The Broodlings of Chthon are a fictional race in the Marvel universe which first appeared in 2016 in issue #11 of the 2nd volume of the Carnage comic book series. They are a pastiche of the Deep Ones in canon.
The Broodlings of Chthon were created from mud by Chthon and live in the shadowy corners of the world, as they pray and wait for the return of their master. It's a race of reptilian humanoids, frog-like creatures. An ancient race that consists mostly of females.
They serve and worship Chthon, as well as the other Old Ones. To propagate the species, they capture human males and rape them, after which they are sacrificed to the Chthon. It's a race which is technologically primitive (e.g. spears and blades), that has access to Chthonic magic.
