Hi, I don't know what you're using for O Cristal Encantado: A Era da Resistência but a lot of it doesn't match up with the actual episode by episode credits (each one only credits a handful of characters, usually Rian, with everyone else lumped under additional voices, but most of the Skeksis are identified in one credit block or another). Credits are always the best source, and if something else is used, it should be cited.
Nothing wrong with that (we try to avoid it for character images and such, but for credits or sourcing info that's fine). Or if you can't screenshot, then read the credits and write down the names (I did that in notebooks for years). Or else leave any names out you can't confirm with the source. Otherwise a lot of it seemed to be guesswork or names that aren't actually mentioned.
