John Carter, Warlord of Mars

John Carter is a Virginian member of the Confederate Armed Forces, mysteriously transferred from Earth to the dying red planet of Barsoom, an analogue of Mars. Barsoom is home to a myriad different races of Martian.

Powers
On Barsoom, the lighter gravity makes John Carter immensely physically strong compared to some of his foes. John Carter is also, at least according to his own narrative, in superlative physical condition, and the greatest swordsman in two worlds, unwilling or unable due to the simple facts of the matter to acknowledge any other swordsman his superior or even equal.
