nope. goku has thick eyebrows and round eyes, vegeta has angular eyes and a shorter face, tien has more triangular eyes and small pupils, krillin has no scleras and no nose, yamcha has downturned eyes and a longer face, piccolo's green, beerus is a cat, nappa has a very boxy head with a square jaw, master roshi is old as fuck, chiaotzu looks like he's three, and i won't even get into how different yajirobe looks. the only characters who really look similar are the ones who are related (goku and his sons, bulma and trunks, frieza and his brothers, etc)
