Genasi

Genasi are one of the three "core" Planetouched races of Dungeons & Dragons, alongside their cousins the Aasimar and the Tiefling. Descendants of rare unions between mortals and the elemental races, they possess a natural array of elemental abilities and affinities based on that ancestry.   They should not be confused with with Mephlings, which are basically the same fucking thing, or Mephits, which are pure elemental beings.   Like all planetouched, at least in theory, genasi are extremely mutable; even two genasi from the same species of ancestor might look wildly different. For example, one water genasi might be covered in fish-scales and have webbed hands, a second might look like a humanoid frog, and a third might be a normal human with blue hair. However, genasi are the black sheep of the planetouched trio; unlike both aasimar and tieflings, they never got a table of randomized traits or optional powers - in a fit of irony, not only are elementals regarded by many as one of the blander "outsider" races, but even their planetouched seem to be regarded in the same light.   As with the other planetouched, whilst technically any mating of humanoid and elemental can result in a genasi in theory, in practice it's the human-descended who get all the limelight, in typical D&D halfbreed fashion. Save for in 3rd edition where earth genasi were explicitly noted to come from non-human stock. Dwarves and Gnomes to be precise, which only becomes more hilarious the more you think about it. ("When a dwarf loves his mine very, very much..." Bram Rockfucker, etc.) 3e even introduced two demihuman genasi strains in Dragon Magazine #350; the Azerblood and D'hin'ni, genasi of dwarf/azer and halfling/djinn ancestry.
