Empties

The are creatures created by Deathpierce through the use of a Chaos Staff, to serve as part of his army on his fight against the Kingdom of Liones.

Appearance
Empties are large void armors animated by Chaos magic. Their bodies are tall and slender with a pink and gray pattern, they have long necks with round heads. They have small purple eyes shaded with a black cross in both of them with mouths similar to the eyes but grey in the middle.

Personality
The Empties don't seem to have a mind of their own and just do whatever they're ordered to do by their creator.

Grudge of Edinburgh
In order to fulfill his goal of eliminating non-human races and taking revenge on the current kings of Liones, Deathpierce uses the Chaos Staff that Arthur Pendragon gave him to create his army of Empties. They begin a campaign kidnapping lots of fairies, giants and even demons.

Tristan faces a group of Empties to save the fairies and giants they were kidnapping, although during the fight he limits himself to reflecting their attacks wanting to avoid killing them, something that a fairy there ends up doing, reproaching him that the Empties are nothing more than animated armors.

Upon arriving in Edinburgh, Tristan and the fairy, later revealed to be the transformed Lancelot, are ambushed by two waves of Empties and two of Deathpierce's followers. The two make it through fighting and with some distant help from Jericho, reaching the castle.

When Meliodas, Ban and Gowther appear, Deahpierce orders all the Empties to attack, but Meliodas returns every last shot with Full Counter. The three then make their way easily, eliminating every last one of the Empties.

Abilities/Equipment
Empties are living armors animated by the magic of a Chaos Staff. They are shown to have great strength and speed where as a group they managed to defeat and capture some members of the Fairy and Giant Clan. They can walk and run either in a bipedal or quadrupedal fashion. They have a certain degree of intelligence where in their confrontation with Tristan they realized that their magic attacks were being reflected by him and that it would be better to attack with physical attacks.

They are able to shoot multiple purple fireballs reminiscent of Hellblaze in rapid succession.

Weapons
Each Emptiy is equipped with a long spear.
