Here's what Dynamite Entertainment's character biography of Jungle Girl has to say about her:
While Jana has no superhuman powers, she does have several abilities that have helped her survive in the jungle. She's a strong fighter, a skilled acrobat, and a skilled hunter and tracker. Jana is familiar with most of the plant and animal species in the jungle and is fully aware of what they can do. According to the adventurers, she also has amazing reflexes."According to the adventurers, she also has amazing reflexes"? Wow. Did they really say that? It's also not clear from her outfit where she actually carries those several weapons, though.
Jana carries several weapons with her at all times, such as her spear, her hunting knife, and a vine rope. Jana also seems to be able to communicate with several of the animals in the jungle, including the woolly mammoth, which she rides in order to fight a finback.
Alas, Jungle Girl does not have much of a Wikipedia entry; much of it appears to have been pilfered from the aforementioned character biography. You'd think that someone would have come along by now and noted the implications of the character or the fact that it is not an example of attempts by the comics industry to broaden its base of readers. Oh, well.
