Captain Planet

As mentioned, this iteration of Captain Planet and The Planeteers will be decidedly less cheesy than the originals. The most notable part of this change is the Captain himself, who is now less of an outdated mascot and more of a
terrifying force of nature.Using the mythology of Judaism/Christianity/Islam, Gaia is pretty much God, The Planeteers are her prophets, and Captain Planet is a vengeful archangel of sorts. God could cause plagues and floods to wipe out a problem, but lacked a corporeal form to deal directly with the subjects causing the problem. He could occasionally speak to humans, though this is only ever depicted through very abstract means (Burning bush/talking thunder), and in the same way, Gaia will only ever talk to our characters, The Planeteers, through visions. This leaves Captain with a less central role, as he is in many ways trapped in the rings as a nonhuman entity.
The Planeteers are the ambassador of Gaia first and foremost and are largely pacifistic in their initial approach, though there's a likely possibility throughout the story that we'll just devolve to ecoterrorism. Although The Planeteers are the voice of Gaia and can fight when they need to, it is an uncontested fact that her sword is Captain Planet. His powers in this RP extend further than the original canon's powers -- Instead of having run-of-the-mill elemental control, Captain Planet is a fearsome destructive force capable of creating tsunamis that cover islands, fires that burn as hot as the sun, winds that can reshape earth itself, and so on. His power is equivalent to anything you'd ascribe the phrase "Wrath of God" to, and if you find yourself wondering who would win in a fight between himself and another fictional character, unless the opponent in question is Sundipped Superman or
Garbodor, the answer is probably Captain.
Bear in mind, Captain Planet
is an extension of Gaia, though he still has his own free will. Whereas his Abrahamic counterparts (Azrael/Archangel Michael) relied on their largely Lawful Good religious beliefs as a scale to judge mankind by, Captain Planet lacks any code other than that of nature, which is pretty True Neutral about things. He's generally only summoned as a last resort, as the destruction he's capable of leaves too much of a risk for him to even
exist outside of the rings. If The Planeteers choose to take down an enemy through force, a pollutant-filled factory gets blown up. If
Captain Planet chooses to take an enemy down by force, the factory and everything within a thirty mile radius, schools, orphanages, hospitals and all, are reduced to a single, smoldering crater in a firestorm of biblical proportions. Captain Planet's main concern is the earth -- not mankind -- and when faced with a tough decision, will choose whatever is best for the earth in the long term.
It's worth mentioning that Captain Planet will always attempt to solve a situation diplomatically at first, though his tone and voice are
decidedly less preachy than the original. He definitely isn't human, and this is most prominent in his detached view of humanity and willingness to kill for the planet. He knows that The Planeteers are helpful to his cause and are on his side, though as a being that exists only to be used as a divine mouthpiece or weapon, he and the group aren't exactly friends.
Although he is much more powerful than his original incarnation, he is not without weakness. Pollution significantly weakens him, and is generally as poison to him as Kryptonite would be to Superman. Aside from the usual pollutants, radioactive waste and manmade radioactive material are especially poisonous to him, to the point that it can be used to kill the otherwise immortal being. Keep in mind, though radiation is natural, it is harmful to animals and thus hated by Gaia, which in turn allows it to harm Captain Planet. Though this fact means that there is a thought process involved in whether or not Gaia dislikes something and if it is harmful to Captain Planet or not, just go with it.
