GRUESOME Warhammer 40k Tyranids for my Custom Hive Fleet... 

Terrifyingly so

Came here to say the same thing! So true

No doubt.

Meaby add lore, prehaps they use visual patterns to confuse and overwhelm and consume plant biomass to create high sugar/calorie food for bioforms to improve thier metabolism

It helped me to recognize how natural adaptations in reality use what material is already there to create new forms. Because a Tyranid bioform can have so many variations, there must be some kind of base "template" from which new adaptations evolve. It makes sense that, in the way that bat wings have integrated finger and joint structures, the adapted weapons--usually a different bioform, symbiotically joined--would be integrated into the already-existing hand and claw structures that the bioform template already possesses. More than anything, biology strives to be calorie-efficient when it can. Why waste calories iteratively evolving a bespoke genetic expression for each distinct adaptation that might arise when you can just adapt one gene to express differently in the presence of certain other symbiotic relationships?

@Stephanie Aensland 3 I like your funny words magic man.

It helps that he’s a really talented drawer too, even if the shapes are basic, he perfectly captures the look.
