"Power Rangers Dino Supercharge" was trademarked by Saban Brands in 2014 during the run of Power Rangers Super Megaforce. The season was formally announced via press release on June 8, 2015, with the minor name alteration to "Power Rangers Dino Super Charge".
"Long ago, an alien named Keeper entrusted the greatest power in the universe to dinosaurs. Millions of years later, the Energems were found, and the evil Sledge fought ruthlessly to steal them, until the rangers finally defeated him. But, from the ashes a new threat arose... Only one team of heroes can stop him; Power Rangers Dino Super Charge!"

"Long ago, the evil Sledge tried to steal the greatest power in the universe. But an alien named Keeper entrusted them to dinosaurs. Later, the Energems were found, a team of heroes use them to defeat Sledge and keep the world safe, they are Power Rangers Dino Super Charge!"
―Christmas Opening narration[src]
The Dino Charge Rangers disband after defeating Sledge, but their job isn't done just yet. One of Sledge's most dangerous criminals, Heckyl, and his alter ego Snide, are aiming to pick up where Sledge left off and harness the power of the Energems to rule the universe. With new weapons, new allies, new zords, and the new T-Rex Super Charge mode, the Rangers are ready to settle the score against one of their most dangerous enemies!
This marks Power Rangers Dino (Super) Charge as the second Power Rangers series to be set in an alternate universe since Power Rangers RPM.
This is currently the only "super" season in which the titular power-up is not used by the whole team; the Super Charge mode is exclusive to Tyler.
This is of course, not counting Dino Super Drive which is in fact used by all 10 Rangers.
Counting Dino Super Drive, the next "Super" season, Super Ninja Steel, is similar to Dino Super Charge in that a cockpit mode is the titular "Super" mode but one of the Rangers (Red in the case of Super Charge and Gold in Super Steel) gets their own individual "Super" mode. Breaking this difference, is the Rangers' arsenal and Power Stars being made of Ninja Super Steel which makes their powers in general be the "Super" aspect of that season.
It is also the only one that does not debut in the first episode.
