Pisces Albafica is a Gold Saint and as a result he’s definitely not someone that you want to underestimate. If you make contact with his blood then you will instantly die, at least this is true for many characters. Goku is protected by his aura and at the end of the day he’s also a whole lot stronger and faster than Pisces. There is no Gold Saint who would be able to defeat him in combat. It’s just not happening. Goku wins.
