Galarian Ponyta's unique appearance is said to come from being exposed to the "life energy" of forests like Glimwood Tangle, giving it this unique form - and its glowing mane - in the Galar region.
As well as the Run Away ability, Galarian Ponyta can also have the new Pastel Veil ability. When a Pokémon with this ability enters battle, it automatically heals all allies of poisoning, as well as giving itself and all its allies immunity from being poisoned while in battle.
Despite being the only other new Pokémon to appear in the 'livestream', Impidimp remains unannounced entirely. Although it did sneak one further appearance into the official website's summary of the weekend stream.
We'll let you know the instant The Pokemon Company stops its cruel campaign of utter disrespect to poor Impidimp. As well as any other information in the final month's run-up to the release of Sword and Shield, of course.
