An ill-advised experiment to draw upon a source of extra-dimensional energy causes the Earth to break the dimensional barriers to the Vyram home. In retaliation for the invasion and having recognised Earth as a viable location for their expanding empire, the Vyram chose to annexe Earth as the first part of their expansion into a new galaxy.
To protect the planet the Sky Watch organisation recruited five humans possessing high levels of Birdionic Radiation to become Sky Force Rangers.
