A founding member of the Atom Cats, Zeke explains the club has the most weapon and armor modifications around. According to his terminal entries, Zeke grew up in Diamond City until he left the settlement in dissatisfaction, referring to it as "a tilted square." He eventually found the Atom Cats garage after slaying a large pack of feral ghouls residing there. Afterwards, Zeke began recruiting the current members of the Atom Cats, most of whom came from troubled backgrounds in which he helped in reforming them by "[showing] them the way of cool."
Zeke has considerably higher health and level than the other Atom Cats, or most other NPCs in the game.
Zeke uses many cultural references that are appropriate and inappropriate for the time, including "Rustle his/her jimmies."
A safe with the name "Zeke's safe" can be found in the add-on Far Harbor on-board a grounded boat north of Rayburn Point. This indicates he might have been there at one time. The contents include: a Stealth Boy, burnt Grognak comic, burnt Manta-Man comic, burnt Unstoppables comic, Greaser jacket and jeans, sunglasses, and a teddy bear.
Zeke claims that he fixed up an old Vertibird but crashed it in the ocean.
