In Pokémon X & Y, like the past games, the trainer card changes colour based upon the various achievements you have accomplished within the game. There are several different colours for the Trainer Card, each dependant on whether or not you have passed certain milestones. The colours are as follows

These changes are done by following these instructions in any order.

• Defeat the Elite Four
• Complete Kalos Pokédex Dex
• Battle through one of the Battle Maison facilities and defeat the leader at the 50th streak

In addition to the trainer card, you have the option to open and view your badge case. Like the badges in previous games, you have the ability to tap these badges to bring up various information.

When you select the badge, you get a view of the Gym Leader as well as a 3D view of the badge.
