Favorite Version of "Goku"

Might sound typical, but DBZ. Goku truly was at his pinnacle in terms of personality which he kept his innocent nature from Dragonball, but was also shown to be competent in handling situations in a seemingly pragmatic manner. He was an adult in Z; not at all like the goofball they sometimes portray him as in Super. He was also compassionate; giving his (then) enemies chances not because he was naïve, but because he had faith that they could become better people someday(and so that they can later, you know, have another fight ).   

Finally, he was supportive. The quote that he says to Gohan (original dub aside) in the Time Chamber/ROSAT is some of the best in the series.
