Zeke (ジーク, Jīku) is a puppy found by Alice Maresato and taken in by Takashi Komuro's group. Before the events of the main story Zeke was shown to have belonged to a young lady the status of which is currently unknown but presumably dead. Despite being small, Zeke is show to be brave and energetic willing to protect Alice when being attacked by "them". Throughout the series, Zeke has shown to have acute senses, and is often the first to detect the presence of "them" before the other survivors. Zeke's name was given to him from Kohta Hirano who derived it from the American Army's codename for the Mitsubishi Zero fighters from WWII, "Zeke".
