1 Goku, Gohan, Goten, Bardock, Turles and Goku Jr. - Dragon Ball (Z / GT)
Of course Goku, Gohan, Goten, Bardock, and Goku jr. look alike! They're related. It would make more sense to compare anime characters from another anime that may look similar to Goku instead of comparing him to chatacters in his own family or show. It's like saying that me and my bro look alike. People would be looking at me like I was stupid. But if I said that my bro looks similar to Kuwabara from Yu Yu Hakusho then that would get a better response and we could debate over why he does or why he doesn't. Coincidently my bro wore his hair similar to Kuwabara in high school and I called him that all the time..he hated it.
They're nigh identical!
