Cinema has loads of default models (see Asset browser), and includes a range of humans for various animation purposes, but expecting to find one of superman is very specific, especially as it is copyrighted work, which would make its provision in the software almost impossible. And of course Cinema does contain ALL the tools you need to make your own superman model, but obviously you need some skill and experience to be able to do this - it is usually several years before people learn everything they need to know to be able to model, texture, UV, light, rig, animate and render a full character !!
I think you need to watch a few very beginner tutorials. PSR merely refers to Position, Scale and Rotation, any of which are freely animatable. But there used to be a function called 'Reset PSR' (now called Reset Transform in the Co-ords manager) which did (and still does) do what you describe.
