Blazing Bat

Blazing Bats, also known as Firebats are Ganon's main method of attack in A Link to the Past. They are summoned during the final battle against him during all of his magical attacks, usually brought to life by his Trident. They also make an appearance in Link's Awakening.

A Link to the Past
In A Link to the Past, almost all of Ganon's most powerful attacks utilize Blazing Bats in some manner. He will first create these beings by twirling his Trident, forming eight small fireballs in a circle, which will spread out then transform fully into Blazing Bats one by one, swooping at Link at high speed. Later in the battle, Ganon is able to launch single bats either directly at Link or in a circular pattern, each bat leaving a trail of flames in its wake. Blazing Bats are one of the strongest enemies in the game; if Link is not armed with the Red or Blue Mail, these bats will cause four hearts of damage. They are also entirely invincible, and cannot be stopped, only avoided.

Link's Awakening
In Link's Awakening, the Shadow of Ganon will use Blazing Bats in a similar manner, reprising his attacks from A Link to the Past by using his trident to summon a swarm of six, though they do considerably less damage.

A Link Between Worlds
In A Link Between Worlds, Yuga Ganon utilizes blue colored Blazing Bats. Whenever retreating into his painting form, Yuga Ganon will fire the Blazing Bats out of the walls. Like in A Link to the Past, the bats are invulnerable and must be avoided.

Trivia

 * Ganon himself was able to turn into a huge bat in A Link to the Past, which had a similar appearance to these enemies.
 * Although Ganon has not used these bats in later appearances, the first floor of Ganon's Tower in Ocarina of Time has seven Fire Keese, possibly as a reference.
