You can earn badges by accomplishing great feats, like defeating powerful bosses or discovering new skyways. You’ll know when you earn a badge because text will appear in the middle of the screen, and you’ll also receive a notification.
Every badge you earn grants you a title that appears under your name, like “Sky Traveler”, as seen below:
You can select which title you display by choosing the Badge in the My Badges screen.
