Harridan

Harridans are one type of the fuck huge Tyranid Bio-Titans. Harridans however, are fuck huge Bio-Titans with wings. Because they're mostly airborne their legs have been reduced to stumps, and for some reason the moment they land is like a death sentence since they cannot take-off again...despite having EXBOXHUGE Wings! The Hivemind is still trying to fix this absurd problem (Master of genetics and evolution my ass, pffft).
They're basically a fucking insect dragon IN SPHESS!
