Adult Zephonim are a type of enemy in Legacy of Kain: Soul Reaver. They are vampires and the descendants of the lieutenant Zephon. They are the older, more evolved members of Zephon's clan, in contrast to fledgling Zephonim.
As any other adults, they are not harmed by the dangerous sunlight. They have white skin and their body structure resembles a spider with their thin, prolonged limbs. They appear to have grown small wings on their shoulders, possibly to help them glide when jumping from great heights. They have a single Zephonim clan symbol on the left side of their chests. They are the only vampires which had grown back a third toe in order to adapt to the wall climbing in later stages of their devolution.
