"Hmh, judging from the way this place looks, I would guess the gym leader uses bug-type pokemon." Kjolmar said to himself out loud. 

A female voice replied to him out of nowhere: "Your guess is correct. Let me introduce myself. My name is Viola and I am the gym leader around here. I must warn you however, if you've come here to battle my bug pokémon, there are two other trainers who walked in about a minute ago." 

While the other trainers came forward, Viola grinned. 

"I am feeling confident today so here's what we'll do. I will fight two of you at the same time. I'll use two pokemon at once and you'll each send out one pokemon. But once your choice has been defeated, you can not use another pokemon. Do we have a deal? Oh, and you might wanna decide among yourself on which two of you will battle me. I'd take on all three of you, but I only have two pokemon on me right now."
