This was a challenge I posed to myself, the other day over lunch:
Can I build a team of 6 Pokemon, with 12 types represented, within a given generation?
Easier said than done! Originally, I had Gen I on my mind. It was one thing, to put three or four together. But then I'd add a fifth, and a sixth member became impossible! That said, I did come up with a squad that works:
For Gen I (RBY):
For Gen II (GSC):
For Gen III (RSE):
Gen IV (DPP):
I could go on, but I think this makes the point. I am wondering - what 12-type teams can you come up with, either in the games and generations mentioned, or in more recent titles? I would be curious, too, whether your squad comes out quite close to mine, or else something completely different. Good luck, and have fun!
