This monster's name derives from the Zeta Reticuli, a star system in the southern constellation of Reticuli.
Zeta Reticuli gained notoriety in ufology after alleged alien abductees Barney and Betty Hill as the home of their abductors. This card's name, as well as its resemblance to the "Alien" archetype, are most likely in reference to this.
The "EBE" in "EBE Token" (the original name for an "Eva Token") is an abbreviation for "Extraterrestrial Biological Entity".
This monster strongly resembles a member of the "Alien" archetype, even though it is Fairy-Type.
This is further supported by the fact that it was used in a cosmic-themed Deck by Depre Scott.
