This is a hero for the Warhammer Fantacy army I am going to try and present at Games Day: Anihiem.

The army is called "The Lycan Packs", they are tribes of werewolves and their Thralls. They are unique because they have no mounted calvary. Instead, they have certain units that transform into fearsome werewolves that count as fast attack.
That said, most heroes come with an on foot and mounted model, well Lycan Pack heroes come in a human and werewolf form.

They also have the ability to possibly turn enemy troops against them, once bitten, the werewolf Spirit Master (mage/ shaman) can use a magic dice roll to see if enemies killed in battle will rise and turn into Thralls, basically a meat shield. This is a good tactic because they don't have much in the way of artillery or ranged combat.

They are a very fast paced and "in your face" style of army. The Curse, the ability listed above, is helpful becuase is you bite an enemy archer squad, they have the chance to be yours.
