Because back then, the story was framed more as adventure story, so of course it followed the main character around more than the others. In fact, the Pilaf arc made Toriyama realize that Goku's character kinda got overshadowed by the louder and more colorful presence of Bulma, Yamcha and Oolong, so he made them split. Not to mention that Goku's immense strength was more or less part of a joke, that he was this odd, callow, were-monkey boy that could learn ki techniques which took fifty years to master by watching it once. King Piccolo was the first real threat the story ever had, and yeah, he was given exclusively to Goku.GTx10 wrote:Has nobody watched Dragon Ball? (The Kid Goku stuff) I ask this because a lot of people complain about Son hogging the spot light when Dragon Ball (Kid Goku stuff) had whole arcs dedicated to nothing but Goku. Does the Red Ribbon Arc not ring a bell for anyone or how about Son Goku being the only viable threat to Demon King Piccolo? So my next question is if "original" Dragon Ball shoved Son Goku down our throats why is it suddenly a problem during GT and Super?
My guess is because folks may not like Son Goku and thus any time he is on screen people bit@h. Is that what it boils down too?
However, this changes once DB takes a clear and definite turn from the adventure genre to straight-up action. The cast gets bigger, Toriyama feels they're good enough to carry the story instead of Goku for long portions of the story, even have them surpass Goku on occasion. Z part of DB is what people love most, and that part was generous in sharing it's screen-time with the other characters.
