Giant

Giants are unused oversized versions of zombies do not spawn naturally.

Drops
Giants drop 5 experience when killed and have a chance of dropping some of its equipment, if it has any.

Spawning
No biome includes giants on their spawn list, so they will never spawn naturally. (The earliest available Infdev build (June 18, 2010) does not include Giants in the global spawn list.)

Additionally, giants simultaneously require a light level greater than 11 and less than 8. This effectively makes it impossible to make them appear through mob spawners.

Commands
Giants can be spawned such as.

Behavior
Giants are close to 12 blocks tall, and use a six-times-enlarged zombie model.

Giants currently have no AI. The consequence of this is that they always face south when summoned and stay that way, never wandering, turning their head, chasing the player, or responding to damage except for taking knockback. Their viewing direction can only be changed with commands or if you shove them into a minecart that is facing another direction.

Giants are in the Xbox 360 and Xbox One (legacy version) editions, although they require external modifications for their spawn egg to be placed in the player's inventory.

Data values
Giants have entity data associated with them that contain various properties of the mob.

Issues
Giants are an unsupported mob and as such issues relating to them may not be fixed.

Trivia

 * Since giants need to have a light level both less than 8 and greater than 11 to spawn, they don't spawn from monster spawners. However, this spawn condition can be bypassed with a custom spawner, if it attempts to spawn an entity with valid spawn conditions riding a giant.
 * If the player names a giant using a name tag, its name will appear inside its head.
 * Giants share the exact same model as the zombie. This means that changes made to the zombie model change the giant's as well.
 * Notch removed the giants spawning capabilities because "they are too overpowered". He did not remove them entirely because "they are just too cool to remove".
 * If a giant is riding a minecart, it hovers way above it.
 * If a mob is riding a giant, unless it's a very large slime or magma cube, a ghast or the ender dragon, it is completely hidden from view by the giant's head.
 * Giants are damaged by potions of harming despite the fact that they use the zombie model, which is an undead mob.
 * Giants have the same hurt sound as the player does.
 * The giant's head and torso are not included in its hitbox, meaning hitting it in those areas will not hurt the giant.
 * Iron golems are hostile towards giants.
 * Giants, being capable of dealing to, and having  health, means they are the strongest and hardest-to-kill mob in the game, capable of killing the player in one hit even in Easy difficulty.
