It's been a hard fought journey, to get this deep into the gym.
Trainer after trainer standing in your path, puzzles involving diverting the flow of lava, and worst of all...it's SO hot dude why did this guy import a bunch of lavafalls you're cooking alive in here dude.
Regardless, all your work has led here, facing the gym leader himself. His back is turned, but you can see a black backpack, an orange blazer, ripped jeans, and bright orange hair, with goggles on top. He's...acting...really dramatic.
"Trainer. You have fought well. Persevered through my expertly crafted gym..." Bit of a stretch. "...and now, here you are. Face to face with the ONE...the ONLY..."
He turns around, revealing two orange eyes shining with determination despite the bags under them.
"IGNIT- yawwwn ah. Uh- sorry- IGNITO!" He grins, clearly pumped. "Sorry about that, was up late doing battle plans. Anyway- are you READY, trainer?! >:D"
...well? Are you?
