Sledge is one of the main antagonists of Power Rangers Dino Charge and Power Rangers Dino Supercharge. He is an intergalactic bounty hunter who wishes to obtain the Energems and use their power to conquer the universe, but is opposed by the Dino Charge Power Rangers. He orbits the Earth onboard his spaceship, joined by his generals Fury, Wrench, and Poisandra (who is also his fiance). His monsters are in actuality the outlaws he has captured during his years as a bounty hunter, to who he promises freedom if they manage to retrieve the energems for him. Whenever they are destroyed, he fires an energy blast dubbed the Magna beam down to Earth that fired from the Magna Cannon installed on his ship, reanimating it and causing it to grow.
In Power Rangers Dino Supercharge, it is revealed that he was not coveted the Energems for himself, but rather his employer Lord Arcanon, a powerful alien whom entrusted him the job to turned all outlaw monsters into his army. Sledge finally decides to eliminate Arcanon.
65 million years ago, Sledge attempted to steal the Energems from an alien known as the Keeper, eventually shooting him down over planet Earth. Surviving the crash, Keeper entrusted the Energems to various dinosaurs for safekeeping, and tricked Fury in to bringing a bomb onboard Sledge's ship. The resulting explosion sent Sledge and his crew careening off into space and releasing all of the asteroids Sledge had collected, leaving Fury stuck on Earth while the asteroids impacted the planet, causing the extinction of the dinosaurs.
Power Rangers Dino Charge
Sledge returns in the present day to once again claim the Energems for himself, only to find himself opposed by the Dino Charge Rangers, a group of teenagers founded by Keeper who fight and defeat the monsters he and his generals release into the world, as well as finding the Energems before Sledge. Eventually, Sledge, fed up of Poisandra's constant nagging, has Wrench create Curio in order to keep her occupied while he and the other generals focus on retrieving the Energems.
In season finale, he managed to acquire the Purple and Red Energems as well as capture Keeper, but this resulting the final battle that crashed his ship and costed him his worst monster, Greenzilla. The resulting crash and damages that the heroes caused made him presumably killed, but in reality he survived (albeit wind up separated from the others during the crash) and biding his time for return.
Power Rangers Dino Supercharge
His temporal absence was allowed Heckyl and Snide to temporarily taking over the leadership of his minions. Instead of immediately goes to retake his position, Sledge, whom discovered a batch of Greenzilla's eggs, six in all, decided to spread the eggs all over the planet whilst keep in touch with Heckyl to be in charge on his crew until Lord Arcanon arrived on Earth. Also, due to boredom from his duty on his ship, he briefly relaxing on Earth.By the time he returned for his crew and revealed to Lord Arcanon that he fed up from worked for him, Sledge took the dark Energerm for himself and use it to destroy Arcanon and Singe, as well as Conductro and Screech. Finally reunited with his crew, and allied with Snide now, Sledge regained control of his ship with some plans to destroy the Earth. He sends Badussa against the Rangers to gain the time to repair his ship.
In season finale, Sledge causes his own demise : he betrays Snide, in offering the Dark Energem to Poisandra instead of him (as gift of wedding) and wants to send him on a suicidal mission against the Rangers without knowing that Snide has heard all. Later, after his six Greenzillas were destroyed, he refuses to send the Magnabeam to Snide, chocking Wrench, and Snide is destroyed by the Rangers and Heckyl. Then he uses the Greenzilla's eggs to deploy his magnetic nets to send the Earth in a space discharge and take over the Energems. To stop him, the Rangers destroy the Dark Energem, with the help of all humans and Sledge is killed with his crew when they are sucked into a Black Hole.
In the final battle in the past, between Sledge's Crew and the Rangers, Sledge fights the Rangers (Shelby, Chase, Riley, Koda and Ivan) with Fury and the Vivixes. Fury gives him the container with the remaining Five Energems, but Tyler who rejoined the fight has replaced the Energems by the Guardian's bomb. Sledge comes out narrowly but Fury is killed by the explosion. Devastated by Fury's death, Sledge uses the Magnabeam and beats the Rangers and the Guardian. He is about to crush them when Heckyl capture him with his magnetic nets and Sledge is finally killed with the rest of his crew when Heckyl leads his ship into the Sun.
- Sledge is perhaps the oldest Power Rangers villain as he was alive when the Dinosaurs died out, making him at least 65 million years old(though this actually had something to do with his life that mostly spent in the outer space).
- Sledge is created exclusively for Power Rangers and has no direct Sentai counterpart to speak of. He is the first villain with this distinction since the Venjix Computer Network from Power Rangers RPM.
- Sledge is not the first Big Bad of a Power Rangers series having a group of monster minions whom have a notorious reputation as outlaws, as Ransik had recruited a group of mutant outlaws as his minions.
