Goku, this cat just blows my mind. He's got it all, a wife, two kids, a few good friends, and an equal oppurtunity job. He's the most powerful being in the universe, and... topping it all off, he's a big dork. He's just good natured to the nth degree, so that whenever something good happens, he's so pleased by it, like, "Hey! That's great!" and when something bad happens, he gets so down. He's also got a terrible problem with getting his ass beaten at the beginning of any new saga in the series. The formulaic plot of DBZ so far has been that Goku gets incapacitated in some way at the beginning of the series, and then he spends the rest of the time training, or healing, or waiting to be brought back to life, while everyone else buys time. Then Goku comes back and wins the fight. Repeat. Repeat. Repeat. And then Gohan grows up.
