Other-challenge: Only allowed to use moves(and/or their Pokemon) of one type from http://serebii.net/attackdex-dp/other.shtml <there.

No-save run: You literally can not save even once from start to finish, two black-outs and you RESET. Alternatively two or more faints in the same Gym Badge city/route and you RESET.

 

The first 6 pokemon you see, you must catch and only these 6. No starter allowed once you have acquired a full team.

 

Also known as the Pidgattata Gambit. 'Lucky' players will also enjoy the services of Metapod.

 

Hardest Pokemon challenge ever, Luvdisc only. To be nice, you can have 6 Luvdisc.

 

I once had a game where I'd traded my entire team and constantly levelled them so that they wouldn't obey me. I wouldn't recommend it if you're looking for a challenge, though: it was really easy. Amusing, though.

 

This seems like a challenge and a half. I shall save it for christmas, when I need an excuse to avoid my family.

Truly epic. The snorlax of challenges. Break out the poke flute!
