Jake is portrayed as a typical tough guy, always talking tough to, and about, people he doesn't like (specifically Percival C. McLeach). He's also known to be fearless and at times, sarcastic, showing no fear when facing a giant snake, and laughing at the prospect of Bernardsaving the day (though he changes his mind at the end). However, his heart's in the right place. He cares deeply for his friends (especially Miss Bianca), and proves to be a valuable asset in the film
