Neutral creatures in Heroes of Might and Magic V.

Yeah, flying...
And it will attack enemies while in flight...
It's not worth creating elementals beyond what's necessary (5-6 types, IMO, is more than enough).

I completely agree. There can only be five elements - fire, water, earth, air, and magic. Neutrals can now only be something else. For example, birds could be used as neutrals. Different birds: Rocs, ravens, eagles;)
