Heavy Worker Drone

The Heavy Worker Drone is a drone that appears to be a stronger version of a Worker Drone.

In the first teaser trailer, the Heavy Worker Drone is seen being fought somewhere on the Celestial.

Behaviour
The Heavy Worker Drone appears to function similar to melee mobs. It inflicts the Wither effect on contact.

Trivia

 * The Heavy Worker Drone was first seen in the seventh tweet posted during the 12 Days of Christmas in 2018, where a screenshot of it with a 'dynamic boss health bar' was posted. It was seen again at the end of the first teaser trailer.
 * The location that the Heavy Worker Drone is seen in both of these reveals is different, perhaps implying that the Heavy Worker Drone is a rare mob similar to for example the Creeper Knight from Assassin of Steve or a mini-boss.
