Tarzan/John Carter: Warlords of Mars #1

Plot

Tarzan of the Apes has fought every manner of man and beast. He has seen every kind of jungle -- from the darkest rain forests of Africa to the concrete jungle of New York -- and faced every kind of horror those diverse landscapes have to offer. But nothing has prepared him for the savage creatures that now surround him, when the Lord of the Jungle finds himself mysteriously transported to the planet Mars!
