No seriously, the worst part of competitive battling of Pokemon is the move Toxic. I have so much trouble with Toxic as it always kill my Wailord, and it's clearly not my fault of not bringing Steel- or Poison-types. I'm not going to bring them because someone will eventually use Salazzle and he will have Corrosion to use Toxic on them. I keep declaring a ban on this movie on Smogon Forum, but all the mods did was lock my threads and tell me to follow the rules! How dare they tell me that is Toxic isn't bad, the fandom is TOXIC as well!
I am officially quitting Pokemon competitive battling and move on to the clearly superior competitive battling game that is Neopets.
