Aeralfos

Aeralfos are a special variety of Lizalfos, having the ability to fly, and they carry shields and swords. Their shields have Clawshot designs on the front.

There are three in the City in the Sky, two in the Cave of Ordeals and one in Hyrule Castle. One from the City in the Sky appears as the dungeon's mini-boss, all the other Aeralfos are enemies and are easier to defeat than the mini-boss.

Battle
The first battle with an Aeralfos is in the City in the Sky. Here, it acts as the mini-boss. Unlike the other battles, this Aeralfos has the ability to fly out of the room and back in. The main weapon in the battle is the Clawshot. When the Aeralfos is preparing to attack, it puts its shield up, which for some reason has a Clawshot design on it. Using the Clawshot at the right moment brings the momentarily stunned Aeralfos hurtling towards Link. The sword is then used to defeat it.

However, when it recovers, it jumps away. If it is still standing on the ground, the Clawshot can be used, but it brings Link towards the Aeralfos, not the other way around. This gives the flying lizard a chance to attack Link with its sword. The other battles with Aeralfoses are much like this one. In the Cave of Ordeals, the two Aeralfoses are joined by a Darknut.
