He is a poacher who captures rare animals and sells them, usually for their hides. Truy cruel, he clearly enjoys killing animals, at one point even singing a twisted version of the song "Home on the Range". He is an excellent hunter and tracker, and although he has only a third grade education (which he considers to be an accomplishment on his part), he is very cunning, able to lie and cheat effectively, also quite cunning, tossing Cody's backpack into the water so that he will be presumed to have been eaten by crocodiles, coming up with the plot to trick him into leading him to the eagle, and being aware that Cody will never believe he is just letting him go out of the 'goodness of his heart', maintains a nasty demeanour even as he releases him.
He has, for some unknown reason, chosen NOT to kill his pet lizard, whom he calls Joanna, and although he threatens her on several occasions it is always when she misbehaves or does something stupid.
At first glance he does not appear healthy. He seems to be balding, sports a pot-belly, and is tall and quite lanky despite the gruelling nature of his job. However he is actually quite strong, able to fight off several saltwater crocodiles, which are considered among the most dangerous animals in the world.
