One punch man
Well Super Man may have only one weakness but Goku will lose if he doesn't turn into Super Saiyan 1, 2, 3, or 4 Super Man will win for sure but if Goku does Goku will be so powerful that he will definitely win. No problem.
When Android 16 and Goku scale against each other, the Goku is the one that is most likely to win this duel.
goku would win
Its one fight goku wont win. chi chi
If you mean win then Goku would win.
Of course goku be cause he would kill iron man in 1 blast and iron man could not survive such a beam so it would penetrate through is suit and in his body. but if iron man doges his attack iron man can shoot goku while he is still doing his attack and iron man still has all of his suits he has seven suits so he can keep on switching but goku still has his same body. it will be very hard but in the end goku will win cause he can do the spirit bomb
goku
Goku.

goku super saiyan would win for sure.
goku he can destroy the universe
