I would be the 7th gym leader in the region that you're in and would have a gym layout where you would have to think about where to go and what to do. You'll start at the beginning with a foggy forest scenery that you'll have to traverse through. Then after fighting a few trainers you'd find the exit to the next area related maze. And also, I love to use Normal type Pokemon.

In the second area, there's a lake with multiple sets of rafts and islands with trainers standing on top of them. Expect multiple Pokemon that are Normal type to have water related moves.

Third up, you have a fiery, sandy and desert like area to navigate through. Expect a lot of Pokemon with Flamethrower lol.

And last up, you have the area where I'll reside until your arrival. In this area it boasts a space themed look and has crystal platforms to jump and slide across. Then you'll come to me.
