A few new details about the expansion have also been announced, including the first information on Galarian Slowbro.
As well as the new story content, new wild area and new and returning Pokémon already confirmed for the first DLC, several new moves and features will also be introduced and exclusively available within this area.
The Cram-O-Matic is a device available within the Dojo on the Isle of Armor. If you feed it four items, a new item, such as PokéBalls, PP Ups and even rarer items will be coughed up in return. If you've wound up with a huge collection of unused items thanks to Max Raids, this could be a great opportunity to convert them into something more useful instead.
A new, awkwardly named, item 'Armorite Ore' can be acquired through Max Raid Battles in the new Isle of Armor 'wild area'. This can then be exchanged for new tutor moves, including Burning Jealousy - a Fire type attack that deals damage to all opposing Pokémon, while burning any that had their stats boosted in the previous turn - and Grassy Glide - a new Grass type attack that has a boosted priority when Grassy Terrain is active.
A 'Max Soup', made of rare ingredients you must gather around the island, will also be available to treat your Pokémon to. This will allow you to, at the very least, give your starter Pokémon the ability to Gigantimax. We'll have to wait a couple of weeks to find out whether this is only available once for this purpose, or if it will allow you to make any Pokémon with a Gigantimax form capable of using it.
Finally, a new 'Restricted Sparring' battle style will also launch with the DLC. This limits the Pokémon types you'll be able to use in that battle, requiring some strategic choices in your teams and attacks.
Galarian Slowbro
Type: Poison / Psychic
Ability: Quick Draw
After Galarian Slowpoke was introduced alongside the announcement of the DLC itself, its evolutions, Slowbro and Slowking, have both remained a mystery. While Galarian Slowking won't be available until the Crown Tundra pack releases later in the year, the Isle of Armor will finally allow Galarian Slowpokes to evolve into Slowbro.
Moving on from Galarian Slowpoke's pure Psychic type, Galarian Slowbro is part Poison thanks to a Shellder bite setting off a "chemical reaction with the spices inside Galarian Slowpoke’s body" (the same spices that turned Slowpoke yellow).
Galarian Slowbro has a signature attack, Shell Side Arm, a Poison move in which it fires poisonous liquid from the tip of the Shellder attached to its arm. As well as potentially poisoning its opponent, it also inflicts either physical or special type damage depending on which would harm its target more.
Gigantimax Venusaur
Gigantimax Venusaur's G-Max move is Vine Leash. As well as dealing damage when used, this move also continues to deal damage for four turns afterwards to any Pokémon that isn't a grass type.
Gigantimax Blastoise
Gigantimax Blastoise's G-Max move, G-Max Cannonade, has the same effect as Venusaur's attack, except for any Pokémon that isn't a water type.
Both Gigantimax Venusaur and Blastoise will be available with the Isle of Armor DLC.
Any new and returning Pokémon, or new Max Raids, will be available to anyone that doesn't buy the DLC by trading with anyone that does, or joining their Raids.
We also got some of the first concrete details about the second, Crown Tundra pack, due out this Autumn.
Once you complete the adventure in the Crown Tundra, you'll be able to participate in the Galarian Star Tournament in Wyndon City. Much like the Pokémon League battles you can continuously retry after beating the main game, this will see you fighting rematches with the cast of Gym Leaders and more from the rest of the game. In this mode, however, you'll be able to choose one of them to team up with in a series of 2 vs 2 matches.
Finally, we got some firm details on the new Legendary Pokémon being introduced in this second expansion:
Regieleki
Type: Electric
Ability: Transistor (NEW - Effect currently unknown)
One of two new 'Regi' Legendaries introduced in this expansion, Regieleki brings with it a new Electric attack, Thunder Cage.
As well as causing immediate damage to its opponents, they will then find themselves trapped within this electrified cage for four-to-five turns, causing damage and trapping them in play.
We don't yet know exactly what Transistor does, but Regieleki is described as both "absorbing" electrical energy and its Electric attacks "pack the greatest power of any used by Electric-type Pokémon" - suggesting that it at least directly boosts Electric type attacks, as well as perhaps providing Regieleki with immunity to them itself.
Regidrago
Type: Dragon
Ability: Dragon's Maw (NEW - Effect currently unknown)
Supposedly created by Regigigas itself, Regidrago was sealed away unfinished by people fearing its destructive power should it ever have been completed. Regidrago is said to be able to use Dragon type attacks with greater power than other Pokémon, suggesting that its new ability - Dragon's Maw - also boosts its Dragon type attacks.
One of those attacks is its new signature move, Dragon Energy.
The more health Regidrago has remaining, the more powerful this destructive beam will be.
Galarian Articuno
Type: Psychic/Flying
Ability: Competitive
As well as a new type-pairing, Galarian Articuno has a new signature attack: Freezing Glare. This Psychic type special attack can also potentially freeze opponents.
Galarian Zapdos
Type: Fighting/Flying
Ability: Defiant
Galarian Zapdos's signature move, Thunderous Kick, is a fighting type physical move that can also lower the target's Defense stat.
Galarian Moltres
Type: Dark/Flying
Ability: Defiant
Fiery Wrath, Galarian Moltres' new signature attack, "transforms its wrath into a fire-like aura" to attack with. It can also make its opponent flinch.
