Aside from his role as a brilliant scientist, Professor acts as parent in The Powerpuff Girls' lives (doing things a father would normally perform, like preparing their school lunches or cheering up his "daughters" when they've been hurt). Although the girls address him as "Professor", when discussing the Prof with others, they refer to him as "our dad". The Professor can be odd, silly, clumsy, easily manipulated and over-protective at times, but still retains his caring father figure image.
