Giant

Giant is an enormous zombie that exists only in Java Edition. It looks exactly like a Zombie scaled up to 12 blocks tall, with 100 health, which makes it one of the largest mobs in the game.

No player meets a Giant by chance. It never spawns in any world, there is no spawn egg for it, and no structure or spawner holds one: only a command makes it. Type /summon giant with cheats on to see one.

Once summoned, the Giant does nothing. It has no behaviour of its own, so it stands where it appeared and never walks toward players. The game gives it an attack strength of 50, but it never uses it: a Giant does not attack. Defeating it drops no items, only experience. Map makers use the Giant as a giant statue or a backdrop, since it will not wander off.
