Griggs was a one-episode character featured in the second season of Eden Rising. He was the army lieutenant of a troupe stationed at Tulsa International Airport.
Nothing is known about Griggs's past.
Griggs was the highly-respected lieutenant and leader of the army troupe stationed by Eden at the Tulsa International Airport. Griggs was somehow suspicious of a traitor in his group's midst and, after learning this and the fact that one of Tom Snyder's group, the leader's own daughter Darla, was bitten by a zombie, took matters into his own hands. Using a rocket launcher from the armory at the airport, Griggs blew up the plane that was going to take the survivors to Eden. In a rage over the situation, Tom ambushed Griggs, beat him down and then unloaded the entire clip of his pistol into Griggs' face, killing him.
The nature of Griggs's death left his army friends and Tom's group of survivors at a split and eventually led to Michael, an unstable and angry soldier, taking control and commanding the rest of the men to turn on Tom's group and kill them. The soldiers were eventually all taken out and Tom's group claimed the airport as their own sanctuary.
