What are some free easy-to-use softwares for making 3d models of creatures for a game?

Hi everyone. I am currently learning Blender and Zbrush to make my own games but I am wondering if there are any other easy, user-friendly free softwares with which a really good creation of characters like humanoid monsters in 3D (model + animations) can be achieved?
Thanks.
