This is the battle of the brony-made and approved characters, Derpy Hooves vs Vinyl Scratch!
Derpy Hooves:
Achievements:
1) Ponyville’s Mail Mare
2) Appears in more episodes than any background pony
3) Fan-Made character
Weapons: Derpy has no weapons.
Advantages: Derpy has a very bubbly attitude. Possibly the reason for her cutie mark. Derpy can also fly.
Disadvantages: Derpy has wall-eyes. As far as the fans know, it could affect her vision. She is also an accident-prone klutz.
Vinyl Scratch
Achievements:
1) Professional DJ
2) Fan-given name- “DJ Pon-3”
Weaponry: According to fans, Vinyl has a “Bass-Cannon.” It is able to blast a huge beam of energy and obliterate whatever stands in front of it with hardcore music!
Advantages: Vinyl really has none as far as I looked into. Major fan-favorite in the brony community!
Disadvantages: Vinyl’s Bass Cannon will be rendered useless when Saxton Hale uses rage-mode. It will be out of commission.
