The new Tyranid Codex spawned a new model for the Great Devourer: the Parasite of Mortrex, a unique bio form that first appeared in 5th Edition and now gets its own model for the first time. We take a look at what’s in the box.

The Parasite of Mortrex comes in a small box with a single small sprue, a 40 mm base, and an assembly guide. The release follows the template of many small scale codex updates, with a single new character model and a Combat Patrol box as the only model releases.

Parasite of Mortrex unboxing

Let’s see what’s inside. Here is my unboxing short video:

As mentioned before, you get a single sprue without any additional build options, so no Red Terror build as some people have speculated online. The Parasite of Mortrex is monopose and has no posing options.

The Parasite of Mortrex was first introduced in the 5th Edition Tyranid codex but never got a model until now. The new sculpt shows some interesting and new design elements, especially the alien-like mouth and tentacle-like arms. Even though the basic concept has been carried over, there are subtle but noticeable differences to the classic Codex artwork.


With an RRP of £24 / 31.50€ / $38 the Parasite of Mortrex is quite reasonably priced for what you get, especially after the latest general price increase in March 2022.

You can (pre)order the Parasite of Mortrex along with the other new Tyranids releases from our partner stores Wayland Games, Element Games, and Taschengelddieb at a discount. Using our links helps to support Tale of Painters at no extra cost to you, thank you very much 🙂




  • Dynamic pose

  • Doesn't come with rippers

Final Verdict

Tyranid fans can look forward to a new specialised bioform with an intriguing design and dynamic pose. This must console the fact that many models in the range are desperately craving a redesign in plastic.
