It was believed that Nefarian had been experimenting with the blood of all of the various dragonflights to produce unstoppable warriors. The drakonid in Blackrock Mountain appear to be the result of some of the black dragon Nefarian's experiments with the blood of different dragonkin. The other places they are found in and other dragonflights they are affiliated with may disprove that theory, but the initial assumption was that alongside the blood-based experiments that created the chromatic dragonflight, drakonid (then only found in Blackwing Lair) were created from the blood of dragonkin and humanoids, while was created from the blood of dragonkin and core hounds (likely ). Their origins are still mostly unknown, but they seem to come from empowered mortal humanoids.
They are meant to be the footmen and standard soldiers of the Legions of Blackrock, and though they have considerable magic resistances, a flaw does exist; each drakonid has a fatal weakness to one magic type, making it suffer enormous damage from that particular school. This weakness can be used to the advantage of any mortal army daring to step into the halls of Blackwing Lair in order to challenge the sinister .
Bronze colored drakonid can be found patrolling the Caverns of Time but are not hostile. Nether drakonid can also be found in Shadowmoon Valley, in the service of , while the infinite dragonflight also employs drakonid of their own flight. uses drakonids of all five primary dragonflights as the ground-based guardians of Wyrmrest Temple.
They have been said to be half-man, half-dragon, but this is likely a description and perhaps not to be taken literally. The Dragonmaw of Outland can also turn into drakonid. It is unknown how exactly they accomplish this, but it could be similar to how the Twilight's Hammer cultists achieve such a transformation. In Cataclysm, the Twilight's Hammer members in the Blackrock Caverns have been turned into drakonid as a type of 'gift'. Given the various origins given, it is more likely that there are simply multiple ways of creating drakonid rather than this being the sole method of creation. Coincidentally, both the Twilight's Hammer and the Dragonmaw in Outland capture and enslave the Netherwing Dragonflight's members.
