Can't go wrong with Chrono Trigger :D
Realistically Link doesn't stand a chance against Crono, i mean common seriously...
Crono is not only an extremely skilled swordsman but he also has control over lighting. Combining the two Link wouldn't stand a chance.
Link has proven to be pretty damn slow too, whilst Crono fights at a pretty fast pace.
Crono wouldn't be able to defeat any of the DBZ characters though; they're god like something which Crono is not.
