Younger Brother of the former Zombie Attack character Elias Cash, who died in the previous series. 

Member of N.EP.O's special task force. Unbeknownst to everyone else, Gordon also holds a large amount of scientific and genetic knowledge. That is all that is currently known.

An excellent and efficient soldier (though sometimes TOO self-absorbed), hoping to continue his Brother's fight, he's joined James' team in their efforts to stop the world's demise.

He's brash and cocky, thriving in his youth, but also very proud and determined.
