Jangmo-o evolves to Kaulamo-o at Level 28, and then to Ikaikamo-o at Level 48, both of which are Steel / Dragon. There is a knight motif to it.

Topu Kali is a Water/Fairy guardian and is a large turtle with markings on its back that look like Alola.

Topu Kiai is a Grass/Fairy guardian who looks like the strange souvenier but covered in moss.

Topu Kapu is a Fire/Fairy guardian who resides in the volcano and prevents anyone from coming in (you have to earn its trust to go in). It looks humanoid, with a body of fire, and a wood mask covering its face with typical hawaiian looking markings.

Lialala is a Dark/Flying crow with a white face/black beak and a unique ability that tricks the user into thinking its a different type until hit with a super effective move.

The new monkeys are single stage.

There are 12 UBs altogether, five of which have alternate Sun/Moon appearances (like UB-02). Aether created the rift in which the UBs come through, though they created the rift entirely on accident. They pretend to research them after this when in reality they are using them to rid the islands of the guardians to awaken Solgaleo / Lunala. Team Skull is aware of this, which is why their goal is to capture Solgaleo / Lunala to fight the UBs.

Lillie isn't an UB, but rather, carries one of the UBs around in her bag. Lusamine is Lillie's older sister, and ordered the UB to protect her. The scene in the Japanese trailer where that UB is coming through a rift in front of MC, Hau and Lusamine is because Lusamine said it had to come back to the lab.

There is DLC content, all of which is free. It requires completion of the game, and the events start in January. The DLC gives you a new smaller island which you have to pass a test to unlock a roaming legendary. There are 12 in total, one for each month and 1 for each zodiac.
