It would be awesome if Link had a set of Sheikah gauntlets he could use for punches. Obviously decreased defense with no shield but explosive offensive power.
The ability to drink an elixir to temporarily infuse elements to them would be sweet.
Depends on the Link probably... The one from TP does sumo wrestling. Link as a character overall is pretty stealthy, flexible, and quick to reflexes. I guess yes and no, it depends on his opponent. He's not very strong in terms of muscle power.
