Mortarion, Death Guard Primarch/ Chaos Lord Resin Alternative!
Old School here to talk about what I think is the best Mortarian model created to date - Archfather Mortimer, the Harvester of Sorrows from Hi-Tech Miniatures. I have searched long and hard for a model that could fill the role of Mortarian and the fact of the matter was that without seriously rolling up my sleeves, that model just didn't exist.
This model is as close to a true Daemon Primarch Mortarian as I have seen at an appropriate scale (the model stands 45mm tall) that is available to the masses. The model has a great "Angel of Death" theme
