I'm glad this was pointed out, because I've always felt this way. For much of Dragon Ball, Goku wasn't a battle maniac at all. I honestly don't remember many examples of 11 or 12 or 15 year old Goku particularly enjoying fighting outside of a tournament context (the Tenkaichi Budokais being something he of course very much loved). He never shied away from fighting someone, but his attitude when fighting Yamcha or Piccolo Daimao or the members of the Red Ribbon Army was very serious and focused with elements of "Man, I am so pumped up!" creeping in only seldomly. The earliest that I remember the lust for battle kicking in would be... Mr. Popo, maybe, since I don't remember Goku being entirely certain as to the seriousness of the fight, but still getting excited anyway. Before that, I think Goku honestly could have taken or left martial arts were it not for the Tenkaichi Budokais spurring his interest. I think that for much of the original Dragon Ball anime, in the absence of the Budokais Goku would have been content to just return to a life in the wilderness at Mt. Paozu, and that he would have been someone who simply wants a very active life, rather than someone who lives for martial arts specifically.Gaffer Tape wrote:I'm going to go against the grain here, methinks. I'm not a fan of the "hope of the universe" Goku. Even the movie Toei Goku can get a bit outside of the character at times. But I honestly feel the accidental hero, selfish manchild aspect is far too overstated as well. Maybe it's fans pulling against FUNimation's depictions. Maybe it's Toriyama pulling against Toei's depictions. But Goku is (or was at least) very selflessly heroic. I think he, unfortunately, became less so over time as he began inheriting "Saiyan" characteristics that were then claimed to have always been there. But remember this is a guy who abandons his epic quest without hesitation to carry a sea turtle back to his home, with no thought of reward or expectation of fighting, just because it's the right thing to do. He finishes gathering all the Dragon Balls, even the ones he doesn't care about, just to bring an innocent man back to life. Yes, he is driven by battle. Yes, he is simple and is often motivated by his own desires. Yes, he can often make reckless decisions. No, he does not live by an overt code or sit in the Hall of Justice waiting to battle the Legion of Doom. And I love all of those things about him. But that's not all Goku is at all, and it pains me that he continues to be pushed further in that direction as the years go on.
I actually don't personally mind the shift for the most part and like Goku a lot as either a child or an adult, with the exception of the 28th Tenkaichi Budokai where he basically just seems to have devolved into an obsessive musclehead; before that his Z characterization was closer to simply being a very serious and devoted martial artist who made questionable choices whenever the adrenaline of a good battle got to his head. I do think that both the fanbase and newer materials retroactively assign Goku traits that were either absent or vastly less prominent during the early run, though. There wasn't much 'poison' (to use Toriyama's own well-chosen word) to 11 or 12 year old Goku at all, he was an almost perfectly family-friendly child protagonist that rarely if ever did anything very controversial at all and whose actions anyone could get behind as being justified and moral. Goku's vices don't really start coming into play until the 23rd Tenkaichi Budokai.
EDIT: Or maybe it would be more accurate to say that his 23rd Tenkaichi Budokai/Saiya-jin/Frieza saga self was simply "a serious and devoted martial artist who made questionable choices whenever the adrenaline of a good battle got to his head." His flaws became more prominent, but during that time period it was more just for flavor rather than being something that genuinely threatens the audience's feelings towards him. The "Goku, what the hell are you doing?" element of his character doesn't really get cranked up until after Frieza, probably starting with the decision not to take advantage of Trunks' warning, at which point he consistently makes more controversial choices and becomes a more challenging character for the remainder of the story.
