In a world far away, where smashing is a way of life and both heroes and villains alike can come together for a friendly competition, danger is brewing. A powerful villain known as Overlord V seeks to conquer the world--nay, the universe! The heroes are powerless to stop him, so a different faction rises to the challenge. Their plan, however, is something even the wittiest of the heroes of this world would never have figured out.
Equestria, a world not so far away. There resides Princess Twilight Sparkle and her friends. It's a normal enough day there... too normal. Time for something to happen. And that something? A dark angel and a small spherical knight with bat wings suddenly appearing on the scene and kidnapping Twilight. Can Twilight escape her captors? If not, can Rainbow Dash save her friend? And if all else fails, can Pinkie Pie prove to be the salvation of all that exists?
(Crossover with Super Smash Bros. for WiiU/3DS. WARNING: I haven't played all of the games included, so if I write some characters incorrectly (i.e. Marth, Rosalina, Fox, Olimar, etc.) I apologize upfront. ANOTHER WARNING: Since this is fanfiction, there will be shipping. If you don't know what that is, Google it. ONE MORE WARNING: Don't Google shipping. Trust me on this one. Just ask someone from the comments section. They're more likely to give you a less graphic response.)
(This isn't a warning: If you noticed the OC tag on this story, that's because I'm going to put Mii Fighters based on some of my Miis in this story. Take that, trolls of the comments section. I'm one step ahead of you.)
