Just tossing some ideas around.

(Made with General Zoi's pony creator of course)

• Name: Lupus Lazuli
  
• Permanently broke his left wing in a flight school accident. This forced him to relocate to Ponyville. It doesn't bother him much anymore; he thinks living on the ground is pretty cool.
  
• Introverted. Generally a nice and friendly pony, but dislikes socializing in large groups of ponies.
  
• Enjoys studying the fierce and mythical creatures of Equestria. Claims to have seen various mythological beasts, but no one believes him.
  
• Competes with Fluttershy to see who can take down the most bears in an allotted amount of time. She usually wins.
  
• Suspected lycanthropic. Witnesses report seeing a wolfish animal with his fur colors roaming Ponyville at night. He has no recollection of such events, save for a few nightmares.
