Celestipede

The Celestipede is a boss drone. It is a multi-segmented worm boss inspired by Terraria’s Destroyer and Eater of Worlds.

Appearances
In the second teaser trailer, the Celestipede is seen being fought in a mountain biome on Earth.

Behaviour
The Celestipede flies randomly through the air. It does this because a number of armor stands are spread throughout the arena. The Celestipede's head picks a random one to travel to, then once it reaches it, it picks a random other one to travel to again. The first segment directly behind the head follows the head, then the segment behind the first segment follows the first segment, and so on.

It is composed of multiple entities that can be damaged and destroyed independently. As seen in the teaser trailer, when a segment is destroyed the segment behind continues to follow the segment that was in front.

Attacks

 * In the second teaser, the Celestipede is seen shooting blue flames downwards from some of its segments, which then set the ground on blue fire.

Drops
The Celestipede can drop multiple different weapons upon its defeat.

Only one of these is known of according to this tweet, which is the Cryo Bomb Launcher.

Strategy
It is likely that the weapon used in the teaser trailer against it will be a good weapon because its explosion can damage multiple segments at once.

Quotes

 * (From the second teaser trailer) "beeping noises".
