The Arch-Illager known by his birth name as Archie, is the first main antagonist of Minecraft Dungeons. He is the founder and leader of the illagers empire in the game, and is a proxy for the Orb of Dominance to carry out its goals.

Appearance:

In the opening cinematic, Archie has ragged and teared clothes and is holding a torch. When he is crowned the Arch-Illager, he has blue robes that are similar to the evocation robe, a large necklace with a ruby on it and a crown with a diamond and a ruby on it. He also carries a staff to hold the Orb of Dominance. The Arch-Illager is also the only illager to have a horizontal head and a smaller height. In the ending cinematic, the Arch-Illager is seen with what appear to be bruises or blood on his face. In Minecraft Dungeons Arcade, the top of the Arch-Illager's crown lacks a texture, only appearing black.
