I'm really digging the OP's Abra idea. That sounds really nice. I could save so much money on gas and car insurance. I still enjoy a lot of things from my childhood, like the Pokemon games, but being grown-up just puts an interesting spin on them sometimes.
My favorite Pokemon is Dragonite but if I'm the only one in the world who is going to have a Pokemon and I'm not going to be a trainer or something, then I'd really like one who could serve a practical use. Machamp would make an awesome workout partner and bodyguard. Mewtwo would be a great friend to have just for the conversation and he's intelligent and self-sufficient enough that he doesn't need me to take care of him. Or what about a Ditto? Can't it just turn into the perfect Pokemon for most situations?
Ah who am I kidding? I want a monkey. I choose Chimchar!
