CAVE JOHNSON (ECCENTRIC DEAD BILLIONAIRE)] 
Cave Johnson is a character for a new game in the Portal series from Valve Software. Portal is a dark comedy; 
the role will require comic timing, with occasional dramatic moments. Age: early 60s. He is founder and CEO of a successful 
applied science company, a self-made billionaire who's learned to trust his gut and doesn't sweat the details—is a big picture 
thinker. He might not know how science works, but he knows how people work. Used to getting what he wants. Extroverted, 
enthusiastic and opinionated. High energy: life is an adventure he's happy to be on. A born salesman, a leader, an evangelist. 
People trust him, even when his plans are clearly dangerous. Speaks with a slight Southern/Western accent (natural, not too broad). He a 
uses warm, homespun delivery to put people at their ease. He doesn't accept the responsibility that comes with his power. Either 
he doesn't see or chooses not to see the ramifications of his actions. Goes from sidekick to principle antagonist. Sarts to 
lose his grip on his humanity as the story progresses. As he isolates himself from the people around him, 
he loses touch with reality...VOICE OVER ONLY [sic]
