Put a mob's head on. Press R. Become the mob.
Explode like a creeper and walk away. Teleport like an enderman. Fire a Warden sonic boom. Fly with the dragon head. And walk straight past zombies, because with a zombie head they think you're one of them.
HOW IT WORKS
1. Kill mobs. Sometimes they drop their head (Looting helps).
2. Wear the head (helmet slot or right-click it).
3. Press R to use its power. Every head also gives a passive while worn.
4. Most heads are a disguise: that kind of mob ignores you until you attack it.
A small icon next to your hotbar shows your power and its cooldown.
ALL 16 HEADS
Creeper - Explode, you survive / Immune to explosions

Skeleton - 7-arrow volley / Speed
Wither Skeleton - Shoot wither skulls / Immune to wither
Piglin - Barter a gold ingot anywhere / Piglins stay calm
Dragon - Dragon breath / Fly
Enderman - Teleport where you look / Endermen don't get angry
Blaze - Triple fireball / Fire resistance
Spider - Web shot / Climb walls, see in the dark
Ghast - Explosive fireball / Slow falling
Slime - Super bounce / Jump boost, no fall damage
Iron Golem - Ground slam / Resistance

Witch - Throw nasty potions / Immune to poison
Guardian - Laser / Water breathing
The 6 vanilla heads (creeper, zombie, skeleton, wither skeleton, piglin, dragon) get powers too, and now drop from their mobs. The 10 new heads use the mobs' real in-game textures, no custom art shipped.
Balance: you can never hold more than 3 heads at once (worn plus inventory). Trying to pick up a 4th leaves it on the ground with a message.
