Nintendo should give like a signed 3DS to anyone who does it :)
This, but it better be made of freakin solid gold too! >_<
I've never done it, and in all my years of playing pokemon I've only gotten my Vaporeon in pokemon yellow to 100, but OMG imagine doing them all... srsly can you imagine leveling up a Dunsparce to 100?? I'd die
And Unown would be the worst of all! *shudders at the mere thought and recoils at Hidden Power monotony* My thoughts on it were that if I ever were to train one, I would just stick in the Daycare after "EV Training" (ROFL :cer_laugh:) and hope it reaches Level 100...eventually. And oddly enough, I intended (and still do) to catch all 28 Unown variants and get them each to Level 100...yeah. That's "hardcore" Pokemon for ya. ;)
Oh Yeah, I completely forgot about Unknowns!!! they'd definitely be the worst of the lot!
OMG I really wish you good luck for your goal hahah I hope you survive the sheer mind numbing boredom that it will put you through!
