Welcome to the club Blues! Hope you'll have fun :D
Any specific reason you chose Chili exactly? I personally like him the best out of the Striaton trio because he just appears to have such an interesting, fiery personality, however I don't know about you.
Seems there isn't much more to this topic, so we'll be moving on :D
Which of the gym leaders, excluding Brock, Misty and Cilan, do you like the most based on their anime appearance? If you haven't watched the anime, feel free to just tell which gym leader you like the most.
