When the Atlanteans came to the seas, they fought for millennia against the Great Old Ones and their spawns, driving them into the depths, killings or imprisoning them.
No being has been confirmed explicitly as a Lesser Old One, but many have been stated to be either Great or Lesser Old Ones, including Asteroth, the Black Gods of R'Lyeh, Erlik Khan, Ghaszaszh Nyrih, Gol-Goroth, Kathulos, N'Gabthoth, Nigguraab, Shub-Niggurath (the Black Goat gods), the Toad God, Thog the Ancient, and Yog-Sokkot.
Though not explicitly stated as such, per the Lesser Old Ones' definition, "powerful servants and spawn of Great Old Ones", Lesser Old Ones could include Quoggoth (a rebellious creation of Shuma-Gorath), the spawn of Chthon (usually classified as Elderspawn due to Chthon being traditionally an Elder God of Earth, though being described as a Great Old One on occasion) such as the Broodlings of Chthon, and (depending of Dagon being a Great Old One or not) Dagoth, Khosatral Khel, and the fishmen.
- That classification was created by Lin Carter in the short story "Behind the Mask" (Crypt of Cthulhu #47, Roodmas 1987).
- In Marvel Comics, the Old Ones were usually called "Old Ones" with some sometimes named "Great Old Ones" (among other names). In the demons' profile in Official Handbook of the Marvel Universe A-Z #3 (July, 2008), updating the profile originally published in Marvel Zombies: The Book of Angels, Demons & Various Monstrosities (September, 2007), the Old Ones were named Great Old Ones instead, while three distinct but often confused groups, the Lesser Old Ones, the Outer Gods, and the Other Gods, were introduced.
