Season 1: Dino Charge Sixty-five million years ago, a dinosauroid
alien named Keeper was pursued through the galaxy by Sledge, an intergalactic
bounty hunter bent on acquiring ten magical stones called the Energems in Keeper's care and using them to conquer the universe. Keeper crash landed on prehistoric Earth, entrusting the gems to many dinosaurs for safe-keeping and crippled Sledge's ship with a bomb that left the bounty hunter stranded in deep space. Unfortunately, Sledge's collection of asteroids held in a tractor beam accidentally rained down on prehistoric Earth and ultimately caused
the extinction of the dinosaurs. In the present day, Keeper is found by paleontologist Kendall Morgan and they set up a base under the Amber Beach Dinosaur Museum in the city of Amber Beach. They begin a mission to find the Energems, but five have already been found by teenagers, who use them to morph into the Dino Charge Power Rangers. The group consists of the Red Ranger, Tyler Navarro, an adventurous teen who is searching for his father who disappeared ten years ago on a geological dig; the Pink Ranger, Shelby Watkins, a waitress with a vast knowledge of dinosaurs; the Blue Ranger, Koda, a 100,000-year old caveman living in modern times as he found his Energem in his tribe's cave, and was kept in suspended animation until the present day; the Green Ranger, Riley Griffin, the youngest of the group who is a skilled
swordsman; and the Black Ranger, Chase Randall, a suave and laid-back
New Zealand skater. With these powers, the Rangers fight against Sledge, Poisandra, Fury, Wrench, Curio, and their prison full of monsters in order to find the remaining Energems and protect Earth. As time goes by, the Rangers are joined by additional teammates with additional Dino Zords: the Gold Ranger, Sir Ivan, an 800-year-old
knight from Zandar who was trapped in the body of Sledge's minion Fury and the Graphite Ranger Prince Phillip III of Zandar, the modern day crown prince of Ivan's home country. An elderly man from New Zealand, Albert Smith, briefly becomes the Purple Ranger before abandoning the position due to his fear of monsters - Kendall then takes over as the Purple Ranger. The Rangers seemingly defeat Sledge and his crew at the end of the series and disband, but the human-like villain Heckyl and his monstrous split personality Snide are shown to have survived.
Season 2: Dino Super Charge After being forced to return to action following Heckyl and Snide's appearance, the Ranger team later gets two new members: the Aqua Ranger, who is revealed to be Tyler's missing father James, and the Silver Ranger, who is revealed to be Zenowing, an alien who was Keeper's apprentice in the past. Meanwhile, Singe, a mysterious warrior who arrives on Earth, quickly steps in as Heckyl's number two, much to Fury's anger. However, Heckyl soon grows suspicious of Singe's intentions, forcing Singe to flee. He later returns to Earth with the person who hired him, named Lord Arcanon, who possesses a previously unknown eleventh Energem known as the Dark Energem. Arcanon overthrows Heckyl and briefly serves as the monsters' leader. During this period, Heckyl and Snide are split from each other after Heckyl discovers that Arcanon destroyed his home planet millions of years ago and erased his memories. Arcanon is soon defeated by Sledge, who is revealed to have survived the end of season one. As the result of Heckyl's memories being restored, he gradually redeems himself and eventually decides to team up with the Rangers to defeat Sledge and his allies. The Rangers destroy the Dark Energem, which inadvertently creates a
black hole which consumes the Earth. The Rangers' ten Energems are revealed to be capable of
time travel when brought together, leading Keeper to send them back to the day he crashed on Earth sixty-five million years ago. The Rangers and Heckyl successfully defeat Sledge and his monsters in the past. After their enemies' destruction, the Rangers go their separate ways. The Energems' time travel ability allows Koda and Ivan to return to their own time periods, meanwhile Heckyl allies with Zenowing to prevent Arcanon's destruction of Heckyl's home planet. Once the remaining Rangers arrive back in the present day, they find that the dinosaur museum has become a dinosaur zoo, with the Rangers realizing that because Sledge was defeated before his asteroids ever hit Earth, they have returned to a timeline where the extinction of the dinosaurs never took place. ==Cast and characters==
