Metatron has been known by a number of different names, including (but not limited to) the following. The reasoning behind some of these names is explained in Metatron's article. Some items listed here are qualified as "possibly Michael" because these two angels have similar titles and roles, which makes distinguishing them difficult.

Inzebul - Originally ’izebūl, Where is Zebul' or 'Zebul exists', where Zebul is another name for Ball. Possibly repointed to ’îzebūl (Zebul is not), Repointed to ’îzebel (heap of dung) Another name for Jezebel. Unsure how this relates to Metatron.
