My top five hardest Pokémon to train? Ok. In a FireRed nuzlocke I did once, I fished a Magikarp up in Vermillion. I then decided to train it up, since most of my team were useless against Rock Pokémon. Boy, was it a waste. When it evolved in Rock Tunnel, I found out it learned no water moves! I ended up wasting Water Pulse on it, and it was rubbish. I ditched it in Celadon for Vaporeon. Much more useful. (thinks I should finish it) Another was my little Oshawott in my Black. Since it was my first Pokémon game, I was silly. I mainly focused on the guy, with one big problem. I didn't let it evolve. As a result, he got killed all the time in end-game. Mind you, his Hydro Pump OHKOd Tornadus since he was so overleveled. Otherwise, I had no real problems, other than me being silly. *thinks back to running Emerald with three Pokémon" I remember giving up on a Lillipup one level before it evolved, since I was getting sick of waiting. I evolved it when I started to empty my Black cart into Bank. I can't think of two others, I'm afraid.
