The show follows the Power Rangers Tyler Navarro (Brennan Mejia), Shelby Watkins (Camille Hyde), Koda the caveman (Yoshi Sudarso), Riley Griffin (Michael Taber), and Chase Randall (James Davies) who protect the Earth from the evil alien bounty hunter, Sledge, who seeks the Energems to become invincible.
The Power Rangers are later joined by the medieval knight Sir Ivan of Zandar (Davi Santos), his modern liege Prince Phillip III (Jarred Blakiston), their own tech expert Kendall Morgan (Claire Blackwelder), Tyler's long lost father James (Reuben Turner, Dan Musgrove), and Keeper's apprentice Zenowing who also become Power Rangers to stop Sledge, only to find his former prisoner Heckyl (Ryan Carter) has transformed into the more powerful evil alien Snide and he now wants to finish what Sledge has started and take over the Earth.
As the spirits of dinosaurs that Keeper initially entrusted the Energems to have bonded into them, they manifest as Zords that the Dino Charge Rangers use to fight enlarged monsters.
He also works to find his missing father, who mysteriously disappeared ten years prior to the series while at an archaeological dig site and left behind a journal containing a sketch of a monster.
[12] Mejia spoke in interviews of how he and the other cast members trained with Japanese stunt actors from the Super Sentai series to prepare for action scenes.
[14][15][16] Shelby Watkins works as a waitress at the Amber Beach Dinosaur Museum's restaurant, the Dino Bite Cafe inside.
Though she comes off as clumsy and ditzy due to disliking her position, she is a stubborn and noble tomboy with a vast knowledge of dinosaurs, with her favorite being the Triceratops.
However, as the team bonds, the two learn to work together, and Shelby is able to impress Dr. Morgan by applying her dinosaur knowledge to the fight against Sledge, such as building a device to locate the Energems and creating the Spino Zord.
She also spoke of how the young fans have treated her when they realize who she is, bringing up a time she was recognized by two little boys in a pizzeria in her hometown of Washington, D.C.[12] While filming in New Zealand, Hyde received martial arts training and continued to pursue her academics through online courses.
[13] Koda is a virtuous Neanderthal caveman who found the Blue Energem a hundred thousand years prior to the series in a Stegosaurus fossil.
After saving his little brother, Taku, from a smilodon, he fell off a cliff and ended up frozen in a glacier, though the Energem's powers kept him alive.
By the present, Koda is found and unfrozen by Chase and Dr. Morgan, and slowly adapts to modern customs and technology, speaking in broken, minimalist sentences.
[14][15] Chase Randall is a laid-back and flirtatious young man from New Zealand who works at the Amber Beach Museum as a janitor and expert digger.
[26] As the Dino Charge Black Ranger, Chase is skilled at firearm-based combat and wields the Para Chopper beam gun.
[27] Kendall Morgan is a confident, direct, and blunt scientist who manages the Amber Beach Dinosaur Museum and serves as the head of its paleontology digging group and technical advisor to the Rangers.
While escorting the young Prince Colin, Sir Ivan found the Gold Energem, but was attacked by Fury, who absorbed him and kept him prisoner.
He directed a Tyrannosaurus to gather several dinosaurs and other ancient creatures to bond with the Energems to keep them safe and tricked Fury into taking a bomb to Sledge instead.
[34] While traveling back in time to save the Earth from the black hole, the Rangers encounter a past version of Sledge before sending his ship and everyone aboard flying into the sun, killing them.
[34] While traveling back in time to save the Earth from the black hole, the Rangers briefly encounter a past version of Wrench and kill him.
[38][29][39] Having captured the former as of the present, Fury rejoins Sledge and continues his attempts to steal the Energems for him,[31][26][40][32] despite losing control of Sir Ivan after the Rangers free him.
[9] Poisandra is the vain, air-headed, heart-themed fiancé of Sledge who only cares about marrying him, with his goal to claim the Energems upsetting her greatly.
[34] While traveling back in time to save the Earth from the Black Hole, the Rangers briefly encounter a past version of Poisandra and kill her.
[9] The Vivix are Sledge's paramecium-themed foot soldiers who can merge with each other to form large monsters called Vivizords to fight the Rangers' Zords.
[9] Heckyl is a humanoid alien with the ability to fire energy blasts from his hands from the planet Sentai 6, where he was transformed into the monstrous ammonite-themed Snide upon touching the Dark Energem while he was protecting it from Lord Arcanon.
[28][33] Heckyl also enacts a separate plan to obtain the Energems by befriending the Rangers and infiltrating their ranks, only for them to discover his true intentions and connection to Snide due to his inability to control when his transformations occur.
[44][45] After Lord Arcanon arrives on Earth,[46] Heckyl is re-incarcerated, but has Poisandra free him in exchange for telling her Sledge's true fate.
[9] Lord Arcanon is a power-hungry, ruthless, calculating, multi-faced Statue of Liberty-themed intergalactic warlord who hired Sledge to capture outlaws for him in order to build an army to help him rule the universe.
He arrives on Earth ostensibly to join Heckyl and Snide while secretly reporting back on their activities to Lord Arcanon, developing a rivalry with a distrustful Fury in the process.
Doomwing is a cocky and manipulative Archaeopteryx-themed alien, servant of Lord Arcanon, and the evil half of Zenowing created from the Dark Energem.
The Rangers build and use a split emitter to separate Zenowing from his evil side, allowing him to return to Keeper and warn him of the Dark Energem.
