"Heh, that was pretty sick."
>Defeat Speech
"A lotta trainers come here looking for an easy win, but what they don't understand is that sometimes there's no easy fix if you've got a bad bug. Things will usually get worse before they get better, but if you can roll with the punches and still come out on top? Then that's the mark of a great trainer. Here, take this ill-Badge.
And take TM06: Toxic too. Remember, you don't have to be a poison type to pass along a virus. You'd be surprised at how easy it is, and just how many Pokemon can use it too."
>Gym
The gym itself would primarily function as a water-treatment plant. They're using poison types like Grimer and Tentacool to filter out the toxins in swamp water and turn it into drinkable water for the rest of the town. The gym trainers themselves mostly use those Pokemon along with a few of the 'cleaner' poison types like Quilfish and Ivysaur, but nothing filthy like Garbador or Wheezing that can do nothing but pollute the water further.
The Gym Leader himself uses bulky poison types to stall out the trainer's party and let the poisons do their work. He'll use two Muk's, a Tentacruel, and a Dragalge to round it out. All of them would know Toxic, and Dragalge would have Venoshock to really hammer in the damage at the end.
If you walk around the town, you'll find out among the community that the Gym Leader used to have a wife that passed away by some mysterious sickness years ago. No one really knows how she died, but the GL's dialogue will clue you in on the truth.
It was Poke-aids
