So I want to create Arthas' Mount Invincible.

For People who haven't played WoW invincible is a skeletal warhorse with attached wings. If possible i would like it to be intellegent but im not sure if that is possible.

Here is what i have so far for the pre animated but i am not sure if it will carry over once it is killed and animated.
