He spends his days with his friends, surfing, playing the ukulele and throwing poi parties down at the beach with the local lady lizards. After his father dies, Gex begins watching mass amounts of TV to get over the tragedy. He eventually inherits over 20 billion dollars from his deceased uncle and buys the world's largest TV.
He has his own private island hideaway called the GEXCave located in the South Pacific. His catchphase is "It's tail time!".
