Which monster do you like the most in Heroes 5 at level 7?

I like almost all of them except the Bone Dragon. He's too weak compared to other level 7 creatures, and his abilities aren't impressive.

Even though he's weak, his growth is 3, you can raise killed enemies, and he curses pretty hard! The Necropolis' strength isn't in quality, but in quantity! Plus the Banshee's wail...:(
