One of the younger Atlanta survivors, Glenn represents the rare case of someone who arguably fares better in a post-zombie world than he did before the outbreak. Where before the cataclysm Glenn had an undesirable life as a pizza boy, afterward he’s able to utilize his adventurous spirit, daring and ability to evade zombies in the search for vital supplies to greatly benefit the group.

He eventually meets and falls in love with Maggie Greene, at first in opposition of her father’s wishes.

Glenn is always willing to assume dangerous assignments if he thinks they will bring benefit to his fellow survivors. He often puts the group ahead of his own interests, and even those of Maggie, often to her dismay.
