I'm not sure who'd win in a fight, but I know that I could never fully control the wolf while he was attacking, which was especially annoying on spiral staircases.
Depends... if midna got off the wolf and fought next to him then its possible. Would make wolf faster, would make it so midna could use ALL her spells (if u listen near the beggining it turns out she knows alot more spells then she shows =D she even noes some of gannondorfs weaker moves.) but then again norlmal link could use the broken mirror and just temporarily get rid of wolfy... then again the twighlight sorta disapears after so hmmmm... Id say Normal if he was using his Bow and hiding like a bich XD
