Florina is annoying, but I poison powdered her Cradily with my bell sprout, and used got my one time use out of Makuhita, who revenged her health down and then whirl-winded Cradily away when it started to use curse.
The hardest gym leader in my opinion is Julia. I understand she is the first gym leader, and she is funny and peppy. Also, her name is one letter away form mine. But she is the hardest for 3 reason:
1.Sonic Boom-at a point in the game where most of my pokemon hardly had over 40 HP, if that. Sonic Booms can kill, and they hit everything, with no ghosts available yet, so no switch in is safe.
2. Self-Destruct-I don't know if this happened to anyone else, but of the 3 times I battled Julia, her second voltorb self destructed first turn, all three times....Why?
3. THE UNDER LEVELED ELECTRODE! First gym leader gets a fully evolved pokemon, even more so, the fastest electric type in pokemon?
