One day, no matter your life before this moment, you went to bed and you wake up. There's a standard pokeball somewhere in your room/vicinity and it's glaringly obvious. Inside, is a random pokemon that has been entrusted to you by some force.

Generate a pokemon. The lowest evolution of that line is yours.

Pokemon has become real! Standard animals still exist, but they're no match for the new pokemon roaming around in environments appropriate to their species. These beings, not as cute and cuddly as the anime depicts, are nearly all powerful creatures with the ability to severely maim or even kill. With this, the government has demanded anyone who has either befriended a pokemon since they appeared or was entrusted with one forfeit them immediately. Black markets form for new trainers and pokeballs, if you can get in with the right people, are free and plentiful should you show you have what it takes to raise or train pokemon. What will you do?

Me personally, Pineco is a rather cool pokemon and I'd take him out into the forest and train him and use him to study other pokemon and try to train him into a forretress. Since I live in a somewhat isolated area, I don't think the police would be too focused on my area and especially not my Pineco.

My only real struggle would be preventing him from self-destructing as any Pokemon center, if there is one, would be secretive and it would likely take a little while to find one.
