When Pokémon Pokopia launched less than two weeks ago, Joe Merrick did what he has done for nearly 25 years: he sat down to catalogue the game's secrets. Merrick runs Serebii.net, which has been operating since 1999 as a hub for Pokémon news and information. This time, he committed over 200 hours to documenting every creature, habitat, recipe, and hidden detail in the cosy life sim. The reward? Watching someone else turn his work into revenue.
A mobile app called Pokopedia positioned itself as a companion app where Pokopia players could look up information about monster habitats and specialities. Merrick noticed something suspicious: the app seemed to carry over some of the same gaps in knowledge that existed in his own guides while he was still building them. When Merrick had initially forgotten to list Snivy and Larvesta as possessing the Litter speciality, that same omission appeared in Pokopedia.

The evidence pointed in one direction: Pokopedia had copied information directly from Serebii, complete with Merrick's mistakes. Beyond the common errors, images in the app appeared to come from Serebii or from the official Pokémon HOME database, which Merrick himself had used only temporarily. The app, priced at $8.99 to remove advertisements, was making money from documentation created at no cost to its developer.
Merrick vented his frustration online. "With 200 hours work behind me on it, seeing my work just lifted and, in the case of the app, being used to make money...it hurts," he wrote. He added that while plagiarism happens with each new Pokémon release, Pokopia's viral success had accelerated the problem to an unprecedented scale.
The app's developer, Hugo Duarte, had faced similar questions before; he had also created a companion app for Stardew Valley. When contacted for comment, Duarte initially stepped away from the situation, removing all mention of Pokopedia from his social media. Days later, however, he released a statement defending his approach.

Duarte acknowledged using Serebii as one of several "publicly available community sources" after he found himself overwhelmed by data collection alone. "When a trusted source contains an error, that error can naturally carry over," he said, explaining that when he discovered Merrick's initial mistake about Snivy and Larvesta, he had unknowingly replicated it. Serebii has built a reputation as one of the most reliable sources in the fan community for timely, accurate reporting and an encyclopedic database, making it an attractive resource for someone seeking to populate an app quickly.
Duarte also pushed back against what he saw as unfair treatment. He claimed the backlash had "escalated beyond fair criticism" into "coordinated harassment," which prompted him to withdraw from public discussion. Still, he signalled willingness to engage directly with Merrick and committed to adding proper source attribution within the app.

The dispute exposes a lasting tension in gaming culture. Fan communities have always provided the legwork that makes reference tools valuable; fansites like Serebii.net operate on passion and volunteerism. But once that data exists in structured, usable form, commercial actors can rapidly package it into monetised products. Duarte acknowledged the imbalance by confirming he plans to credit Serebii and other sources going forward.
For Merrick, the issue was never simply about attribution. It was about the asymmetry of effort. Two hundred hours of unpaid labour had been compressed into a commercial product designed to generate revenue with minimal investment. Attribution might acknowledge the debt, but it does not restore what was lost. As the Pokémon community continues to generate and share knowledge freely, questions about who benefits from that generosity will only grow louder.
