>>35744617There's no official translation of course, they were never released and therefore never localized.
The team documenting this data plans on translating it (they planned on getting that done before releasing it but someone else started leaking it) so they've included the Japanese name, the Romanji, and come up with a suitable English name based on the Romanji with the context provided by the Pokémon's design and Japanese name origin.
"Turban" was "ta-ban" in Japanese, so that seems the obviously intended name.
"Minicorn" was "puchi-kon" which again was more or less going for "Minicorn"
If Umbreon was a new Pokémon they'd probably stick with "Blacky" (burakki) as the localization, since it breaks the naming convention of the other Eeveelutions in Japanese text, and since it's not Dark type there's no reason to invent the "Umbra-" connection. An alternative would be something like "Poiseon" but that's inventing something more than translating and it's pretty awkward.
