Blaze

Blaze is a type of mob that can be seen floating around The Nether. They catch fire for a short while before making their attack in the form of a three round burst of fireballs. After the attack they have a short cool down and then they will catch fire and attack again. Their bodies are made up of a head atop a central column of smoke, and three rotating sections, each rotating section contains four floating yellow rods. They drop Blaze Rods, and can spawn naturally or from a spawner in Nether Ruins. The triple fireballs they shoot can set players on fire. Unlike fireballs fired by Ghast, they are not explosive.

Trivia

 * Lighting has no effect on their mob spawner, as Nether mobs typically do not evaluate light when spawning. This is obviously because both there is lava almost anywhere in the Nether, and because most mobs in the Nether (including the Magma Cubes, Ghasts and the Blaze himself) are fire- or magma-based mobs, and are not, like the overworld mobs, dark and mysterious.
 * This mob takes damage over time from standing in water similar to the Enderman.
 * Blazes cannot shoot if trapped in a Cobweb.
 * Blazes do not have a body unlike other mobs. They are simply floating heads over a cloud of smoke surrounded by spinning rods.
 * Unlike Ghasts, projectiles fired by a Blaze cannot be deflected.
