Television SeriesEditGlenn met Rick Grimes during one of his frequent forays into Atlanta to scavenge much-needed supplies to sustain the camp, where he notices Rick being chased and getting trapped inside a tank by a horde of Zombies.
Glenn is keenly aware of the extreme danger of his scavenging missions, but because of his youth, he is willing to take the risk. He used to deliver pizzas for a living, and his knowledge of every shortcut in town proves extremely useful to the group's scavenging needs.
Young and resourceful, Glenn thinks on his feet and shows great compassion and humanity. Despite all the horrors he has seen, he maintains a youthful enthusiasm for life and its unexpected pleasures. He is an integral part of the camp, showing surprising depth and emotion when the group experiences a devastating tragedy.
Glenn lived in the town of Macon where he delivered pizzas for a living. He seems to know the city fairly well and can navigate his way through back alleys and the streets as well. When the outbreak began and the city converted into a refugee center, Glenn, being resourceful, was able to survive despite the city slowly becoming overrun with walkers.
Glenn is one of the few remaining survivors of the original Atlanta band, and a civilian who has survived the mysterious undead apocalypse that has swept the planet.
Before the epidemic, Glenn was a pizza delivery boy in massive debt. He had several payments for his car and his apartment burdening him, as well as a severed relationship with his parents. Several questionable skills such as being able to hot-wire a car were acquired in his college years due to his monetary debts; Glenn says to Rick he was forced to steal cars with friends to make a living, although he also admits he enjoyed the experience.
Glenn revealed his financial trouble eventually became so extreme, he almost lost everything. He begrudgingly told his fellow survivors that this problem would have forced him to crawl back to his estranged parents for help. His hopes for anything to get him out of it came true, in a way, when the dead began to rise.
Glenn is a younger member of the survivor group, and a major character within the series. Under unexplained circumstances, Glenn made it out of Atlanta and joined the survivor group living on the outer limits of the city. He was the fourth survivor present to establish the camp. His importance to the group arose when he willingly served as their primary supply source by frequently venturing into the city. He scavenged much-needed supplies despite the extreme danger to him. He displayed a vital skill in his quick adaption of evading and fighting off zombies while finding the needed items. On one of his outings, he managed to rescue and befriend an overwhelmed and alone Rick. Glenn informed Rick of the latest details concerning the United States government's collapse, before escorting him back to the camp.
Glenn's selfless risks to obtain supplies and his rescue of Rick gained the latter's respect and admiration. This eventually culminated in Rick requesting Glenn's assistance to venture deeper into Atlanta to recover much needed weapon supplies for the group. He expressed concern once Jim told him the location of the gunstore, but he, along with Rick, covered themselves in zombie gore to avoid being detected and eaten by the masses. The pair successfully made it out of the city with the firearms.
