Originally published in 1911, A Princess of Mars is the first appearance of John Carter. A Southern gentleman who is transported by mysterious means from the Arizona desert of the Old West to the surface of Mars. In no time at all Carter is facing 12 foot tall, green-skinned, four-armed, Martians riding immense six legged beasts with mouths full of fangs. The vicious and warlike green Martians are armed to the tusks with swords, spears and deadly radium pistols. Carter discovers that, on Mars, he now has superhuman strength and agility, including the ability to leap vast distances with a single bound. In short order Carter is taken prisoner but defeats several of the huge Martians to become a warrior amongst them.
