After healing your Pokemon up at the Pokemon Center, you make your way towards the Toxi Gym. You enter to find that the gym puzzle is a strange one. You're asked with a question, and the correct answer, to the Gym Trainers, is considered 'the right opinion'. Answer with 'the wrong opinion', and you have to face one of the Gym Trainers. You have to hope that your answer is considering among the Gym Trainers to be 'the right opinion'. You eventually make it to the Gym Leader, Karen. She then battles you out of rage for having a different opinion to hers, that being that she's not the nicest Gym Leader. She sends in her Skuntank, as you defeat it. She then sends in her Salazzle, and you defeat it too. She then sends in Poizalynx, a Poison/Dark type, and the evolved form of Toxikitten. You defeat it, as she sends in her ace, Twittegird, a Poison/Flying type, and the fully evolved form of the regional bird, Karird. You defeat Twittegird, and beat Karen. She's still upset at you, but gives you the Venom Badge anyways because 'Its her job'. Your Rotom Pokedex yet again notifies you, congratulating you on the victory, and telling you your next stop is in Digndeth City, home of the Ground-Type Gym. After preparing to leave Toxi City, a Staravia swoops down and gives you a Letter from Professor Dragon-Blood. The letter says "Hello, (insert player name). I hope you, Jackson, and Isabelle are doing well on your adventures. I think you're ready now, in fact. You must be on your way to Digndeth City, right? Well, stop by Intega Town, and meet me at the Intega Academy. I think its time for you, Isabelle, and Jackson to learn about Mega Evolution!"
