Robin may be a spy who has a lot of experience in hand to hand combat, but he would quickly be overpowered by Ganondorf. Ganondorf has dark magic at his side, but he’s also pretty good with a sword. A single strike would take Robin down and we’ve seen how Deathstroke accomplishes this. Ganondorf is like Deathstroke and he’s even stronger when it comes to physical strength. Robin just doesn’t stand a chance. Ganondorf wins.
