There's a free adventure out there that has, as it's final, climactic battle, the PCs interupting a fight between a pack of werewolves and a werewolf lord. The monsters were unmodifed from their entries in the MM (3.5e).
The PCs were supposed to see this scene:
You can see why I (as a player => meta-gaming, I admit!

) was a bit thrown off. ...How were the werewolves able to damage the werewolf lord? Their attacks can only do 1d6+3, and they don't have power attack. The encounter is supposed to start for the PCs with the hybrid werewolf lord at
half hit points.
