I like Goriyas for some reason, either because boomerangs are really cool, or they're pretty fun to fight in Zelda II. Such a shame they completely disappeared after Zelda II though...every other enemy in the game came back, and Goriyas just died...I think they had a lot of lost potential.
Gyorgs are a bit nostalgic for me though, since they scared the crap out of me when I was younger playing Wind Waker. I especially hated going from Greatfish Isle to Windfall during the storm, which takes you right past Tingle Island, and we all know what lurks in those waters. I usually had my older sister play those parts of the game for me, they scared me so much. And the MUSIC that plays when they emerge, my God...These guys have those silly Seahats beat by a long shot, at least they don't suddenly emerge from the water when you don't expect them or chase you all the way across the Great Sea if they can until you kill them or enter a building. Gyorgs are the stand-alone reason why I lacked the courage to 100% Wind Waker until just a few years ago.
In Twilight Princess, I have a hell-of-a-time wiping out all those mounted Bulblins above Kakariko Village in Hyrule Field. Who doesn't love blowing them up with bomb arrows?
