A single punch from goku can literally kill the gorgon for all saying "all we need is a gorgon" "Atheon opens the timestream" goku will teleport out. And he would probably destroy Atheon before he even does the timestream thing. Crota's oversoul vs spirit bomb or kamehameha. Goku will just pick up crota and toss him over the edge. Or super saiyan punch him to death. Just my $0.02
