Leo is a member of a group of 4 survivors of a Zombie Apocalypse. He is confident, and has foul mouth with a tendency to get angry very often. He was once soldier before the apocalypse so has a fondness for weapons, specifically Assault Rifles. He has a deep hatred of Lucas due to the many dangers he has put the group through, whilst he also gets along with Rex, he does get frustrated with Ted, whom Leo believes trusts Lucas too much. 

He is another one of the four playable characters and is planned to reappear in future maps also.
