How I'd do Wild Force

 The story begins at the location where the Terra Force Rangers had died. Someone stands among the dust of the fallen warriors, and sends out energy to the dust, creating several orbs. The orbs all vanish in a flash of light. 5 individuals are seen receiving orbs (one each). A radical environmentalist (Taylor), a park ranger (Danny), a veterinarian (Alyssa), a marine life conservationist (Max), and an urban wildlife relocation specialist (Cole).

The five would hear a voice that tells them to meet up at a specific location. They arrive at the Nexus of Gaia (seen in my Terra Force post) and meet what looks to be a child but is really an ancient god, named Animus. Animus is the god of all animals. He's one of the children of Gaia, the goddess of Earth. He says that the 5 have been chosen to be his champions in a battle against the Orgs, evil creatures that are created from pollution, both natural and man-made. The Orgs have recently seen a surge in activity, since a prophecy of the return of their master is seemingly coming true.

The 5 become the Wild Force Rangers. While other teams were focused on helping people, Wild Force is solely focused on destroying the Orgs, once and for all.

There would be episodes that focus on developing the individual rangers, which would have them find new Wild Zord orbs, just like in the show. The zords would be revealed to be descendants of the Terra Titans, and their power orbs are powered by the Terra Force powers that remained in the dust.

Some backstory that would be revealed about the rangers: Taylor is a former Air Force pilot who left when she found out about the damage the usage of jets does to the planet. She decided to focus on environmentalism. Danny has always been in love witj nature, and used to get into fights with people who would spray paint the boulders at a local national park. So he dedicated his life to fighting such things on an official level. Alyssa has always been a nurturing person and cared for animals, so she became a vet. A whale once saved Max from a sea lion attack, and since then he's worked on helping endangered marine life. Cole was always intrigued by wildlife but hated when they were being hurt by urban development. So he started to work to trap wildlife that was being hurt by cities and relocate them to safe places in the wild.

It's revealed that these reasons are why Animus chose them. He knew that their hearts were focused on the planet and animals. 

Master Org would reveal himself and his generals. Zen Aku, one of the generals, would stop during a fight with the rangers and retreat. He would soon be seen attempting to kill Master Org. It would be revealed that he retreated because the rangers mentioned Animus. Zen Aku was friend with Animus, millenia ago. He was the only Org who ever showed care for the planet. He would struggle with the fact that he was born of pollution but loves the planet. He would join forces with the rangers and become the silver ranger.

Master Org would be enraged, and so he'd begin empowering even the lowest of Orgs, so that destruction could increase. The rangers would come close to defeat, but Animus would turn himself into energy and give the rangers a boost of power. With this they would kill Master Org and his generals. That would just leave the regular Orgs, but they wouldn't be as active without the hope their Master brought. Zen Aku would vow to defeat them all and the other 5 rangers would return to their normal lives.
