Crossover between Chōriki Sentai Ohranger and MLP.

One day Celestia asks Twilight about a certain legend that few ponies knew, much to her own amusement her faithful student dismissed it as something false.

Who knew that those silly tales were to, one day, reveal themselves to be true ?  

Will the mane 6 defeat the Machine Empire ? or are our equine friends doomed to a one-sided war ?
