This is the Doot Revenant demon from id Software’s Doom Eternal built from Lego, complete with shoulder mounted trumpets and handheld detachable trumpet. The build consists of 324 parts and stands at 31 centimeters tall.

As a majority of the pieces on the Revenant model are in unofficial Lego colours, a UAC Revenant  model is included in the instructions that is designed with official Lego parts in official colours. This model is not very difficult to assemble and would be an excellent model for a diehard Doom Fan.

The Doot Revenant, UAC Revenant, Cacodemon and Baron of Hell are all built by me, the DoomSlayer is built by u/TheNinjaWhippet with their permission.
