Here's why:
* Pokemon Battle Revolution focuses on battling: The game revolves around online and offline battles, with the main goal being to compete and earn points.
* Outfit customization wasn't a feature: The game doesn't offer any customization options for your trainer's appearance or attire. You are limited to the default character designs.
You can, however, customize your trainer's appearance in other Pokemon games like:
* Pokemon Diamond, Pearl, and Platinum: You can customize your trainer's appearance in these games with a wide variety of options.
* Pokemon Black and White: These games also offer extensive customization options for your character.
If you're looking for shiny Pokemon, you can find them in the wild in various Pokemon games, including Battle Revolution, but you'll have to be lucky! The odds of finding a shiny Pokemon are typically 1 in 4096.
I hope this clears up any confusion!
