Converting Broodlords to fit my Aliens-themed Tyranid list involved pinning, and secreted resin.
Naturally, a secondary mouth-tongue was almost required modeling. A bit of putty and a sculpting tool gave this mini some character:
This mini was posed in a more "Genestealer-Pounce" style:
The other Broodlords took a bit of creative pinning took make them different from the pack:
All told, I made six separate minis in different poses. I removed the original Broodlord heads, and replaced them with the standard Tyranid Warrior frill. I think this makes the models stand-out from the swarm, and give them a sense of "evolved superiority" to the rank and file:
Enjoy!
