Since gritty reboots and reimagines seem to be the all the rage lately, here is my rebooted version of Captain Planet.

Plan-8 is an alien from a doomed world, who crash landed here on Earth.  Seeing the inhabitant of Earth making the same environmental mistakes that destroyed his world, Plan-8 vows to save his new home no matter the cost.  Plan-8 recruits 5 college students from around the world to help him on his Eco Crusade.  Using the technology found on his sentient spaceship, Gaia, Plan-8 is able to harvest the essences of his Eco Crusaders or Plan-8 teers as he calls them, giving him super powers, which he uses to defend Earth.
