My Little Stallion: Friendship is Magic

After a thousand years of being imprisoned in the moon, Nightterror Nebula has returned to Equestria, to finish what he started thousands of years ago. Upon hearing this Lord Solaris sends his personal student Dusk Shine to a little town called Ponyville to supervise preparations for the Mid-Summer Solstice Festival, and make friends with 5 other stallions named Applejack (or Jack), Rainbow Blitz, Elusive, Butterscotch, and Berry Bubble who end up sharing the magic of friendship with him, and purging Prince Artimis of the entity Nightterror Nebula once and for all completely .
