ShadeStrider@ those are some great ideas. Like you I'm not a really fan of the silent MC route either. I have their own personalities and motivations for battling team meteor. Like for Example;
After the events of Black 2 and White 2, Losing his parents from the destruction left by Kyruem and team Plasma, Vero was sent to an orphanage to try a new start for the lonely child. Sadly, Vero wasn't normal child, never gotten over the death of his family, Vero became a loner never trying to make friends, never relying on others for help, people thought he was a cold person who has a disdain for people but, in reality he has fear of getting attached to others and losing them as he lost his parents. 10 years later, getting tired of living in the region of his family's death Vero earned a train ticket to far away region know as the Reborn Region.
