Imagine if the most dangerous enemies of Equestria: Nightmare Moon, Discord, Major Ursa, Manticores, Diamond Dogs. All of them united to conquer Equestria.
If the six Elements of Harmony are planning to stop them once again, they will need help... That is why Rocket Silver will answer the call. He once fought many battles, he can do it again.
NOTE: I didn't draw a helmet on Applejack because I'm aware of her love for her cowboy hat.
Took me four days to do it, I'm so tired... I hope it was worth the time.
