Power Rangers: The Supersonic Showdown

Power Rangers: The Supersonic Operation is a 40 minute special taking place before Power Rangers Super Megaforce exploring the origins and backstory of one of the "New Powers" teams. Footage used is adapted from Chikyuu Sentai Fiveman.

Synopsis
Before Super Megaforce, other Rangers teams were scattered across the galaxy. Witness the exploits of the Supersonic Power Rangers as they use music-based weaponry to close the curtain on the villainous Chevalier and his fleet of drone ships!

Summary
The Supersonic Rangers live on an Earth-like planet known as Serene. On Serene, the Rangers act as emissaries of the deity Genre, overseer of Serene and player of the "Eternal Rhythm," a song that maintains and preserves the ecosystems of the planet. A greedy band of mercenaries led by the treacherous Chevalier invade the planet using soldiers and monsters to seize the powers of the Rhythm for himself. Using energies from the Eternal Rhythm, Genre bestows her emissaries with the Anthem Batons: constructs that allow them to transform into the Supersonic Rangers so they may keep Serene safe.

After defeating many monsters, the Rangers discover a shocking secret: Chevalier was merely a brainwashed puppet of the true villain Adante, whose lust for power saw him consorting with minor powers to form an army strong enough to invade. Alongside a now-reformed Chevalier, the Rangers use the Rhythm RoboZord to lay siege to Adante's battleship "The Delinquent." After a fierce battle and an attempt on Genre's life, the Rangers manage to vanquish Adante at last. As opposed to returning their powers to Genre, they were permitted to remain Serene's protecors for life.

The end. Or was it?

Alas, no. Five years after the destruction of Adante, the Armada laid siege to Planet Serene. Serene saw it's end when Technical Officer Levira used a sound-based invention to play sour notes at a negative frequency, de-harmonizing the Eternal Rhythm and rendering the Supersonic Rangers powerless. As a final act of defiance, Genre bestowed portions of her remaining Rhythm Energy to each of the Supersonics and whisked them off of Serene using escape pods.

The Pink Supersonic Ranger crash-landed on Earth weeks prior to the Legendary Battle. Seeking revenge on the Armada, she covertly joined this planet's Power Rangers in battle against a massive swarm of X-Borgs, establishing diplomatic ties with the Alien Rangers of Aquitar in the process. When the battle was won, she left for space alongside the Aquitians. As they travelled, a light from her Anthem Baton confirmed the revival of the Eternal Rhythm.

It was time to return home.....
