You cannot do complex character animation in Unity.

You can apply and retarget these animations very effectively in Unity using Mecanim, but these should be created outside of Unity: Blender, Maya, Max, MoCap…

Look on the asset store for Mecanim Sample Scenes and 150 free animations.

Unity doesn’t produce that good animation so I advice you to use a program who is primary function is animation like blender
