Opinion
1) Where I think this psychoness comes from:
As the older brother of the two, Ron is the one that creates the plans for their next mission, and he always makes his plans so that only two (Ron and Harry) come out on top. Before the McDougall brothers ever crossed paths with the infamous outlaw, Gene Starwind, Harry has always been able to get what he's wanted, and since he's older brother never really taught him that not everything will go your way, Harry will go psychotic (I like it when he goes crazy. ^_^) every time he doesn't get what he wants.(I guess he and Dilandau can become friends quit easily.) For example, when Melfina refuses to go with him, Harry goes into a rage and winds up thrashing the roses in front of her face.
2) My opinion on Harry has a person:
Personally, I believe Harry is one of the better developed characters from Outlaw Star because he displays so much more emotions then all the other characters; love, pain, sincere, craziness, etc. Also, I have to admit that he's also quit admirable because in the series he's beaten by Gene like five different times and is still willing to fight on. *fan-girl has been released* Finally, Harry is EXTREMELY KAWAII!!!! ^_^
3) Harry's Blood type
In Japan, people believe that your blood type will determine your personality or the type of person that you'll become. Since Harry has the blood type AB he's know as a humanist which is a person that has an intellectual movement centered around humans. People that have this blood type are great rational thinkers, and they're good critics and analysts, very aware of the world that surrounds them; but they can seem to be cold-hearted and standoffish, sometimes even vain. It's hard to get to know them. They value reason more than emotion, but paradoxically value the feelings of others and try to be useful to them. They often wish to be at harmony with society, but usually feel distant from it. They're sociable, sensitive, brilliant, intellectual, well organized, and passionate. However, they can quickly sink to fighting with others and with themselves, and can be reluctant to use the full extent of their considerable abilities. Well, doesn't that sound close enough to Harry's personality?
