Enemy Ideas

I'm not sure if this has been done before, but here goes. This topic is for, as the title states, designing your own enemies. Please provide the name of the enemy, a description of the enemy, any weapons the enemy wields in battle, and whether it is just an enemy, a mini-boss, or a boss. If it is a mini-boss or a boss, you may list the reward(s) you would have be obtained for defeating the enemy if you could bring them to life. Finally, if you use an enemy that has already been used in a Zelda game, it is only acceptable if you have added to it in some way. I have no ideas right now, but I will come up with some sooner or later.

There was a thread like this, but it's probably outdated by now. Here's the enemy I posted in that thread.

Name: Dragolfos
Difficulty: Challenging
Status: Miniboss. It appears as a miniboss in a couple times, but only one time do you get a weapon/item for defeating it. And that's the Knight's Cape.
Weapon: Long sword with wavy blade
Description: A dragon-like creature, as its name suggests. It has wings, scaly skin, and sharp teeth. However, instead of breathing fire, the Dragolfos has a habit of breathing gas that can put people to sleep. Though, that ability isn't used often, since the Dragolfos would rather fight and kill its opponent. The Dragolfos wears plenty of armor, and the only attackable areas on it are its legs and its tail. Its body is a dark green color and its eyes can be either golden or navy. The Dragolfos also has sharp claws on its fingers and toes and tiny spines going down the center of its back and tail. It also has dragon horns on its head. The creature is quite fierce looking.
Attacks: The Dragolfos can use its sword to attack, its claws, or fly into Link with its wings. It could also use its sleeping gas, but it rarely wants to. Still, with the attacks it already uses often, it makes a tough fight. Which means it's also difficult to defend from.

There. Feel free to comment! ^^

Something like The Flood but magical and not so devastating.
