The Parasite of Mortex is shown here from WarCom. The latest from Games Workshop on the upcoming Tyranid codex.

The Parasite gets its name from its disturbing propensity to implant eggs into its unfortunate victims (although a xenological report in Codex: Tyranids is quick to observe this makes the Rippers the true parasites). It’s been observed in a growing number of war zones across the galaxy, but it was on the planet of Mortrex that this bat-winged nightmare was first sighted.
