Animated series are voice acted, so there are no live-action actors.
To find out the voice actors involved in the 2013 season of the Gormiti series, you'll need to specify:
* Which specific Gormiti series you're talking about: There have been multiple Gormiti series with different names, like "Gormiti: The Lords of Nature" or "Gormiti: Nature Unleashed".
* Which language version you're interested in: The voice cast will differ depending on the language of the series you're watching (e.g., English, Italian, Spanish, etc.).
Once you provide this information, I can help you find the voice cast for the specific series you're looking for.
