Caretaker

The Caretaker was an AI in Fortnite: Battle Royale. It was introduced in Update v18.21.

Behaviour
Formerly, at the start of the match three Caretakers spawn at random open areas and begin to traverse the map, while being mostly invisible. Their locations are indicated with symbols on the map.

When alerted, If the place is suitable for battle the Caretaker would create a Sideways bubble and the player will be pulled in. He cannot receive damage outside of the bubble. His hole in the chest is the weak spot, hitting it will count as a headshot.

Attacks
Caretaker can attack players in three ways:
 * Beam Attack: After a short charge-up, a pink laser beam comes out of his chest, dealing 8 damage per tick.
 * Smash Attack: Caretaker slams the ground, the shockwave damage depends on how far the player is (20 to 60 damage).
 * Snap Attack: A pink electric web will come out of his hand and will stun the player for a second, dealing 20 damage.

Loot
The Caretaker drops 5 weapons, Healing Items and Cube Monster Parts when eliminated.

The End
During The End event, multiple Caretakers were unleashed by The Cube Queen as the island was being covered with Cubes. They were pushed off with the assistance of Rebooted Cube, The Visitor and The Scientist. Later on, as the player approaches the epicenter of the island, a massive Caretaker smashes a seemingly indestructible skylight causing the player to emerge in the ocean, far from the Island.
