Today’s Pokémon Presents video also revealed a whole bunch of information, details, and gameplay footage for early next year’s Pokémon Legends: Arceus, including two all-new evolutions of existing Pokémon and exclusive Hisuian Forms of a few other existing Pokémon.
While it was previously confirmed that the game took place far in the past in the Sinnoh region, it turns out that the region had a different name back then: the Hisui region (pronounced like “he-SU-ee”, according to the video), and there are certain regional forms of Pokémon in that region—forms that, from the seems of things, eventually died out entirely in the modern day world and Sinnoh region.
Players will not just have to battle against wild Pokémon in the region, but survive against them, as they can attack the player and if the player sustains too much damage they will be sent back to their most recent base camp—an interesting mechanic, as the player may be incentivized to sneak up on Pokémon.
Of course, the player can still battle these wild foes by using their own Pokémon, although the battle system is a bit different from the main series games, as there are two attack styles: the Strong Style and the Agile Style. Pokémon’s Speed determines not just who acts first, but also can give faster Pokémon multiple turns to attack with, especially if they go for an Agile Style move instead of a Strong Style one. It’s an interesting change to the tried-and-true formula.
New Pokémon
As mentioned earlier, at least two new Pokémon are in Pokémon Legends: Arceus, and the two shown below are both evolutions of existing Pokémon.
Wyrdeer (Stantler Evolution)
Wyrdeer is Stantler‘s evolution in the Hisui region. It is a Normal/Psychic-type Pokémon.
Basculegion (Basculin Evolution)
Basculegion is Basculin‘s evolution in the Hisui region. It is a Water/Ghost-type Pokémon. According to the lore, they evolve from Basculin that get possessed by the souls of other Basculin that can’t make the journey upstream. It’s a possessed ghost fish.
Hisuian Forms (Regional Forms)
There are also special regional forms for certain Pokémon in the Hisui region, referred to as Hisuian forms, similar to the regional forms from other regions.
Hisuian Growlithe
Hisuian Growlithe has a strong, rocky head with much more of a frontal mane than its usual form. It is a Fire/Rock-type Pokémon and they tend to watch over their territory in pairs.
Hisuian Braviary
Hisuian Braviary is the Hisuian-exclusive evolution of Rufflet. It is a Psychic/Flying-type Pokémon that has a powerful psychic ability it can invoke from its eerie screeches to create strong shock waves. Its description also mentions that this psychic power is used to boost its physical strength, suggesting it will remain more of a Physical-based attacker.
New Characters
Below are a few of the new characters revealed in today’s Pokémon Presents. Their full information will be added to the appropriate page in the Pokémon Legends: Arceus section of the website later in the day. These three form major characters in the Galaxy Team, who will help guide you, the player, as a member of the Survey Corps to complete the first-ever Pokédex for the Hisui region.
Captain Cyllene 
Commander Kamado
