One notable feature of the franchise is the ability to "eat" the enemy Aragami during combat with the God Arc's "Predator Form".

"Control Units" are mods that can be equipped to the God Arc, giving status buffs upon entering "Burst Mode".

A cell phone game spin-off titled, God Eater Mobile was developed by Mobage and released on December 16, 2010 in Japan for the i-Mode, EZWeb, and Yahoo!

Similar to the original PSP game, it features character customization, item purchasing and hunting Aragami.

The Aragami are race of vicious creatures made from clusters of "Oracle Cells", single-celled organisms that can consume anything and take on its attributes, that devours most of the Earth's resources and much of humanity to the point of near-extinction.

Coming in different forms, they are invincible against any conventional weaponry, even capable of absorbing large quantities of nuclear energy into their own, until a Finnish pharmaceutical company known as Fenrir (フェンリル, Fenrir) created a series of biomechanical hybrid weapons called Jinki (神機, Jinki, known as "God Arc" in the English release) that can kill the Aragami, as well as selecting those who can wield such weapons.

First reported sometime in the year 2050, the Aragami is a race of mysterious beasts that had consumed a majority of the Earth's resources and pushed mankind to the brink of extinction.

Chosen through a series of aptitude test, the selected subjects are then painfully equipped with a bracelet containing the Bias Factor, a substance that determines what the Aragami should and should not "eat", as well as protecting them from getting devoured by their assigned God Arc.
