Pokémon GS Vitro Pokédex: 350+ and How It Works

The GS Vitro Pokédex

More than 350 Pokémon are obtainable, across an expanded Johto and Kanto regional dex plus a few species from later generations. A full numbered list has not been published.

What is actually described

The download page says the Johto and Kanto regional dex was expanded and that more than 350 Pokémon can be obtained in the normal course of play, with a few species from other generations. The developer’s FAQ post adds mass outbreaks and a radio feature called “Sounds of…” as ways to meet Pokémon beyond the ordinary tables, including, in that post’s wording, any Pokémon over time.

I can repeat those mechanisms. I cannot turn them into a species checklist. No Vitro dex dump, number range, or encounter table was public on 2 November 2026.

The other Pokédex on the same site

Perseida’s own site navigation includes a Pokédex. That page is titled for Pokémon Perseida and lists Constela’s original species. Opening it will not tell you which of the 350 Vitro Pokémon you are missing. The comparison is on the Perseida page of this guide.

Questions

Can I see all 350 names here?

No. Printing a guessed national-dex slice would pretend the developer published one.

What is “Sounds of…”?

A radio segment the developer says can lead you to any Pokémon over time, alongside mass outbreaks. The post does not list the schedule.
