Suppose I should share ideas behind my design...
The 'typical' appearance of Shrikes is that of a generic warrior where wings replace the upper limbs while also acting as scything talons.
I never really liked that... So fluffed my way out of it and into a different idea.
My Hive Fleet (Munc'Kin) was initially little more than a tiny tendril on a much larger fleet.
That tendril was ultimately defeated in orbit above a T'au world, however in the process the T'au sent various hive ships to oblivion via atmospheric re-entry.
1 Hive Ship survived and a tiny remnant impacted a remote section of the worlds ocean. That Hive Ship held a Norn Queen.
That Norn Queen from the abyssal depths had practically limitless biomass with which to heal, re-build and evolve.
The native fauna of the T'au world of Munc'Kin was largely prehistoric and the evolution of various Tyranid strains represented the biomass from which they were harvested.
Oceanic 'Plesiosaurs' initially became the Trygon strain of the Hive Fleet before later evolving to the land based snake like organisms, later on in the consumption of the world the 'Pterosaurs' would become the basis of the Shrike's template, and eventually the Whole Warrior strain.
The Pteroshrike evolution had forelimb wings that were exclusively used for flight, and as such the beast required less and less use of hoofed feet, instead the were re-evolved by the Norn Queen into scyting Talons, allowing the Pteroshrikes to engage in flying hit and run attacks as they no longer needed their wings to attack effectively.
The evolution was so successful that it has been kept for a significant period of time now despite numerous worlds being lost to Hive Fleet Munc'Kin the Shrike form has only changed slightly, the overall bodyform still outperforming variants created from other, newer biomass.
Munc'Kin's Shrikes are rarely seen with ranged bio weapons, instead appearing with swarms of Gargoyles and winged Tyrants that prefer to engage their prey in close quarters.
I present for the competition my initial brood of Shrikes with twin Bone Swords for hunting down large, tough prey.
Your death comes from above!
