1. Yep. Think Leonardo da Vinci but less wood. I have a very crude flying machine style
if you click here but there's also the flying bicycles, airships. Ever seen Treasure Planet? I wouldn't mind a steampunk surfer as well. If your going to have a flying machine, make sure you have some kind of explanation why. Unless you have an amazing reason or you already designed it and it looks awesome, couriers are the only ones I am accepting to have flying machines. UNLESS YOU WANT TO BE A BREEDER which we seem to have a shortage of SUs.
2. Yes, you can. The only thing I'm not allowing to happen to the human body is genetic modification like giving powers or Pokémorphs. You could have an iron lung! Just remember that having a bionic arm would make your character heavier and if you wanted a flying machine, you'd have to take that into consideration.
3. Yeah, I don't want to limit people too much on this RP. Creativity is the key and I want to make sure people can design stuff and be as creative as possible. Since you can't actually keep Pokémon handy in a Pokéball, I'd recommend 2-4.
4. No! I would LOVE to see you draw something. Like I said, be as creative as possible! I hope MORE people draw characters, Pokémon and scenes, no matter how crap they think they are. :D
