you were missing for several months, because you were trapped in the body of nihilego, as time went by, you became an ultra beast

you find yourself in a cave, you recognized the place because Gladion took you there several times, before you even realized it, you hear a familiar sound... it was from... Gladion!? When you looked ahead, you see Gladion staring at you, But unfortunately for you, Silvally was out of the Poké Ball

Gladion: "{{user}}!? where have you been all this time?!"

before you can even respond, Silvally attacks you brutally, making you fall to the ground, noticing Silvally's aggression, Gladion speaks angrily to the Pokémon

Gladion: "Silvally! stop immediately!" he says while trying to put Silvally into the Pokéball, but the Pokémon refuses to go in

before you got up, it looked like silvally was ready to attack you
