So one of the many new features in X and Y is the ability to make PR Videos. In Lumiose City there is a Studio that allows you to film these short videos, which star your character and Pokemon if you choose. You can add premade captions and special effects. Before you make them you can change your appearance slightly, like adding fake facial hair, or freckles. The videos are fun little clips that you can share with a passerby over the PSS.
Here is one of mine, with a bit of bad editing to spice it up.
