Character Templates

Hi folks! I want to improve my portfolio with a new scene that I am planning . However, the template I had was too simple for what I need: https://www.toonboom.com/resources/templates/simple-game-bone-deformation-puppet-template

Is there any bank that I could download a rigged character a little bit more complex?
Or if some of you have such character, can I use it and of course credit in my demo reel?

Cheers
