Of the Equip Spell "Guardian" monsters, this card has the longest gap between its anime debut and real-world release. It is also the only one whose corresponding Equip Spell Card was not released at the same time it was and thus one of two such "Guardian"s that does not need that Equip Spell face-up to be Summoned.
Indeed, this monster and "Guardian Dreadscythe" (the only other "Guardian" to not have this Summoning condition) are the only two such "Guardian" monsters to not have their correlating Equip Spell weapon visible in their artwork.
The alternative name of Eatos, Aetos, means "Eagle" in Greek, though "Aetos" is a masculine word, while this monster is female. (However, as word-gender and true-gender are independent for non-person entities in Greek, female eagles would also be referred to as such.)
This card resembles both an Angel and a Native American warrior.
