Larry Ellison is ... Iron Man
Like Tony Stark, Larry Ellison is a man of large appetites -- whether for acquiring smaller companies (86 and counting), wives (four and counting), or the America's Cup (only one so far, but give him time). What Larry wants, Larry eventually gets, even if it requires spending billions of dollars and/or laying waste to major metropolitan areas. Why settle for being the planet's fifth richest man when you could be No. 1? Only a heart-size cold fusion reactor could power an ego this large.
