Dinolfos

Dinolfos, also referred to as Dinafols or Dynalfos, are recurring enemies in the Legend of Zelda series. They are anthropomorphic lizards clad in partial body armor. They use short daggers and their ability to breath fire to attack their prey. They are relatives of the Lizalfos race, but are both tougher and more agile.

Dinolfos can be defeated by using the shield to defend oneself against their attacks, and retaliating during the short period of time afterwards, during which they are momentarily stunned. Openings in their defense can also be found and used against them, all the while using the shield to guard. Once struck with a sword, they will sometimes retaliate by breathing fire, depending on the game.

The Legend of Zelda: Ocarina of Time
Dinolfos appear in the Gerudo Training Ground and Inside Ganon's Castle. Unlike their later Terminan counterparts, they cannot breathe fire.

The Legend of Zelda: Majora's Mask
Dinafols breathe fire in this installment and they wield a longer weapon shaped like a scythe. A Dinolfos guards the Hero's Bow in the Woodfall Temple serving as the game's first proper mini-boss. A pair encountered in Snowhead Temple hold Stray Fairies, and a trio of Dinafols are fought in the Secret Shrine. Also, one more blocks a doorway at the Moon.

The Legend of Zelda: Twilight Princess
Dynalfos are found throughout Hyrule, most notably in the Cave of Ordeals. These reptilian enemies are far stronger than the closely related species, the Lizalfos, being larger, more powerful and possessing more armor. Link can use a variety of techniques to dispatch Dynalfos; one is to continually use the Shield Attack on them, followed by the Helm Splitter. It is also effective to strike them with a Bomb Arrow, but this only works if they have not noticed Link. The Ending Blow is difficult to perform against Dynalfos, but not impossible. Since they are well-armored, the most effective attack is the Mortal Draw, because it can instantly kill them. However, the Mortal Draw does not always work since Dynalfos can sometimes block it with their shields. The Back Slice can also be effective against them.
