[Sentai]

There was nothing wrong with alot of the Disney series'. Jungle Fury was near perfect, Mystic Force I wouldn't change one detail, Dino Thunder was great, and SPD couldn't have been better. And RPM was an amazing season. What hurt it was the fact Disney gave up and it was on at an impossible timeslot. That just leaves two I would change. Ninja Storm and Operation Overdrive.

The name I'd leave alone. Ninja Storm works, and the theme was good to. The actors I'd keep, even turning their mentor into a guinea pig. I like guinea pigs.
What I would change is some of the story elements. For one thing you'd never see Lothar's annoying neices or Cyber-Cam. That I promise you. Cam would still become green and in the same way, because that story arch I actually enjoyed from start to finish. One thing I could change is the Thunder Rangers. I'd play them up more as rivals. Working together only when it suited. They wouldn't be evil, they just wouldn't care. I'd also play up more with the whole rival school angle to. That wasn't used near as much as it could've been.

Operation Overdrive though needs a complete overhaul from top to bottom. Starting with the cast. Yellow can stay, but the rest of them (Especially Black) can go find work elsewhere.
Power Rangers: Relic Hunter. It fits what the storyline was much more than Operation Overdrive. Overdrive might've worked for a season like Turbo, or RPM, but not Boukenger. I'd keep the villians the way they were, but I'd back them up to only two. Ice Man and Fire Dude. Yes, I forgot their names. Sue me
They would still be brothers and still be after the Great Treasure. But they'd also still be rivals until the very end.
This is how I see it playing out.

Millions of Years ago a Great Knight, Sentinal Knight, created a Relic with the power to shape Dreams. Knowing that the power could be used for terrible purposes he creafted himself armor granting him eternal life to protect the Relic. But Evil found the Relic. Frostion and his brother Infernion found the Planet where the Relic was being guarded. Knowing he could not beat them both, Sentinel Knight froze himself and the Relic in stone as the planet was destroyed around them. Hurtling them through space..
The Sentinel and his Relic have slept through the Eons upon this new Planet of Earth. And are now Museam Pieces. But Frostion and Infernion have never given up their search. Sensing them approaching, Sentinal Knight forces himself awake from his slumber. But the Eons have drained his energy leaving him stuck within the shape of a sword.. A sword found by Museam researcher Trent. Trent grasps the sword, trying to determine the meaning of the symbols on the side when a great light over comes him.. And he finds himself face to face with Sentinel Knight. SK bestows upon him the power of the Relic Hunter. Tasking him with finding others to help protect the Relic and the others blown through space when his planet detonated, before Frostion and Infernion can use them for great evil.
Using the Sword as a power source Trent calls upon four others with brave hearts, turning simple machines into their Relic Drivers. Using their powers combined to form the powerful Relic Megazords and defeat evil as the Power Rangers Relic Hunters!
