Summary: When Rainbow Dash performs her first Sonic Rainboom as a filly, she causes a young filly Twilight Sparkle to shoot several beams into the sky. Ten years later, those beams appear in various different worlds and teleport characters from Super Smash Bros., DC Comics, Marvel, Star Wars, Percy Jackson, and a regular human into Equestria. Not long afterwards, an old foe of Luke Skywalker’s terrorizes the land. And when a new foe, even deadlier than any enemy ever before seen, is born, he wishes to destroy the Elements of Harmony. If he succeeds, Equestria, followed by the universe, will crumble. Not only that, but the human has connections with him. Connections which make things worse. Together, the group must stop this foe. The stakes have never been higher, and if they fail, the universe will fall.
