Eminem surreptitiously invites rappers of all blackgrounds to participate in a 'rap battle' but is actually a kick into a portal to Equestria. Drake is the only one who can save them.
Warning: Sparity. Spike learns of a motto from his teenage drake kin which bears a great deal of magical power. So great that all of the ponies either bow down to him or think he's an absolute moron.
NONE of Twilight's study methods work, not even when Twilight tried to take advantage of Rainbow's coordination skills. So Pinkie comes to save the day, but not without a little assistance from Lil Wayne himself.
The Dazzlings put forth a challenge to everyone at Canterlot High, but really they have nothing in mind that would pique the interest of anybody. However, hope is around the corner since a certain artist is around to help.
Based off episode 12 of season 5, Twilight remembers her old friends, a bunch of world famous rappers from the ghetto. She makes amends with one of them. Not a serious fic.
