From publisher blurb:
Blackdyrge's Templates returns with a new template based on the fearsome god-serpent from Egyptian mythology: Apophis. The spawn of Apophis are the half-mortal progeny of the fell deity, and are possessed with the same rapacious and destructive nature as their divine progenitor. All spawn are gifted with a host of terrible abilities that includes: a charming gaze, virulent poison, and the horrific ability to swallow their prey whole and wriggling.
So if your dragons, serpents, and other scaly creatures just aren't fearsome enough, give them a kick with Blackdirge Publishing and the spawn of Apophis.
Blackdyrge's Templates - Spawn of Apophis contains 10 pages of new d20 material and includes the following:
