Lauren Faust. Go Nagai. It is unknown which of these creators would win in a Reeses Peanut Butter Cup eating contest. It is my opinion, however, that their creations, namely the ponies of Equestria and giant super robots, go together like chocolate and peanut butter.
The terrible Doctor Tartarus wants to rule the world, and only Professor Celestia and the brave ponies of the Harmonic Research Institute stand in his way. Bent on the total annihilation of all who resist, the twisted draconequis sends forth his villainous lackey, the dreadful half unicorn/half pegasus Princess Trixie Dust, at the head of an army of giant robot monsters. It's up to the Institute's mighty robotic guardian, Marezinger Z, piloted by the brash pegasus Rainboji Dash, to save the day and defend Equestria and the world.
Please enjoy.
