Mr. O'Hare is a greedy, obnoxious, argumentative and egotistical businessman who typically hates plants and trees, because (according to him) they are a threat to his air business. He is also shown to have the demeanor of an obstreperous mob member, and he also talks about his business like he was running a monopoly (granted he is, but anyone gets the point). He is also extremely disrespectful and abusive towards his bodyguards and others.
