Altair vs Link
Forgive me if this has been done before, but I didn't find any results with the search engine.
No magic
Altair wins. Why? simple:
Link tries to shoot him w/ a bow but altair is too fast.
Link tries to slash at him w/ sword but altair uses the counter attack skill to counter it, knock Link down and use the hidden blade.
Link tries to stay back w/ shield, but Altair uses guard break.
Link tries to use magic, only to realize that he can't.
Link tries to go on top of rooftops and shoot Altair w/bow, only to realize he can't jump because he has no jump button.
Even if he could, Altair = master of roof jumping.
