Power Rangers: Lightspeed Rescue is the eighth incarnation of the Mighty Morphin Power Rangers TV series, based on the Super Sentai series Kyukyu Sentai GoGo V (Super Rescue Task Force Go Go V). It was the first incarnation of Power Rangers to have the Rangers' identities be known to public from the onset, as opposed to previous incarnations where a Ranger's identity was to be kept secret, revealed only in extreme circumstances. Lightspeed Rescue also had, for the first time, a Power Ranger with no Super Sentai counterpart in the Titanium Ranger, as there was no regular sixth ranger in GoGo V. Also this is the last known Power Ranger series where the main villain of this series was also the main villian in it's Sentai counterpart.

Lightspeed Rescue takes place in the fictitious city of Mariner Bay, California, which was built on an ancient demon burial ground. When the demons threaten to rise again, a government organization called Lightspeed, headed by one Captain Mitchell recruits four civilians and his own daughter to defend the city. Each of the four civilians chosen had a special area of expertise: Carter Grayson, the Red Ranger, was a fire fighter in the local fire department; Chad Lee, the Blue Ranger, worked as a lifeguard and marine animal trainer at a local marine amusement park; Joel Rawlings, the Green Ranger, was a stunt pilot; and Kelsey Winslow, the Yellow Ranger, was an extreme sports athlete. The five Power Rangers were aided by a team of scientists and engineers led by Miss Angela Fairweather, and operated out of the Lightspeed Aquabase, an underwater military compund that also served to deter the hydrophobic demons from attacking the base directly.

The five Rangers would be joined by Captain Mitchell's (long thought to be dead) son, Ryan. Together, the six Rangers would prevail against the demon forces time after time, culminating in a final showdown where, in the Power Rangers tradition, much of the weapons and other equipment that was used by the Power Rangers over the series was destroyed.
