Best Friend: Female

Okay! So, his best female friend is the instigator.

Now, I know very little about Pokemon so, it’s a challenge to think of a trigger.  Let’s see how this will play out. 

1) Best friend finds an oddly-colored pokeball and throws it playfully at him. He’s pulled inside, transformed and set free.

2) Playing Pokemon Go, best friends downloads what appears to be a new patch the PG3463. It appears that it will be a camera filter to turn someone into a Pokemon but, it actually transforms her friend.

3) Best friend finds a strange, high-tech remote control-looking device. She points it at her friend and he is transformed.

4) Best friend steals a cool-looking gun thing from her scientist brother. Points it at her friend and is transformed. 

Or, any other idea, you might have?
