@reddsevil34: I try to make less predictable battles with less similar opponents. The Scotsman is a more interesting opponent for Sekiro who was Jack's equal even though their fighting styles were different so I chose him over Jack. Sekiro and the Scotsman still have their prosthetic limbs in common, though.
@endless_dark: I would agree that Saitama would defeat Namek Saga Goku but I also think you're underestimating Goku's physical strength. He punched away an attack from Frieza that flew into space at FTL speeds and destroyed a planet. A casual energy attack from first form Frieza destroyed a planet that was ten times the gravity of Earth and judging by the size compared to the mass it was pretty much like a white dwarf star busting feat. If first form Frieza can do that so effortlessly with just one finger then final form Frieza locked in a battle to the death and angrily charging up and attack with both hands is obviously a hell of a lot more devastating. I don't know if Frieza could "obliterate a star" like Boros' cannon can do according to official sources but Goku punching it away like he did makes him physically superior to Boros.
