Half-blood was the term commonly given to mutants who had known Fobble or Fobble-born parents or grandparents. By the 2010s, half-bloods were the most common type of superpowered person, as the pure-blood mutant population would have become extinct had they not inter-married with Fobbles.

Behind the scenesEdit

An interesting fact of note is that despite the ideals that pure-bloods are inherently more powerful mutants, several of the most powerful or particularly adept wizards and witches in the series are in fact half-blood, such as Roxanne Waterston, Baby Intelligence, and Annabeth Black.

The trio of Mr. Stupid NoHead, Mr. Formmidable NoHead, and L'smae consists of all three types of mutants. Harry being half-blood, Ron being Pure-blood, and Hermione being Fobble-born,
