He's trying real hard to be one of the good guys.
I just read A Princess of Mars and I suppose I'll probably see the John Carter movie soon, so I've been thinking of martian plots, themes, and characters (with a focus, of course, on roleplaying in the setting).
- Earthlings randomly get transported (astral project?) to mars sometimes (is this ever explained?). Do people from stranger places ever end up there?
- Martains have some way of viewing planets all across the universe, and all planets with the right environment have humanoid life.
- Gravity difference means earthlings are unusually strong and agile on mars, once they're used to it. Carter is good at fighting because he was a fighter on Earth, but others would presumably be good at other things.
- Martains are telepathic and have machinery that's controlled by telepathy.
- Earthlings and better then martians at telepathy, once they learn how.
- Dangerous wildlife, but some of it will become loyal companions when treated with respect and affection.
- Martains in general are convinced that they have no time for kindness, but many of them still respond positively to it.
- Men don't kill women, and vice versa, so an army (or group of assassins) needs both if they're going to face (target) both.
- Martian women get kidnapped ALL THE TIME.
- There are two extra "rays" of light on mars, one that can be used for flight and another that can be converted to atmosphere.
- Martains lay eggs with a loooong gestation peroid.
- Martain live for a long time.
- Some Earthlings also inexplicably live for a long time (is this ever explained?).
- People that maintain the atmosphere machinery are exempt from usual war and politics, and have a sort of diplomatic immunity.
