Hybrids are beings that are similar to demimyths in many ways, but the one difference is that they don't have any human blood within them (for the most part). Also, they cannot swap forms, like their demimyth counterparts (with the exception of werebeast hybrids). Most hybrids only identify as a hybrid of their parents (e.g. merman/shinigami, dragon/maenad, werewolf/akhlut, etc), however, there are some hybrids that are called something else entirely. The list of these hybrids can be found here.
Hybrid appearances differ depending on their parents.
Hybrid behavior depend on their parents.
