Definitely the cucco's revenge squad. Appearing in A Link To The Past, Ocarina Of Time, Phantom Hourglass, and Spirit Tracks, this is the coolest and my most favourite enemy. After hurting a cucco a few times, a large group of indestructable cuccos appear ready to tear link to shreds.
Darknut from Twilight Princess great enemy to fight. One of the few real sword fights you experience until Skyward Sword. It was an enemy you could fight in multiple ways including hidden skills which was awesome.
I think it's obvious. IRONKNUCKLES form just about every Zelda game! Especially form Ocarina of Time. They are SUPER fun to fight, post a tough fight at times, and look awesome. They are just awesome enemies. If they were real, I would want them as my best friend.
I enjoyed fighting the Lizalfos in Twilight Princess because they were one of the few humanoid enemies that you could actually use special hidden moves on without killing them before you can finish. It was fun to pull off all of the cool combos that are possible in Twilight Princess, and the Lizalfos were one of the few enemies where this was actually possible. They also looked quite neat, with their fairly realistic design. They are also a staple for Zelda enemies, so it was nice to see them return in this form for Twilight Princess, and then later Skyward Sword.
ReDeads from Legend of Zelda : Ocarina of Time and Twilight Princess , because even tho i've seen them 10000 times , i still get pretty scared and i still shiver when i hear them scream. I especially get nervous when i'm low on hearts and he "hugs" me , so i start spamming my buttons as fast as i can.
