humorous tone 😄
