Zeke

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 whom is currently unknown but presumably dead. Despite being small, Zeke is shown 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".And shown in the anime "them" never really attacked Zeke but just walked past him.

Trivia

 * In the English dub for the anime, Zeke's name is changed to "Zero," after the fighter planes used by the Japanese during World War II. Kohta bases the name on 'Zeke' being "fast and small," much like the plane in question. Note that "Zeke" and "Zero" are both nicknames for the same aircraft, the Mitsubishi A6M"Navy Type-Zero" fighter, Allied reporting name "Zeke" and more commonly known as the "Zero"
