1. Link

2. A combonation of magical weapons, such as light, ice, and fire arrows, Din's Fire, Nayru's Love, Mirror Shield, Master Sword, other physical weapons, and the power of the Triforce of Courage make Link an incredibly tough opponent.

3. He is stronger because of his massive arsenal and the ability to repel Clouds sword blows and magic spells.

4. I am very confident because even though each has fought the most pwerful evil of their realm Link has the edge because of  his ability to adapt and the use of some defensive weaponry.
