I'm currently doing a Red Nuzlocke Challenge. ^^
So far I'm doing well. Here are my set of rules:
1) Pokemon fainting = Dead.
2) Catching only one Pok/Road (exception for shinies, but there is no shinies in this game)
3) Not allowed to use "Fly".
4) Not allowed to catch legendaries.
5) Not allowed to fish.
6) Not allowed to have twice the same pok'
7) Not allowed to use repels.
The badges must me obtained in order. (Can't get the volcano badge before Saffron City.)
9) In case of blackout, the last pokemon used "survive".
10) Must battle every trainers in gym before going to the leader.
11) Name the rival something else than "Assbutt". (named mine Daniel.)
12) Must nickname every pokemon caught.
13) Trades aren't allowed before Sabrina's badge is obtained. And may only be used for evolution purposes.
14) Not allowed to buy pokemons from the casino.
15) Pokemons that complete the league challenge may be granted an "extra life". If anybody died during the Elite 4 / Rival battle, they can be used again but without this advantage.
16) Once the challenge completed (Champion, Mewtwo and legendary birds beaten) the pokemons I caught can be used in my next Nuzlocke --> Silver.) But won't be able to learn any Johto-exclusive moves.
At this point of the game, I just beat Blaine.
My team so far (I somehow managed to get ALL the pokemons I always loved):
Draco / Charizard - My starter. Also my cut slave.
Mako / Machamp - So far the one I love wasting my rare candies on. I named him this way because of Machamp's french name (Mackogneur).
Spec / Gengar - My "weetle favourite" if I may say. I named him after Haunter's french name - Spectrum. But he evolved since.
David / Alakazam - Not sure why I named him this. I felt extremely lucky I caught him before he teleported away \o/
Théodore / Nidoking - Took the first name I though of. Strenght slave but also a heck of a convenient fighter, especially against Ice type (Watch out, Lorelei.)
Marty / Tentacruel - My surf slave :B Can the word "slave" really be used if I use them in battle, BTW?
I also have an awesome Vileplume and an Arcanine but my team doesn't have enought slots. OTL
I should try a one-type-only challenge some days...
