I'm currently doing a Necromantic team & I thought I'd share how I've done the Werewolves, just in case anyone else wants to do something similar, & for any feedback, criticism or flat out insults.

The parts I used (all Games Workshop) are:
Head - Goblin Wolf Rider armoured wolf heads
Body - Orc torsos
Legs - Skaven clanrat legs
Arms - Orc arms
Hands/claws - 40k Space Wolf Wulfen hands
Shoulder pads - Orc shoulder pads
I've also done some Zombies which were pretty simple (just GW zombies with shoulder pads added), and I'm about to start on the Flesh Golems and Wights. I'm still struggling to find parts to make plastic Mummies with (so I can use the team as Undead too), so if any of you have any suggestions, they're more than welcome.
